1.3 General Description
1.3.1 BNP blast cabinets enclose the blasting
environment to provide efficient blasting while
maintaining a clean surrounding work area. Production
rates are influenced by size of nozzle, compressor
output, working pressure, type and size of media, angle,
and distance of the nozzle from the blast surface. BNP
suction cabinets consist of three major components:
1. Cabinet Enclosure
2. Reclaimer
3. Dust Collector
1.3.2 Cabinet Enclosure: This manual covers two
BNP cabinet sizes. Each is available as a conventional,
stand-up model and ergonomic, sit-down model; totaling
four separate cabinet models.
BNP 65 Approximate work chamber dimensions:
36" wide x 35" deep x 37" high.
BNP 220 Approximate work chamber dimensions:
50" wide x 39" deep x 43" high.
NOTE: The extended front on ergonomic models
provides approximately 12-inches additional depth
from the arm-port and above, and is approximately
3-inches narrower than the widths shown above.
1.3.3 Refer to Figure 1 for arrangement of components
with a CDC-1 dust collector. The illustration shows a free-
standing 900 reclaimer; 300 and 600 reclaimers are
mounted on the back of the cabinet. Figure 2 shows the
arrangement with a RPC-2 (600 cfm or 900 cfm)
reverse-pulse dust collector with dust drawer. The
optional RPH-2 (600 cfm and 900 cfm) or RPH-3 (1200
cfm) is set up the same way as the RPC, but includes a
hopper for additional dust storage, and empties into a
drum. The overall height of the RPH is approximately 10-
feet, 6-inches, and 12-ft when the top access door is open.
An upgraded, RPC or RPH collector may be added at any
time.

1.4 Theory of Operation
1.4.1 Once the components are correctly setup and
turned ON, the cabinet is ready for operation by
actuation of the foot pedal. Fully depressing the foot
pedal causes air to flow through the blast gun. Air moving
through the gun draws media into the gun’s mixing
chamber. The media mixes with the air and is propelled
out the nozzle. After striking the object being blasted, the
blast media, fines, dust, and by-products generated by
blasting, fall through the mesh worktable into the cabinet
hopper. These particles are then drawn into the reclaimer
for separation. Lightweight dust and fines remain airborne
and are drawn out to the dust collector. Heavier reusable
media fall through the screen into the reclaimer hopper for
reuse. The dust collector traps dust and fines and
discharges clean air. When the foot pedal is released,
blasting stops.
1.5 Reverse Pulse Dust Collector Options
WARNING
Prolonged exposure to any dust could result in
serious lung disease and death. Short term
ingestion of toxic materials, such as lead dust or
dust from other heavy metals and corrosives,
could cause serious respiratory injury or death.
Identify all materials that are to be removed by
blasting. Use reverse-pulse dust collectors with
HEPA after-filters if lead coating or any other
toxic materials are being removed by the
blasting process.

1.5.1 CDC-1 Dust Collectors: Shown in Figure 1, the
collector is available in 300, 600, and 900 cfm models.
The single filter cartridge is cleaned by using a manually-
controlled pulse of compressed air. CDC-1 dust collectors
are standard with BNP cabinets unless an optional RPC-
2 or RPH dust collector is ordered at time of purchase.
Refer to manual number 28225.
1.5.2 RPC-2 Dust Collectors: Shown in Figure 2, this
collector is available in 600 cfm and 900 cfm models.
Dual filter cartridges are automatically cleaned by a
timed, periodic pulse of compressed air. Dust collects in
the drawer and must be frequently emptied. Refer to
manual number 22788.
Figure 2
1.5.3 RPH-2 Dust Collector: The RPH-2 is available
in 600 cfm and 900 cfm models. It is set up and
operates the same as the RPC-2, as shown in Figure 2,
but instead of a dust drawer, the collector sits atop a
hopper, which provides additional dust storage, and
empties into a drum. Refer to manual number 21449.
1.5.4 HEPA (high-efficiency particulate air) Filter:
HEPA after-filters provide additional filtration and must
be used with a reverse-pulse cartridge collectors when
removing lead coatings or any other toxic materials.
1.6 Nozzle Options
1.6.1 Unless otherwise specified at the time of
purchase, the cabinet is shipped with a No. 5 (5/16"
orifice) ceramic nozzle and No. 5 (5/32" orifice) air jet.
Optional, more durable tungsten carbide and boron
carbide nozzles are available and are shown under BNP
Gun and Feed Assembly in Sections 9.3. Use a boron
carbide nozzle when blasting with aggressive media, as
noted in Section 1.8.4.
1.7 Reclaimer Options
1.7.1 Replaceable rubber reclaimer liners: The liners
prolong service life of the reclaimer, and should be
installed when using silicon carbide, aluminum oxide, or
other aggressive media as noted in Section 1.8.4. Rubber
liners are available for 600 and 900 cfm reclaimers that
have a removable top and are designed to accept liners.
Rubber liners are shown on Page 25, Figure 30.
1.8 Blasting Media
WARNING
Obtain Safety Data Sheets (SDS) for the blast
abrasive. Abrasive blasting with sands
containing crystalline (free) silica can lead to
serious or fatal respiratory disease. As NIOSH
recommends, do not use abrasives containing
more than trace amounts (more than one
percent) free silica.
NOTE: Use only abrasives specifically manufactured for
blast cleaning which are compatible with the surface
being blasted. Abrasive produced for other applications
may be inconsistent in size and shape, contain particles
that could jam the abrasive metering valve, or cause
irregular wear.
1.8.1 ZERO cabinets utilize most common reusable
media specifically manufactured for dry blasting. Media
sizes listed under media headings and in Figure 3 are
for guidelines only. The guidelines are based on
standard nozzle size and average conditions, such as
blast pressure, media/air mixture, visibility inside the
cabinet, humidity, and reclaimer cleaning rate.
Several factors affecting the reclaimer cleaning rate
include: reclaimer size (cfm), contamination of parts
being blasted, media friability, damper setting (static
pressure), and dust collector filter loading (differential
pressure across the filter cartridge(s).
As a rule, larger nozzles deliver more media, requiring
higher performance from the reclaimer. When using
larger nozzles, the maximum mesh size of media will be

