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
pressure cabinets consist of four major components:
1. Cabinet Enclosure
2. Reclaimer
3. Blast Machine
4. 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.
Refer to Figure 1 for arrangement of components with a
CDC-1 dust collector. Figure 2 shows the arrangement
with a RPC-2 reverse-pulse dust collector with
dust
drawer. The optional RPH-2 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 pressurizes the blast machine, causing the media
to be propelled through the blast hose and 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
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 Blast Machine and Controls
1.5.1 Clemco blast machines (pressure vessels) are
certified to conform to the ASME (American Society of
Mechanical Engineers) Boiler and Pressure Vessel
Code, Section VIII, Division 1. It is the owner’s
responsibility to maintain the integrity of the vessel in
accordance with the requirements of state regulations.
Regulations may include regular inspection and
hydrostatic testing as described in National Board
inspection code and jurisdictional regulations and /or
Laws.
WARNING
Welding, grinding, or drilling on the blast
machine could weaken the vessel. Compressed
air pressure could cause a weakened blast
machine to rupture, resulting in death or
serious injury. Welding, grinding, or drilling on
the vessel, without a National Board R stamp,
voids the Clemco ASME certification.

1.5.2 All welding repairs to the vessel must be
performed by certified welders at shops holding a
National Board R Stamp. Welding performed by any
welder not properly qualified per the ASME code voids
the Clemco ASME certification.
1.5.3 Do not exceed the maximum working pressure
rating (PSI) of the blast machine. The maximum
pressure rating is stamped into ASME nameplate which
is welded to the side of the vessel.
WARNING
Excessive compressed air pressure could
cause a blast machine to rupture. To prevent
serious injury or death, do not exceed the rated
pressure of the blast machine.
1.5.4 OSHA does not require pressure relief valves
on blast machines when air compressors supplying air
to the blast machines are built to ASME(1) code and
comply with OSHA(2) regulations. OSHA regulation
1910.169 refers to the ASME code when describing the
necessity of pressure relief valves on compressed air
equipment. DO NOT operate blast machines with air
compressors that are not equipped with properly-
functioning pressure relief valves.
(1) American Society of Mechanical Engineers, Boiler and Pressure
Vessel Code, Section VIII, Division 1,
(2) Occupational Safety and Health Administration, 29 CFR 1910, 169.
1.5.5 When the cabinet is setup, the blast machine is
ready to blast by actuating the foot pedal. Pressing the
foot pedal opens the normally closed main inlet
regulator, and closes the normally open outlet valve.
The incoming air pressurizes the blast machine, and
blasting begins. When pressure on the foot pedal is
released, the blast machine depressurizes, and blasting
stops.
1.6 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 dry filter
dust collectors for those applications.
1.6.1 CDC-1 Dust Collectors: Shown in Figure 1, the
collector is available in 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.
1.6.2 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.
1.6.3 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.
1.6.4 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.
HEPA filters are listed under Optional Accessories in
Section 9.1.
1.7 Reclaimer Options
1.7.1 Replaceable rubber reclaimer 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 1.10.4. Rubber
liners are available for 600 and 900 cfm reclaimers that

