1.3 General Description
1.3.1 BNP abrasive 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
Refer to Figure 1 for arrangement of components using a
CDC-1 dust collector. Figure 2 shows the arrangement
with an RPC-2 (900 cfm) reverse-pulse dust collector with
dust drawer.
An optional RPH collector is set up the same way but
includes a hopper that is easier to empty and has
additional storage. Upgrading to an RPH collector may
be done at any time. The overall height of the RPH-2 is
approximately 10-feet, 4-inches, and increases to 12-ft
when the top access door is open. An RPH dust
collector is standard with systems requiring 1200 cfm
and larger dust collectors.
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. The vacuum created by
air moving through the gun draws media into the blast
gun mixing chamber. The media mixes with the air
stream 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
work table into the cabinet hoppers. 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. Do not use dust collectors with
simple cloth filters for those applications.
1.5.1 CDC-1 Dust Collectors: Shown in Figure 1,
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 CDC-1 Dust
collector manual number 28225.
1.5.2 RPC-2 Dust Collectors: Shown in Figure 2, this
collector is available in a 900 cfm model. 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 RPC manual
number 22788.
1.5.3 RPH Dust Collector: The RPH-2 is for use with
900 cfm models and RPH-3 for use with 1200 cfm
models. They are set up and operate 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
RPH 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 supplied with a No. 5 (5/32"
orifice) air jet and 5/16" orifice ceramic nozzle. Optional,
more durable tungsten carbide and boron carbide
nozzles are available and are shown under Optional
Accessories in Section 9.1 and BNP gun parts in Section
9.7. Use a boron carbide nozzles when blasting with
aggressive media, as noted in Section 1.8.4.
1.7 Reclaimer Options
1.7.1 A 900 cfm pull-thru reclaimer utilizes a CDC-1
reverse-pulse dust collector or optional RPC-2 or RPH-2
dust collector.
A 1200 cfm reclaimer utilizes a RPH-3 reverse-pulse
dust collector.
1800 cfm reclaimers are available by special order.
Refer to Figure 3 for 1800 cfm applications.
1.7.2 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. The
reclaimer must be designed to accept liners and have a
removable top. Rubber liners are shown in Section 9.1.
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: When the recovery hose diameter is
suitably sized (usually reduced one size from standard
as shown in Figure 3) steel may be used with 1200 cfm
and 1800 cfm reclaimers. When using steel media,
conveying hose should have a smooth durable lining,
and rubber curtains should be used to protect the
cabinet walls from peening and rapid wear. Cabinets
configured for steel media use can be ordered from the
factory with appropriately sized conveying hose and
curtains installed. This special requirement must be
specified at the time of purchase. They may also be field
installed at a later date. NOTE: Steel grit or shot is too
heavy to use with cabinets equipped 900 cfm
reclaimers.

This guideline to media selection is based on standard 5/16orifice nozzle (5/32air jet) and average conditions,
(air pressure, media/air mixture, visibility, contamination of parts being cleaned, humidity, media breakdown,
reclaimer cleaning rate, etc.) As a rule, larger nozzles deliver more media, requiring higher performance from the
reclaimer. Larger nozzles decrease the maximum mesh size of media from those recommended. Media that is finer
than those recommended may decrease visibility, and, at some point, carryover to the dust collector. Media coarser
than those recommended may be too dense to recover from the cabinet hopper.

Figure 3
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-lined
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.
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
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.

2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 To avoid damage, the light assembly and air
intake stack, are shipped inside the cabinet. Install the
light assembly and intake stack on the outside top of the
cabinet (ref Figure 1), using the adhesive-backed gasket
and fasteners provided. Install the light conduit and
wiring to the control panel, and wire it per the wiring
schematic packed in the panel. Refer to Section 2.5.
W
ARNING
Use an approved ladder or lift and fall
protection when installing or servicing the light
assembly or air intake stack. Do not climb on
top of the cabinet. The cabinet top will not
support body weight and could cause injury.
2.1.2 The cabinet must be placed on a flat level
surface. If the surface is not flat, the cabinet could flex,
causing the door alignment to shift. If the floor is not
level, shim the leg(s) as required to align the doors.
2.1.3 Use the eyebolts on the four top corners to lift
and maneuver the cabinet. Do not lift the cabinet from
the hopper or lower frame.
NOTICE
Do not use a forklift to lift the cabinet from the
hoppers or lower frame. The cabinet hopper is
not designed to support the weight of the
cabinet. The lower frame is designed to support
distributed weight. Using a forklift on the
hoppers or frame may cause damage.
2.1.4 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
the reclaimer directly behind the cabinet with flex hose
connection 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.
2.1.5 Refer to the dust collector owner’s manual to set
up the dust collector and prepare it for operation.