smaller than those normally recommended. Using media
finer than those recommended may decrease visibility
and increase carryover to the dust collector. Media
coarser than those recommended may be too dense for
the reclaimer to recover from the cabinet hopper.
1.8.2 Steel and Shot: Standard cabinet models
configured for steel media use are available with 900 cfm
reclaimers. They include appropriately sized conveying
hose and rubber curtains to protect the cabinet walls from
peening and rapid wear.
Switching to steel media requires a smaller diameter
conveying hose (usually reduced one size from standard)
and a 900 cfm or larger reclaimers. Rubber curtains should
be used to protect the cabinet walls from peening and
rapid wear. NOTE: Steel grit or shot is too heavy to use
with cabinets equipped this 300 and 600 cfm reclaimers.
1.8.3 Sand and Slag: Sand should NEVER be used
for abrasive blasting because of the respiratory hazards
associated with media containing free silica. Slags are not
recommended because they rapidly breakdown and are
not recyclable, making them unsuitable for cabinet
applications.
1.8.4 Silicon Carbide, Aluminum Oxide, and
Garnet: These are the most aggressive of the
commonly-used media. Aggressive media may be used,
but the service life of any components exposed to the
media will be reduced. To avoid unscheduled down
time, periodically inspect the reclaimer wear plate, flex
hoses, blast hose, and nozzle for wear.
When using aggressive media only occasionally, install an
optional aluminum oxide kit. The kit includes rubber
curtains for the cabinet interior and a boron carbide
nozzle. When using aggressive media on a regular basis,
install the aluminum oxide kit and a fully-rubber-lined
reclaimer. NOTE Rubber-lined reclaimers are available as
factory installed items and can be field installed on
reclaimers if they have removable tops and designed to
accept liners. Nozzles lined with boron carbide extend
nozzle wear life. See Optional Accessories in Section 9.1.
1.8.5 Glass Bead: Most beads are treated to ensure
free-flow operation even in environments of moderately
high humidity. Glass beads subjected to excessive
moisture may be reused only after thorough drying and
breaking up any clumps.
1.8.6 Lightweight and Fine-mesh Media: When
using lightweight (such as agricultural) media or fine
mesh (180-mesh and finer) media, the reclaimer inlet
baffle may need to be removed to retain media and
avoid carryover. On reclaimer models with bolt-on
removable tops, baffle removal and replacement is
easily accomplished. Reclaimers with welded-on tops
require grinding to remove the baffle and once it is
removed it cannot be replaced.
1.8.7 Plastic Media: Plastic and similar lightweight
and/or non-aggressive media are generally not
recommended for suction-style cabinets because the
lower blast velocity of suction blasting combined with the
softer and lighter weight media, do not provide the
media impact for productive blasting. Best performance
from plastic media is achieved with pressure blasting,
requiring a pressure vessel with a 60-degree conical
bottom. Refer to Clemco’s AEROLYTE cabinet line.
1.8.8 Bicarbonate of Soda: Bicarbonate of soda is
not recommended for use in standard cabinets. Bicarb is
a one-use media usually used and will quickly saturate
the filter cartridge(s). Best performance from bicarb
media is achieved with pressure blasting, requiring a
pressure vessel. Refer to Clemco’s AEROLYTE cabinet
line for cabinets that are specifically designed for use
with bicarbonate of soda.
This table offers a guideline to media type and selection based on standard 5/32" orifice air jet with 5/16" nozzle and
average conditions, such as air pressure, media/air mixture, visibility, contamination of parts being blasted, humidity,
media friability, reclaimer cleaning rate, etc. As a rule, larger nozzles deliver more media, requiring higher performance
from the reclaimer. Larger air jets and nozzles decrease the maximum mesh size of media from those recommended.
Media that is finer than those recommended may decrease visibility and carryover to the dust collector. Media coarser
than those recommended may be too dense for the reclaimer to recover from the cabinet hopper.

1.9 Compressed Air Requirements
1.9.1 The size of the compressor required to operate
the cabinet depends on the size of the air jet and blasting
pressure. Unless otherwise specified, cabinets are
supplied with a No. 5 (5/32" orifice) jet. Refer to the table
in Figure 4 to determine air consumption. Consult with a
compressor supplier for suggested compressor size
based on the air consumption. NOTE: A separate air line
is required for the reverse-pulse dust collector. If
preferred, remove the plug from the auxiliary air-port
(shown in Figure 5 and connect a 1/4″ID or larger air
line to the dust collector pulse reservoir/manifold.
Compressed Air Consumption in CFM
BNP Gun Jet Nozzle CFM PSI
No. 4 1/8" 5/16" 21 80
No. 5 5/32" 5/16" 32 80
No. 6 3/16" 3/8" 47 80
*No. 7 7/32" 7/16" 62 80
*No. 8 1/4" 1/2" 86 80
* Using this combination could affect usable media
size, refer to Section 1.8.
Figure 4
1.9.2 The air filter at the air inlet connection reduces
condensed water from the compressed air. Its use is
especially important in areas of high humidity, or when
using fine-mesh media. Moisture causes media to clump
and inhibits free flow through the feed assembly. If the
filter does not remove enough moisture to keep media
dry and flowing, it may be necessary to install an air
dryer or aftercooler in the air supply line.
1.10 Electrical Requirements
All wiring external to the cabinet is provided by the user
to comply with local electrical codes.
1.10.1 Electrical requirements depend on the size and
phase of the dust collector exhauster motor. NOTE: Full
load amps (FLA) shown below are for the motor only;
the lights draw less than one amp. Standard cabinets
are supplied as follows:
300 cfm: 1/2 HP, 115/208/230V, 1-PH, 60 HZ
115, FLA 115/7, 208/3.4, 230/3.5.