have a removable top and are designed to accept liners.
Reclaimer liners are shown in Section 9.1, Figure 30.
1.8 Nozzle Options
1.8.1 Unless otherwise specified at the time of
purchase, cabinets are shipped with a 3/16" orifice
tungsten carbide nozzle. Optional 1/8" orifice nozzles are
available for use with all cabinets, and 1/4" orifice nozzles
are for use with 900 cfm reclaimers only.
1.8.2 Nozzles with an orifice larger than those
recommended could cause air leakage from the cabinet
and impair recovery from the cabinet hopper.
1.8.3 Use boron carbide nozzles when blasting with
aggressive media, as noted in Section 1.10.4. Nozzles
lined with boron carbide extend nozzle wear life. Refer to
Optional Accessories in Section 9.1.
1.9 Metering Valve Options
1.9.1 Unless specified at the time purchase, cabinets
are supplied with a fine-mesh Sentinel metering valve.
The valve is for use with 50-mesh and finer media, and
#10 and finer glass bead. The optional Sentinel
metering valve is recommended when using media
coarser than 50-mesh. Conversions kits listed in Section
9.1 easily convert the valves.
1.10 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.
1.10.1 ZERO pressure blast cabinets utilize most
common reusable media, with the appropriate metering
valve as noted in Paragraph 1.9, specifically
manufactured for dry blasting. Media sizes listed are
guidelines only, based on standard 3/16orifice nozzle
and average conditions, such as blast pressure, media/air
mixture, visibility inside the cabinet, humidity, and
reclaimer cleaning rate. Refer to the table in Figure 3.
Several factors affecting the reclaimer cleaning rate
include: reclaimer size (cfm), blast pressure, media/air
mixture, media friability, contamination of parts being
cleaned, damper setting (static pressure), and dust
collector filter loading (differential pressure across the
filter cartridge(s).
As a rule, larger nozzles deliver more media, thus
requiring more performance from the reclaimer. When
using larger nozzles, the maximum mesh size of media
will be smaller than those normally recommended.
Using 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 for the reclaimer to recover from the
cabinet hopper.
1.10.2 Steel and Shot: Standard cabinet models
configured for steel media use are available. They include
appropriately sized conveying hose and rubber curtains to
protect the cabinet walls from peening and rapid wear.
Using 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.
1.10.3 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.
1.10.4 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, 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.
1.10.5 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.

This table offers a guideline to media selection based on standard 3/16” orifice nozzle (3/8” with plastic and
similar weight media blasting at low pressure) 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 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

Figure 3
1.10.6 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 topes, 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.
1.10.7 Plastic Media: Plastic and similar media
requires a blast machine with a 60 degree conical
bottom. Refer to Clemco’s AEROLYTE cabinet brand.
1.10.8 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). Refer to Clemco’s AEROLYTE
cabinet line for cabinets that are specifically designed for
use with bicarbonate of soda.
1.11 Compressed Air Requirements
1.11.1 The size of the compressor required to operate
the cabinet depends on the size of the nozzle and
blasting pressure. Unless otherwise specified, cabinets
are supplied with a 3/16" orifice nozzle. The table in
Figure 4 shows air consumption of nozzles when new. It
does not show the recommended compressor size. As
nozzles wear, they will consume up to 70% to 80% more
air. Consult with a compressor supplier for a suggested
compressor size based on the air consumption.
NOTE: A separate air line is required for the reverse-
pulse dust collector.
Compressed Air Consumption *(cfm)
Nozzle Air Pressure (psi)

1/8" 11 13 15 17
3/16" 26 30 33 38
1/4" 47 54 61 68
* Figures are approximate and for reference only,
and may vary for different working conditions.
Several variables, including media flow and nozzle
wear affect cfm consumption.
Figure 4
1.11.2 The air filter at the blast machine inlet removes
condensed water from the compressed air. The filter
automatically drains when moisture fills the bowl to a
certain level. Its use is especially important in areas of
high humidity, or when fine-mesh media are used.
Moisture causes media to clump and inhibits free flow
through the metering valve. 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.
1.12 Electrical Requirements
All wiring external to the cabinet is provided by the user
to comply with local electrical codes.
1.12.1 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:
600 cfm: 1 HP, 115/230V, 1-PH, 60 HZ