2.2 Connect Conveying Hose, Figure 5
Figure 5
2.2.1 Connect the two smallest diameter flexible
conveying hoses between the cabinet hopper transitions
and wye pipe adaptor. It is easier to slip the hose over
the adaptor and to 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. 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. Clamp
the flex hose securely with worm clamps provided.
2.2.2 Connect the intermediate diameter flex hose
between the wye pipe and reclaimer inlet adaptor. Clamp
the flex hose securely with worm clamps provided.
2.2.3 The largest diameter hose attaches to the
reclaimer outlet, which will be connected later.
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 or death
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
6 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 6 is for reference only.

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 ventilation-damper. Refer to Section
5.4 to adjust static pressure. Refer to Section 5.8 for
manometer instructions.
3.4 Armrest
3.4.1 Assemble the armrest and mounting brackets as
shown in Figure 10.
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 10
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.
3.4.5 Loosen the fasteners on the slotted bracket and
raise or lower the armrest to a comfortable position.

Always insert pins in both sides of the hinged
track to lock it upright, when it is lifted vertical.
The track could fall if left unlocked and cause
severe injury.
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 into the reclaimer hopper
through the reclaimer 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. Refill only
after all media has been recovered from the cabinet.
The minimum amount of media to charge the system is
as follows:
Reclaimer
Size
Cubic
Feet
Glass
Bead
Aluminum
Oxide
Minimum
Charge
900 cfm 1.1 100 lbs. 130 lbs. 40 lbs.
1200 cfm 1.5 135 lbs. 180 lbs. 75 lbs.
1800 cfm 2.4 215 lbs. 285 lbs. 100 lbs.
4.1.3 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
W
ARNING
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 the 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 door is open.
4.3 Blasting Operation
CAUTION
Always close cabinet, reclaimer and dust
collector doors before blasting. Keep all
doors closed during blasting.
Always use blast gloves.
Avoid pointing the blast nozzle toward the
view window.
Use the blow-off nozzle to blow media off
parts before opening the door.
After blasting, keep the door 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 push-
button switch located on the face of the control panel
performs both functions. Pull the button to start the
exhauster.
4.3.3 Load parts.
4.3.4 Close door; the door interlock system will
prevent blasting if the 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 left side of the cabinet.
4.3.6 Insert hands into 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 almost 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 nozzle to blow media off
cleaned parts.
4.4.3 Keep doors closed and exhauster running until
the cabinet is clear of all airborne dust.
4.4.3 Unload parts, shut off the air supply valve, 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 pressure regulator, located atop the
control panel of the 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 16, 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 16
5.2 Air Jet Adjustment, Figure 17
5.2.1 The air jet should be screwed 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. Loosen the lock nut
to make the adjustment and tighten the lock nut to
secure it. Refer to Figure 36, Item 16 for the optional
adjusting tool, which correctly positions the jet.
Figure 17
5.3 Media/Air Mixture, Figure 18
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 18. This
adjustment is a starting point.
Figure 18
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 the 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 ventilation 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 optional 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 and
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 - 3"
Alox. 60 & coarser ...................................................4 - 5"
Alox. 80 & finer ..................................................2-1/2 - 3"
Steel Grit ..................................................................6 - 7"
5.4.4 If the damper has been adjusted and carryover
or excessive dust in the media continues, adjusting the
vortex cylinder, may help by fine-tuning media
separation. Refer to Section 5.5 to adjust the cylinder.
5.5 Optional Externally-Adjustable Vortex Cylinder
NOTE: The externally adjustable vortex is an option
when the cabinet is provided with a CDC-1 Dust
collector. The vortex is standard with 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 vortex 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 19) 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 blast several cycles
before determining if further adjustment is needed.
5.5.3 To Remove Less Fines: (Too much 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. Run the media through
a cycle and check the dust container to determine if
further adjustment is required. 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.
Figure 19
5.5.4 When using media finer than 180-mesh, the
reclaimer inlet baffle 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 ventilation-damper
as noted in Section 5.4. Reclaimer pressure must be
set before cabinet pressure. In rare circumstances,
cabinet pressure may need to be slightly higher or lower.
5.6.2 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 further to decrease static pressure or close it
further 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 20
W
ARNING
Never attempt to override the interlock system.
Doing so could result in injury from unexpected
blasting.
5.7.1 The door interlocks disable the blasting control
circuit when the door is open. To enable blasting, the
door interlock switch must be engaged when the door is
closed. The interlocks are set at the factory and do not
usually require field adjustment unless parts are replaced.
When adjustment is required, proceed as follows.
5.7.2 Close cabinet door.
5.7.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator adjusting bracket
up or down, and the adjusting screw sideways, to center
the adjusting screw on the over-travel stop. Tighten the
bracket screws.
Figure 20
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 door open and then
again closed. Point the nozzle away from the door
during the tests, and only open the door 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.
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 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 taking 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.
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 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 22.
5.8.7 Needle placement: Ref. Figure 21.