Refer to Section 2.5 to connect electrical service.
2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 Refer to Figure 1 (and Figure 2 for optional
RPC-2 dust collector) for the general arrangement.
Place all components in a convenient location where
compressed air and electrical service are available. The
cabinet location must comply with OSHA and local
safety codes. Allow for full access to all doors and
service areas, and for efficient handling of large parts.
Provide enough clearance at the dust collector for
maintenance and to remove the dust container. Place
free-standing reclaimers directly behind the cabinet with
flex hose connections and metering valve facing toward
the cabinet to allow for as few bends as possible.
Determine the best location for all components and
position them before making compressed air
connections, electrical connections, and attaching flex
hose.
2.1.2 Refer to the dust collector owner’s manual to
set up the dust collector and prepare it for operation.
2.2 Connect Conveying Hose
2.2.1 Connect the smaller diameter flex hose between
the cabinet hopper pipe adaptor and reclaimer inlet
adaptor, and connect the larger diameter hose between
the reclaimer outlet and dust collector inlet. It is easier to
slip the hose over the adaptors and create a tighter seal if
the first two or three inches of wire are removed from the
inside of the hose. Use care not to damage the hose.
Clamp flex hose securely in position with worm clamps
provided. NOTE: The hose wire helps dissipate static
electricity in the conveying hose, and also helps ground
each segment. In order for the hose wire to dissipate
static electricity, the wire must touch the metal of each
segment.
2.3 Connect Compressed Air Supply Line(s)
WARNING
Failure to observe the following before
connecting the equipment to the compressed
air source could cause serious injury from the
sudden release of compressed air.
•Lockout and tagout the compressed air supply.
•Bleed the compressed air supply line.

WARNING
To avoid the risk of injury from compressed air,
install an isolation valve and bleed-off valve
where the air supply is tapped into the
compressed air system. This enables
depressurization of the compressed-air line
before performing maintenance.
2.3.1 Refer to Paragraph 2.3.2 to determine the
recommended air supply hose size, then refer to Figure
5 and apply thread sealant to the male threads of an air
fitting that is compatible with the air supply hose fitting,
and install it onto the 1/2-NPT air filter located under the
cabinet hopper. Note that the style of connection
shown in Figure 5 is for reference only.

WARNING
If twist-on type air hose couplings are used,
they must be secured by safety pins or wires to
prevent accidental disconnection while under
pressure. Hose disconnection while under
pressure could cause serious injury.
2.3.4 Refer to the dust collector owner’s manual and
connect a compressed-air line to the pulse manifold.
2.4 Ground Cabinet
2.4.1 To prevent static electricity build up, attach an
external grounded wire from an earth ground to the
grounding lug on the left rear of the cabinet.
2.5 Connect Electrical Service
WARNING
Shorting electrical components could result in
serious electrical shocks, or equipment
damage. Electrical power must be locked out
and tagged out before performing any electrical
work. All electrical work or any work done
inside a control panel or junction box must be
performed by a qualified electrician, and
comply with applicable codes.
All wiring external to the cabinet is provided by the user
to comply with local electrical codes.
2.5.1 Single-phase wiring
2.5.1.1 Standard 300 cfm 600 cfm cabinets and dust
collectors are 115-volt single phase. Incoming power to
the cabinet is supplied by a U-ground plug; plug it into a
115-volt outlet.
WARNING
Do not use electrical adaptors that eliminate
the ground prong on 115 volt plugs. Doing so
could cause electric shock and equipment
damage.
2.5.1.2 Refer to the wiring schematic in Figure 7 and
wire the dust collector motor per instruction on the motor
data-plate, to the junction box mounted on the cabinet.
When wired as noted in Figure 7, the dust collector

2.8 Final Assembly
2.8.1 Position the foot pedal on the floor at the front of
the cabinet or on the foot shelf on ergonomic models.
2.8.2 A package of five view-window cover-lenses is
supplied with the cabinet. Install a cover lens per Section
7.3. When the cover lens becomes pitted or frosted,
replace it.
3.0 FIELD INSTALLED ACCESSORIES
Optional accessories are shown in Section 9.1
3.1 Aluminum Oxide Kit
3.1.1 An optional aluminum oxide kit is available
factory installed or may be field installed later.
Filed-installed (or replacement factory installed) kits
consist of black rubber curtains with grommets, curtain
hardware, boron carbide nozzle and light-lined flex hose.
If the existing flex hose is in good condition, reserve the
new hose for future replacement.
3.2 Curtain Installation
3.2.1 Match curtains to corresponding wall and doors.
3.2.2 Front and rear walls: Position the curtains on
the wall to be protected. Use the curtains as templates
to mark each mounting point through the grommet holes
along the upper edge of the curtain. NOTE: When laying
out the attachment points, the upper edge of the rear
curtain should be below the bottom edge of the air duct
partition. Remove the curtains, and drill a .187" (3/16")
diameter hole at each point marked. Install the curtains
using the fasteners provided (machine screw, 11/16OD
flat washer, lock washer and nut) at each grommet. The
flat washer is used between the screw head and the
rubber curtain grommet on all curtains.
3.2.3 Doors: Use protectors against the curtains and
outer doors, clamp the door curtains in place. NOTE:
When laying out the attachment points, the upper edges of
the door curtains should be even with the outer edges of
the door’s sound-proofing panel. Insert a #10 self-drilling
screw with an 11/16OD flat washer through the grommet
holes. Use a screw gun with a 5/16" socket to drill and
thread the screws through the door’s inner wall at each
grommet.
3.2.4 Ergo Side Extensions: Position the curtain on
the wall to be protected. Use the curtain as a template
and mark the top mounting point through the grommet.
Remove the curtain, and drill a .187" (3/16") diameter
hole at each point marked. Install the curtains using the
fasteners provided (machine screw, 11/16OD flat
washer, lock washer and nut) at each grommet. The flat
washer is used between the screw head and the rubber
curtain grommet on all curtains. After the curtain is hung,
mark and drill the cabinet and attach the lower
grommets in like manner.
3.3 Manometer
The optional manometer kit is listed in Section 9.1.
3.3.1 Consistent static pressure is necessary for
precise media separation, as the reclaimer's efficiency is
achieved by a centrifugal balance of air flow, particle
weight, and size. The manometer measures static
pressure. Reclaimer static pressure is set by adjusting
the dust collector damper. Refer to Section 5.4 to
adjust static pressure. Refer to Section 5.8 for
instructions on using the manometer.
3.4 Armrest
3.4.1 Assemble the armrest and mounting brackets as
shown in Figure 9.
3.4.2 Position the assembly so the armrest is about
even with the bottom of the arm-port opening. Mark one
hole location on the front of the cabinet at each mounting
bracket.
Figure 9
3.4.3 Drill a 3/8" hole at both locations and mount the
armrest using 5/16 cap screw, washers and nuts. Install
the bolts from inside the cabinet to protect the threads
from abrasion, should the armrest need to be removed
at a later date.
3.4.4 Match drill the remaining four bracket holes and
install the remaining fasteners.