2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 Refer to Figure 1 (and Figure 2 for optional
reverse-pulse collector) for the general arrangement and
Figure 5 for the control line schematic. Select a 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 in front of the dust collector to remove
the dust drawer without tipping. Ideally, locate the blast
machine directly behind the cabinet with the blast hose
connection toward the cabinet. The reclaimer may be
rotated on the blast machine to make hose connections
with 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 Assemble Blast Machine and Reclaimer
2.2.1 Apply adhesive-backed strip gasket to the top of
the flange on the blast machine. Punch out an opening
at each bolt hole.
2.2.2 If the optional storage segment is used, place it
on the blast machine. The access door should be on the
bottom, and rotated to allow access to the door. Bolt into
place. Apply adhesive-backed gasket to the top flange
as described in Section 2.2.1.
2.2.3 Use a lift, raise the reclaimer over the blast
machine assembly, and lower it in place. Attach with
fasteners provided.
WARNING
Do not work under the reclaimer while it is
hanging from the lifting device. Severe injury or
death could occur if the reclaimer is released
before it is secured to the blast machine.
2.3 Support the Blast Machine
2.3.1 Use chains cables or other means to temporarily
support the blast machine and reclaimer during final
assembly.
2.4 Connect Conveying Hose
2.4.1 Connect the smaller diameter, light-lined, flexible
conveying hose between the cabinet hopper transition 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 adaptor 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 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.
2.5 Connect Blow-Off Hose
2.5.1 Attach the 1/2" blow-off hose coming from the
cabinet hopper, to the compatible fitting on the blast
machine piping, between the air filter and pressure
regulator. Refer to the schematic in Figure 5.
2.6 Connect Blast Hose
WARNING
Hose disconnection while under pressure could
cause serious injury or death. Use safety lock-
pins and safety cables on all coupling
connections to help prevent hose couplings
from accidental disconnection while under
pressure. Lock-pins and safety cables are listed
under Optional Accessories in Section 9.1.
2.6.1 Connect the blast hose from the cabinet hopper
to the coupling at the bottom of the blast machine. Make
sure coupling gaskets are in place and couplings are
secured with safety lock-pins.
2.7 Attach Blast Machine Exhaust Hose
2.7.1 Screw the male end of the exhaust hose into the
1" coupling in the hose adaptor plate, located on the
cabinet hopper, turning the hose as required. Connect
the female swivel end to the male adaptor on the blast
machine outlet valve.

2.8 Connect Urethane Control Tubing
2.8.1 Uncoil the 1/8" urethane control tubing. The end
of each tubing is numbered 1, 2 or 3. Connect the tubing
to the adaptor with the corresponding number on the
pressure regulator, piping, and 4-way air valve. Refer to
the schematic in Figure 5 to confirm the connections.
2.9 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.
2.9.1 Apply thread sealant to the male threads of an
air fitting that is compatible with the air supply hose
fitting, as noted in Section 2.9.2, and install it onto the 1-
NPT air filter located at the blast machine inlet, as
shown in Figure 6. Note that the style of connection
shown in Figure 6 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.

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 lines
before performing maintenance.
2.9.2 Install an isolation valve at the air source to
enable depressurization for service, and connect a 1" ID
or larger air line from the air source to the air filter on the
blast machine. A smaller diameter hose may reduce
blasting efficiency.
2.9.3 Refer to the dust collector owner’s manual and
connect a compressed-air line to the pulse manifold.
2.10 Ground Cabinet
2.10.1 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.
2.11 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.
2.11.1 Single-Phase Wiring
2.11.1.1 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.
2.11.1.2 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
exhauster motor will start when the cabinet light switch
is turned ON, and stop when the switch is turned OFF.
2.11.2 Three-Phase Wiring
NOTE: a wiring schematic is packed inside the cabinet’s
control panel. After wiring is completed, keep a copy of

2.11.2.2 Check the amperage on initial start up; if the
motor draws excessive amperage, gradually close the
dust collector damper, located on the inlet on CDC dust
collectors, and on the exhauster outlet on RPC and RPH
dust collectors, until the amperage is within the
specifications shown on the motor plate.
2.11.3 Check Motor Rotation
2.11.3.1 After wiring is completed, observe the warning
that follows and check the motor rotation. To check
rotation, turn the On-Off switch ON and quickly turn it
OFF, causing the motor to rotate slowly. Look through the
slots in the motor fan housing where rotation of the fan
can easily be observed. Proper rotation is indicated by
the arrow on the exhauster housing; the fan should
rotate toward the exhauster outlet. If it rotates in reverse,
change the wires as noted on the motor plate to reverse
rotation.
WARNING
Do not look into the exhauster outlet while the
paddle wheel is turning. Injury to the eye or
face could occur from objects being ejected
from the exhauster.