reclaimer. The method shown for push-thru systems
may also be used.
5.8.7.2 Push-thru systems (reclaimer with exhauster):
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 21
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 22.
5.8.10 After the readings are taken, 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.
Figure 22
8
Pull-thru reclaimers only.
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.

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,
oversized byproduct from blasting could plug the nozzle.
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 7.7 or 7.8.
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

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.

7.7 Reclaimer Wear-Plate Replacement
7.7.1 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.
7.7.2 Angle the new wear plate into reclaimer inlet
until it is in position with the straight end at the reclaimer
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 seems between the wear plate and
reclaimer to prevent rapid wear in those areas.
7.8 Replacing or Field Installing Optional
Reclaimer Rubber Liners, Figure 26. The reclaimer
must be designed to accept liners and have a removable
top.
7.8.1 Remove the flex hoses from the reclaimer inlet
and outlet.
7.8.2 Remove the bolts and nuts securing the
reclaimer top, and then remove the top. Note 1800 cfm
reclaimers: The baffle and tube liner on 1800 reclaimers
are one-pierce, work from the reclaimer inlet to remove
the baffle bolts, located on the side of the inlet, before
removing the top.
7.8.3 If the reclaimer is currently unlined, proceed to
the installation note preceding Paragraph 7.8.11.
7.8.4 Grind the tack welds from the bottom of the
inner tube that secures the tube liner to the tube, then
slide the liner off the inner tube.
7.8.5 Remove the top liner and tube liner.
7.8.6 Remove the bolts located along the side of the
inlet, and remove the inlet baffle.
7.8.7 To remove the inlet-top liner, remove the self-
drilling screws securing it to the top of the inlet
7.8.8 Wall liner and inlet-side liner are held in place
with self-drilling screws. From the outside of the
reclaimer, remove the screws, and remove the liner.
7.8.9 Inner cone liners and cone-ring liners are glued
onto the inner cone. Pull off the liners to remove them.
7.8.10 Remove old caulking and adhesive from the
weldment.
Installation Notes: The numbers in parentheses (-)
shown in Figure 26 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.
7.8.11 (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.
7.8.12 (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
Pivot the frame up or down
until tension is removed

apply medium-set contact cement to the fabric side, and
install the cone liner. Smooth out the liner to eliminate air
pockets.
7.8.13 (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.
Figure 26
7.8.14 (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.
7.8.15 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.
7.8.16 (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.
NOTE: Baffle and tube liner on 1800 cfm reclaimers are
one piece.
7.8.17 (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.
7.8.18 (7th) Place the tube liner over the inner tube, and
use worm clamps to temporarily clamp the liner to the
tube. NOTE: The tube liner and baffle on 1800 cfm
reclaimers are one piece make sure the baffle bolt
locations align with those on the side of the reclaimer
inlet. Align the tube liner so the seam is on the backside
of the baffle, as shown in Figure 26. 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.
7.8.19 Apply caulking to the seam on the tube liner,
and between the tube liner and top liner.
7.8.20 Apply caulking around the top edge of the wall
liner and inlet-top liner.
7.8.21 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.
7.8.22 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.