raise or lower the armrest to a comfortable position.
3.5 Turntable with Workcar and Track
3.5.1 Components of the turntable and track assembly
are shown in Figure 10. The assembly consists of:
1. The inside track assembly, which is placed inside
the cabinet.
2. The hinged track extension attaches to the support
table, swings up to clear the door.
3. The track support table.
4. Turntable and workcar assembly.
Figure 10
NOTE: The track may be placed on either side of the
cabinet, allowing entry through either door. When
installing the inside track, place it so the stops are
opposite the entry door.
3.5.2 Place the inside track in the cabinet over the
existing grate as shown in Figure 11.
Figure 11
3.5.3 Position the track support table and extension as
shown in Figure 12. When the hinged extension is
lowered, the extension tracks must rest on the angled
locating supports welded to the bottom of the inside
tracks, and butt against the inside tracks.

3.5.4 Holes are provided on the track table leg pads to
permit anchoring when needed.
3.5.5 Raise the track extension to allow opening and
closing of the door.
4.0 OPERATION
4.1 Media Loading and Unloading
4.1.1 Media Loading: With the exhauster OFF, add
clean dry media, by pouring it through the reclaimer fill
door. Do not fill above the cone on the reclaimer. Do not
pour media directly into the cabinet hopper, as
overfilling may occur. Overfilling will result in media
carryover to the dust collector and possible blockage in
the conveying hose to the dust collector. Refill only after
all media has been recovered from the cabinet.
The approximate amount of media to charge the system
is as follows:
300 CFM Reclaimer .................... 50 Lb. (.5 cu. ft.) Media
600 CFM Reclaimer .................. 75 Lb. (.75 cu. ft.) Media
900 CFM Reclaimer ................... 100 Lb. (1 cu. ft.) Media
4.1.2 Media Unloading: To empty the cabinet and
reclaimer of media, blow off the cabinet interior and run
the exhauster until all media is recovered from the
cabinet. Turn OFF the exhauster, and place an empty
container under the reclaimer’s metering valve. Unscrew
the plastic plug from the metering valve, permitting

media to flow into the container. If media doesn't flow, it
has caked. Open the fill door and stir media until it starts
to flow. Replace the plug when the reclaimer is empty.
4.2 Loading and Unloading Parts
WARNING
Use solid fixturing to hold heavy parts in place.
Do not remove lift equipment until the part is
adequately supported to prevent movement.
Moving heavy, unsupported parts may cause
them to shift or topple, and cause severe injury.
This is especially important with the use of
turntables and turntables with tracks.
4.2.1 Load and unload parts through either door.
4.2.2 Parts must be free of oil, water, grease, or other
contaminants that will clump media or clog filters.
4.2.3 When blasting small parts or objects having small
pieces that could become dislodged and fall off, place an
appropriately-sized screen over the grate (or under the
grate when frequently blasting small parts) to prevent
parts from falling into the hopper.
4.2.4 Close door; the door interlock system will
prevent blasting if either door is open.
4.3 Blasting Operation
W
ARNING
Always close cabinet, reclaimer and dust
collector doors before blasting. Keep all
doors closed during blasting.
Always wear blast gloves.
Avoid pointing the blast nozzle toward the
view window.
Use the blow-off gun to blow media off parts
before opening doors.
After blasting, keep doors closed and
exhauster running until the cabinet is clear
of all airborne dust.
Stop blasting immediately if dust leaks are
detected.
4.3.1 Slowly open the air valve on the air supply hose
to the cabinet. Check for air leaks on the initial start up,
and periodically thereafter.
4.3.2 Turn ON the lights and exhauster. The on/off
switch performs both functions.
4.3.3 Load parts.
4.3.4 Close door; the door interlock system will
prevent blasting if either door is open.
4.3.5 Adjust the pilot pressure regulator to the
required blast pressure, per Section 5.1. The regulator is
located on the top, left side of the cabinet.
4.3.6 Insert hands into rubber gloves.
4.3.7 To blast, hold the gun firmly, point the gun
toward the object to be blasted, and apply pressure to
the foot pedal; blasting will begin immediately.
WARNING
Shut down the cabinet immediately if dust
discharges from the dust collector or cabinet.
Make sure the dust collector filter(s) are
correctly seated and not worn or damaged.
Prolonged breathing of any dust could result in
serious lung disease or death. Short term
ingestion of toxic dust such as lead, poses an
immediate danger to health. Toxicity and health
risk vary with type of media and dust generated
by blasting. Identify all material being removed
by blasting, and obtain a safety data sheet
(SDS) for the blast media.
NOTE: When blasting parts off the grate, use a solid
conductive back rest to support the part. Without this
assist, especially with longer blasting operations, the
operator will tire easily from resisting blast pressure, and
static electricity could build up in the ungrounded part
and cause static shocks. Whenever possible avoid
holding small parts that require blasting into the glove.
4.3.8 If an object should fall through the grate, stop
blasting immediately and retrieve it.
4.4 Stop Blasting
4.4.1 To stop blasting, remove pressure from the foot
pedal.
4.4.2 Use the blow-off gun to blow media off cleaned
parts.
4.4.3 Keep doors closed and exhauster running until
the cabinet is clear of all airborne dust.

4.4.4 Unload parts. Shut off the air supply valve, drain
the air filter, and switch OFF the lights and exhauster.
4.5 Blasting Technique
4.5.1 Blasting technique is similar to spray painting
technique. Smooth continuous strokes are most
effective. The distance from the part affects size of blast
pattern. Under normal conditions, hold the nozzle
approximately 3" to 6" from the surface of the part.
5.0 ADJUSTMENTS
5.1 Blasting Pressure
5.1.1 The pilot regulator, located on the top, left side of
the cabinet, enables the user to adjust blasting pressure
to suit the application. The suitable pressure for most
purposes is about 80 psi. Lower pressures may be
required on delicate substrates, and will reduce media
breakdown. Higher pressure may be required for difficult
blasting jobs on durable substrates, but will increase
media break down. If pressure is too high, suction in
media hose will decrease, and if high enough, cause
blow-back in the hose. Optimal production can only be
achieved when pressure is carefully monitored.
5.1.2 To adjust pressure, unlock the knob by pulling it
out as shown in Figure 13, and turn it clockwise to
increase pressure or counter-clockwise to decrease
pressure. Pressure will usually drop from closed-line
pressure when blasting starts. Once operating pressure
is set, push the knob in to lock it and maintain the
setting.
Figure 13
5.2 Air Jet Adjustment, Figure 14
5.2.1 Thread the air jet 4-1/2 to 5 full turns into the
gun body. Doing so will leave 3-1/2 to 4 threads exposed
past the lock nut. Tighten the lock nut to maintain the
setting. Refer to Section 9.3 for optional adjusting tool,
which correctly positions the jet.
Figure 14
5.3 Media/Air Mixture, Figure 15
5.3.1 Check the media stream for correct media/air
mixture; media flow should be smooth and appear as a
light mist coming from the nozzle.
5.3.2 If media does not flow smoothly, loosen the
locking nut and adjust the metering screw until the upper
holes in the metering stem are closed-off, and the lower
holes are fully open, as shown in Figure 15. This
adjustment is a starting point.
Figure 15
5.3.3 If pulsation occurs in the media hose, either
media is damp and caked, or not enough air is entering
the media stream. While blasting, loosen the locking nut
and slowly turn the adjusting screw out
(counterclockwise when viewed from the top) until media
flows smoothly. Tighten the locking nut finger-tight to
maintain the setting.
5.3.4 If media flow is too light, decrease air in the
mixture by turning the metering screw in (clockwise
when viewed from the top) covering more of the holes so

less air enters the media hose. Tighten the locking nut
finger-tight to maintain the setting.
5.4 Reclaimer Static Pressure
5.4.1 Correct static pressure varies with size of
reclaimer and the size, weight and type of media.
5.4.2 Adjust static pressure by opening (handle inline
with air flow) or closing (handle perpendicular to air flow)
the dust collector damper. Refer to the dust collector
owner’s manual, the damper is located on the inlet on
CDC-1 dust collectors, and on the exhauster outlet on
RPC and RPH dust collectors. If the damper is not
opened far enough, the reclaimer will not remove fines,
resulting in dusty media, poor visibility, and possible
media blockage in the conveying hose. If the damper is
opened too far, it may cause carryover (usable media
carried into the dust collector) and result in excessive
media consumption. Open only as far as necessary to
obtain a balance of dust removal without media
carryover.
5.4.3 A manometer is useful when adjusting or
monitoring static pressure. The manometer kit is listed
under Optional Accessories in Section 9.1. Refer to
Section 5.8 for manometer operation. The following are
static pressure starting points for given media. Static
pressure may need to be lower with finer media, higher
with coarser media. Run the media through several blast
cycles allowing the reclaimer to function with these
settings. Inspect the media in the reclaimer and fines in
the dust collector as noted in Paragraph 5.4.2. Continue
adjusting static pressure until optimum media cleaning
without carryover is attained.
Glass Bead No. 4 to 7 ................................... 3" to 3-1/2"
Glass Bead No. 8 to 13 ..................................2-1/2" to 3"
Alox. 60 & coarser ................................................ 4" to 5"
Alox. 80 & finer ...............................................2-1/2" to 3"
Steel Grit .............................................................. 6" to 7"
5.4.4 If the damper has been adjusted and carryover
or excessive dust in the media continues, the optional
adjustable vortex cylinder, available for 600 and 900
reclaimers, may help by fine-tuning media separation.
The vortex cylinder is usually required only when using
180-mesh and finer media, or lightweight media. Refer
to Section 5.5, and Accessories in Section 9.1.
5.5 Optional Externally-Adjustable Vortex
Cylinder Not available for 300 cfm reclaimer
NOTE: The externally adjustable vortex is an option
when the cabinet is provided with a CDC-1 Dust
collector. The vortex is standard with 600 cfm and 900
cfm reclaimers when the cabinet is provided from the
factory with an RPC or RPH dust collector.
The vortex cylinder fine-tunes media separation. Before
adjusting the cylinder, adjust the damper on the dust
collector to increase or decrease static pressure per
Section 5.4. Once the damper is adjusted, adjust the
cylinder.
5.5.1 The vortex cylinder is located atop the reclaimer
where the flex hose connects. Adjustments are made by
loosening the handle's tensioning knob and moving the
handle to achieve the correct setting. When the correct
setting is established, tighten the locking knob to prevent
movement. Start with the lever slightly to the right (about
one o’clock as shown in Figure 16) of the vertical
position.
5.5.2 To Remove More Fines: (Too much dust in
media) Raise the cylinder by moving the lever left toward
"COARSE", in 1/4" increments at the indicator plate.
Allow the media to go through several blast cycles
before determining if further adjustment is needed.
5.5.3 To Remove Less Fines: (Excessive usable
media is carried to the dust collector) Lower the vortex
cylinder by moving the lever right toward "FINE", in 1/4"
increments at the indicator plate. NOTE: If the cylinder is
lowered too far, the reclaimer will again begin to allow
usable media to be carried over, and cause abnormally
high static pressure.
5.5.4 When using media finer than 180-mesh, the inlet
baffle of the reclaimer may need to be removed. Refer to
Section 1.8.6.

5.6 Cabinet Air-Inlet Damper
5.6.1 Once the inlet is initially set per Section 2.6, it
seldom requires readjustment. The initial setting
produces approximately .5to .75of static pressure in
the cabinet enclosure. Do not confuse cabinet static
pressure with reclaimer static pressure, which is
controlled by the dust collector damper as noted in
Section 5.4. Reclaimer pressure must be set before
cabinet pressure.
5.6.2 Using a manometer (as noted in Section 5.8 and
listed in Section 9.1) is the most accurate method of
monitoring and adjusting cabinet pressure. Following the
instructions packed with the manometer, start the
exhauster and insert the needle into a glove, and adjust
pressure using the cabinet’s air-inlet damper. Open the
damper farther to decrease static pressure or close it
farther to increase pressure.
5.6.3 If a manometer is not available, use the gloves
as an indicator. With the exhauster ON, the gloves
should be inflated, but not elevated off the grate.
5.7 Door Interlocks, Figure 17
WARNING
Never bypass the door interlock system. Doing
so could result in injury from unexpected
blasting.
5.7.1 The door interlocks disable the blasting control
circuit when doors are open. To enable blasting, the
door interlock switches must be engaged when doors
are closed. The interlocks are set at the factory and do
not normally require field adjustment unless parts are
replaced. When adjustment is required, proceed as
follows.
5.7.2 Close cabinet doors.
5.7.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator bracket up or
down, and the adjusting screw sideways, as needed to
center the adjusting screw on the over-travel stop (in
center of detent sleeve). Tighten the bracket screws.
5.7.4 Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure
on it. Tighten the adjusting screw nuts.
5.7.5 Test the operation with the doors open and then
again closed. Point the nozzle away from the door
during the tests, and open the door only enough to
disengage the interlock switch. The interlocks should
stop the blasting when the doors are opened, and permit
blasting when the doors are closed. NOTE: Negative
pressure inside the cabinet may cause the doors to flex
inward. Tests should be performed with the exhauster
running.
Figure 17
5.8 Optional Manometer
NOTE: These instructions show several methods of taking
static pressure readings (negative pressure) on cabinet
reclaimers using a flexible tube manometer. Use the
method best suited for the application. The instruction
explains the processes for taking periodic readings and
shows how to permanently install the manometer for
taking frequent readings. Permanent fittings should be
installed when rigid ducting is used, or when the
manometer installation is permanent. Use silicone sealer
or other sealant to seal around the permanent fitting to
prevent leaks. The fitting should be capable of being
capped when the manometer tube is removed. Capping
the fitting will prevent leaks that alter the reclaimer’s
separation efficiency. The readings are reference points
so it doesn’t matter where the readings are taken as long
as they are always taken at the same location. Taking
readings at different locations could produce different
results. Static pressure readings at the door are generally
.5" to 1" lower than those taken above the reclaimer.
Adjust the screw to depress
the over-travel stop when
door is closed.

5.8.1 Refer to directions packed with the manometer
for preparation and operating instructions for the
manometer.
5.8.2 Connect one end of the 3/16" ID tubing to one of
the tubing connectors (elbow) at the top of the
manometer by pushing it over the barbed adaptor.
5.8.3 Leave the needle protector on the needle and
insert the needle into the other end of the tubing. The
ends of the tubing must fit tight on the manometer and
needle; leaks will give inaccurate readings.
5.8.4 Open both manometer valves (elbows) per the
instructions provided with the manometer.
5.8.5 Magnets on the manometer hold it in position on
the reclaimer body. The manometer must be vertically-
plumb so the fluid is level on both sides.
5.8.6 Adjust the slide rule to align the zero with the
fluid level. Refer to Figure 19.
5.8.7 Needle placement: Ref. Figure 18.
Figure 18
5.8.7.1 Taking readings in the flex hose: Remove the
needle protector, and insert the needle into the flex hose
approximately 8" from the top of the reclaimer.
5.8.7.2 Taking readings at the reclaimer door: Open
the reclaimer fill door, remove the needle protector and
place the needle so the point is inside the door opening.
Carefully close the door on the needle. The side of the
needle will embed into the rubber, creating an airtight seal.
5.8.8 Turn the exhauster ON. The negative (static)
pressure will move fluid in the tube.
NOTE: Readings must be taken with the cabinet
doors open, and with the exhauster running.
Figure 19
5.8.9 To find the static pressure, add the number of
inches the fluid travels up one column to the inches the
fluid travels down the other column. Refer to the
example in Figure 19.
8
Insert the needle into
straight section of flex
hose, about 8-inches
above the top of the
reclaimer.
The manometer must be vertical
when taking pressure readings.
Place the needle so the
point is inside the door
opening. Carefully close
the door on the needle.
With the exhauster OFF,
slide the rule to align the
zero with the fluid level.
In the example shown, fluid traveled up
the right column 1-3/4 inch,
and down the left column 1-3/4 inch.
Static pressure is determined by adding
the columns together. In the example,
the static pressure is 3-1/2 inches.
To obtain the pressure reading: With
the exhauster ON, add the number of
inches the fluid travels up the column,
to the inches the fluid travels down
the other column. The total is the
static pressure reading.
Reclaimers are for reference and
may differ from those shown.
For taking frequent readings,
install a permanent fitting in
the reclaimer wall, just below
the inner cone as shown.

5.8.10 After taking the readings, replace the needle
protector. Close the manometer valves and store the
manometer in the original container in a clean area.
NOTE: If the manometer installation is permanent, the
manometer may remain on the reclaimer body after the
valves are closed.
5.9 Foot Shelf, Ergonomic models only
5.9.1 Raise the shelf to remove pressure from the
locating pins, and remove the pins. Adjust the shelf
height and insert the pins.
6.0 PREVENTIVE MAINTENANCE
NOTE: To avoid unscheduled downtime, establish an
inspection schedule. Inspect all parts subjected to media
contact, including; the gun, nozzle, media hose, flex
hose, wear plate, plus all items covered in this section.
6.1 Daily
6.1.1 Check media level in reclaimer and refill as
necessary.
6.1.2 Check reclaimer debris screen for debris. The
screen is accessible through the reclaimer door. With
the exhauster OFF, remove the screen and empty it
daily or when loading media. Empty the screen more
often if part blasted causes excessive debris. Do not
operate the machine without the screen in place.
6.1.3 The cabinet is equipped with a manual-drain air
filter. Drain the filter at least once a day, and more often
if water is present. Moist air inhibits the flow of media.
Drain the air line and receiver tank regularly. If the filter
does not remove enough moisture to keep media dry
and flowing, it may be necessary to install an air dryer or
aftercooler in the compressed-air supply line.
6.1.4 Refer to the dust collector owner’s manual and
empty dust containers. Adjust intervals based on filling
rate.
6.1.5 Refer to the dust collector owner’s manual and
drain the pulse manifold at the end of each shift.
6.1.6 Refer to the CDC-1 dust collector manual for
pulsing instructions and pulse the cartridge at least
every half hour of blasting and before turning OFF the
exhauster. Dusty blasting conditions will require more
frequent pulsing. RPC and RPH dust collectors are
automatically pulsed at timed intervals.
6.2 Weekly
6.2.1 Inspect view window cover lens, Replace as
needed per Section 7.3.
6.2.2 Inspect gloves for wear. The first sign of
deterioration may be excessive static shocks. Replace
as needed per Section 7.1.
6.2.3 Inspect internal parts of the BNP gun for wear.
Replace parts as needed per Section 7.2.
6.2.4 Inspect flex hoses for wear.
6.2.5 During operation, inspect cabinet door seals for
media leaks.
6.2.6 Inspect the media hose for thin spots, by
pinching it every 6 to 12 inches. Replace the hose when
it becomes soft.
6.3 Monthly
6.3.1 Inspect reclaimer wear plate or rubber liners for
wear. Replace as necessary per Section 7.8 or 7.9.
6.3.2 Inspect reclaimer door gasket for wear or other
damage.
6.4 Dust Collector
Reverse-pulse dust collectors are covered in a separate
manual. Refer to Section 1.1.1.
7.0 SERVICE MAINTENANCE
7.1 Gloves
7.1.1 Special static-dissipating gloves are provided for
operator comfort. It will be necessary to change gloves
periodically as they wear. The first sign of deterioration
may be excessive static shocks.
7.1.2 Band-clamp type: Band-clamp type gloves are
held in place by metal band-clamps on the inside of the
cabinet. To replace, loosen the clamps with a
screwdriver, replace the gloves, and tighten the clamps.
7.1.3 Quick-Change type, clampless installation:
Quick-change gloves are held in place using spring rings
sewn into to the attachment end of the glove. To install,
insert the glove into the arm port, so one spring is on the
inside of the port and the other is on the outside,
sandwiching the arm port between both spring rings.

Figure 20
7.2.1 Replace the nozzle when its diameter has
increased by 1/16", or when suction diminishes
noticeably. To change the nozzle, unscrew the holding
nut from the gun end, and pull the nozzle from the gun.
Inspect the nozzle and o-ring and replace if worn or
damaged. Inspect the air jet cover replacing it before it
wears through will prolong the life of the jet. Insert a new
o-ring and nozzle, placing the tapered end of the nozzle
toward the jet. Screw the holding nut onto the gun.
7.3 View Window Cover Lens
7.3.1 Rapid frosting of the view window can be
avoided by directing ricocheting media away from the
window, and by installing a cover lens on the inside
surface of the window. Using cover lenses prolongs the
life of the view window.
7.3.2 The best way to install a cover lens is to remove
the window from the cabinet. If, for some reason, it is not
practical to remove the window, the lens may be applied
with the window glass in place.
7.3.3 To install a cover lens, carefully remove the
adhesive backing making sure the adhesive remains on
the lens, and apply the lens to the clean, dry, inner
surface of the view window. When the cover lens
becomes pitted or frosted, replace it.
7.4 View Window Replacement
WARNING
Do not use plate glass for replacement view
windows. Plate glass shatters on impact and
could cause severe injury. Use only genuine
ZERO®laminated replacement glass.
7.4.1 Remove the two window frame nuts located on
the upper edge of the window frame, and swing the
window frame open. NOTE: Ergo models are not
hinged; they are held by four frame nuts. If the frame
is to remain open, for cleaning or other reasons, remove
it per Section 7.6.
7.4.2 Remove the old window.
7.4.3 Inspect the window frame gaskets, both on the
window frame and on the cabinet. If either gasket is
damaged, replace it per section 7.5.
7.4.4 Install a view window cover lens per Section 7.3.
7.4.5 Set the new window (cover lens down) squarely
over the window opening, making sure that all edges of
the window are centered and overlapping the window
gasket, and that the window is resting on the window
support tabs.
7.4.6 Swing the window frame into place and tighten
the frame nuts.
7.5 Window Gasket Replacement, Figure 21
7.5.1 Inspect the gaskets when changing the view
window. Replace the window frame gasket and cabinet
window opening gasket at the first sign of media leakage
around the view window, or if gaskets are worn or
otherwise damaged.
7.5.2 Remove the window and window frame per
Section 7.7.

damaged.
7.7.3.6 Reassemble in reverse order.
7.8 Reclaimer Wear Plate Replacement
7.8.1 Remove the reclaimer inlet adaptor and old wear
plate. The wear plate is held in place by screws attached
from the outside of the reclaimer; remove the screws
and pull out the wear plate from the reclaimer inlet.
7.8.2 Angle the new wear plate into the reclaimer inlet
until it is in position with the straight end at the inlet.
Using a board or similar object as leverage, pry the wear
plate against the inner wall of the reclaimer. While
forcing the wear plate against the reclaimer wall, install
sheet metal screws through the old screw holes to
secure. Caulk seams between the wear plate and
reclaimer to prevent rapid wear in those areas.
7.9 Replacing or Field Installing Optional
Reclaimer Rubber Liners, Figure 25. The reclaimer
must be designed to accept liners and have a removable
top.
7.9.1 Remove the flex hoses from the reclaimer inlet
and outlet.
7.9.2 Remove the bolts and nuts, securing the
reclaimer top, and then remove the top.
7.9.3 If the reclaimer is currently unlined, proceed to
the installation note preceding Paragraph 7.9.10.
7.9.4 Remove the top liner and tube liner. NOTE: 900
cfm only (600 cfm reclaimers do not have a tube liner):
Grind the tack welds from the bottom of the tube liner
that secures the tube liner to the tube, then slide the liner
off the inner tube.
7.9.5 Remove the bolts located along the side of the
inlet, and remove the inlet baffle.
7.9.6 To remove the inlet-top liner, remove the self-
drilling screws securing it to the top of the inlet. NOTE:
600 reclaimers do not have an inlet-top liner.
7.9.7 Wall liner and inlet-side liner are held in place
with self-drilling screws. NOTE: The inlet side-liner for a
600 reclaimer is part of the wall liner, fold the strait
section for side liner inward enough to remove the liner
through the reclaimer top. From the outside of the
reclaimer, remove the screws, and remove the liner.
7.9.8 Inner cone liners and cone-ring liners are glued
onto the inner cone. Pull off the liners to remove them.
7.9.9 Remove old caulking and adhesive from the
weldment.
Installation Notes: The numbers in parentheses (-)
shown in Figure 25 and the applicable paragraphs, show
the recommended order of installation. When installing the
liners, make sure that seams are aligned. The final
assembly must be smooth and free of protrusions, edges,
and gaps. Any edges will disrupt the air flow, causing
wear, and affect the reclaimer’s media cleaning efficiency.
600 cfm only. The inlet-side and wall liner are one-
piece. To remove the wall liner the straight inlet section
must be folded inward enough to remove the liner
through the top of the reclaimer. The new liner must be
folded inward enough to insert it through the reclaimer
top. There are no inlet-top liner or tube liner on 600
reclaimers.
7.9.10 (1st) Place the cone-ring liner on the inside of
the cone-ring; check fit and trim if needed. Apply
medium-set contact cement to the fabric side and install
the liner. NOTE: Follow the instructions provided with the
adhesive. Some adhesives require it to be applied to
both contact surfaces. Smooth out the liner to eliminate
air pockets.
7.9.11 (2nd) Place the cone liner in the cone with the
fabric side down, and check the fit, trim if necessary.

Follow the instructions provided with the adhesive and
apply medium-set contact cement to the fabric side, and
install the cone liner. Smooth out the liner to eliminate air
pockets.
Figure 25
7.9.12 (3rd) Position the inlet-side liner and inlet-top
liner to make sure they fit; trimming is occasionally
required. Align the inlet-side liner and inlet-top liner and
clamp them in place. Use a self-drilling screw at each
hole location in the weldment to secure replacement
liners. NOTE: To field install new, first-time inlet-side
liner and inlet-top liners, after clamping the liners, use
self-drilling screws at each liner corner to secure them.
7.9.13 (4th) Clamp the wall liner in place, making sure it
is flush with the top of the reclaimer body and that the
cutout is aligned with the reclaimer inlet. Mark the wall
liner at the three bolt-hole locations for the inlet baffle.
Remove the liner and drill the bolt holes. Reinstall the
wall liner. Align the three bolt holes and temporarily
place bolts through the holes to hold it in place. Clamp
the liner, and while pushing the liner against the
weldment, secure replacement liners, with self-drilling
screws at each existing hole location. NOTE: To field
install a new, first-time wall liner, use self-drilling screws
to secure it at the seam and an inch or two from the top
and bottom at each quadrant. Remove the temporary
inlet baffle bolts after the liner is secured.
7.9.14 Apply silicone caulking to seal seams around the
inlet-side liner and reclaimer weldment, and between the
inlet-top liner and wall liner seam. Apply caulking at the
seams of the cone-ring liner and cone liner and between
the cone liner and wall liner. Wipe the caulking smooth.
NOTICE
All seams between each liner must be sealed,
and all seams between the liners and reclaimer
weldment must be sealed. Voids will cause
premature wear.
7.9.15 (5th) Apply adhesive-backed strip gasket to the
edge of the inlet baffle that will fit against the inner tube.
Install the inlet baffle; bolts should be installed from the
inside of the reclaimer to attach nuts from the outside.
7.9.16 (6th) Slide the top liner over the inner tube and
align the holes in the liner with those in the top. Note that
the holes around the inlet are spaced differently from the
others. Temporarily install a couple of bolts to keep the
alignment.
7.9.17 (7th) Place the tube liner over the inner tube, and
use worm clamps to temporarily clamp the liner to the
tube. NOTE: 600 cfm reclaimers do not have a tube
liner. Align it so the seam is on the backside of the
baffle, as shown in Figure 25. Make sure the tube liner is
tight against the top liner, then tack it to the bottom of the
inner tube in three or four places. Remove the clamps
when the tube liner is secured.
7.9.18 Apply caulking to the seam on the tube liner,
and between the tube liner and top liner.
7.9.19 Apply caulking around the top edge of the wall
liner and inlet-top liner.
7.9.20 Align the reclaimer top assembly and lower it
into place being careful not to smear the caulking.
Secure the top bolts and inlet baffle bolts.
7.9.21 Working through the reclaimer inlet, wipe the
caulking seal smooth. Apply additional caulking to the
seam between the baffle and wall liner. Re-caulk any
voids.
7.9.22 Install flex hoses.
7.9.23 Allow time for the caulking to cure before putting
the reclaimer in service.