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 5.3 to adjust
static pressure. Refer to Section 5.7 for manometer
instructions.
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

4.0 OPERATION
4.1 Media Loading and Unloading
4.1.1 Media Capacity: Media capacity depends on
the reclaimer size. Media capacity of 600 cfm units is
approximately 1.6 cu. ft. Full capacity will be below the
opening of the pop-up valve. Capacity of 900 cfm units
is approximately 2.0 cu. ft. Full capacity is when media
is at level of the pop-up valve.
4.1.2 Media Loading: With the exhauster OFF, add
clean dry media by pouring it into the reclaimer hopper
through the reclaimer door. Do not pour media directly
into the cabinet hopper, as over filling 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.
4.1.3 Media Unloading: To empty the cabinet and
blast machine of media, turn the exhauster ON and
blow-off the cabinet interior until all media is recovered
from the cabinet. Reduce pressure to 40 psi. Place an
empty container, such as a bucket, on the cabinet grate.
Remove nozzle and nozzle washer, close the door,
close the choke valve and press the foot pedal. Direct
media flow into the container. Empty the container when
full or before it is too heavy to handle, and repeat the
process until the machine is empty. Return the choke
valve to the full open position. Clean the nozzle holder
threads and inspect the threads on the nozzle and
nozzle holder before reinstalling the nozzle washer and
nozzle. If complete purging of media is required, use a
vacuum to clean media residue in cabinet hopper and
blast machine head.
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
CAUTION
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 nozzle 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 blast machine. 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.
WARNING
Shut down the cabinet immediately if dust leaks
from the dust collector or cabinet. Make sure the
dust collector filters 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 dust
generated by blasting. Identify all material
being removed by blasting, and obtain Safety
Data Sheets (SDS) for the media.
4.3.5 Insert hands into rubber gloves.
4.3.6 To blast, hold the nozzle holder or hose just
behind the nozzle holder, point the nozzle toward the
object to be blasted, and apply pressure to the foot
pedal. Blasting will begin almost immediately.
4.3.7 Adjust the pilot pressure regulator to the
required blasting pressure, per Section 5.1. The
regulator is located on the top, left side of the cabinet.
NOTE: Pressure registers on the gauge only while
blasting.
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. The blast machine will depressurize each time
the foot pedal is released.
4.4.2 The blast machine refills with media stored in
the reclaimer each time the foot pedal is released.
Refilling takes approximately 15 seconds.
4.4.3 Use the blow-off nozzle to blow media off
cleaned parts.
4.4.4 Keep doors closed and exhauster running until
the cabinet is clear of all airborne dust.
4.4.5 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 6" from the surface of the part.

5.0 ADJUSTMENTS
5.1 Blasting Pressure
5.1.1 The pilot pressure 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 breakdown. Optimal production
can only be achieved when pressure is carefully
monitored.
5.1.2 If the application requires blasting below 40 psi,
first pressurize the blast machine at 40 psi, and then
turn the pressure to the required setting before blasting
the part. If the initial pressure is below 40 psi, the pop-up
valve may not seal.
5.1.3 Pressure registers on the gauge only while
blasting. While holding the nozzle securely, adjust air
pressure at the pilot regulator located on the top, left
side of the cabinet.
5.1.4 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. Once operating pressure is set, push in on the
knob to lock it and maintain the setting.
Figure 13
5.2 Media Metering
These instructions and the illustration in Figure 14 are
for a standard cabinet with Sentinel Metering Valve.
Optional metering valves may function differently, but
the process is similar. Refer to the metering valve
owner’s manual for the operation of the valve provided.
5.2.1 Adjust media flow using the metering valve
located at the bottom of the blast machine. The valve is
closed when the handle is fully to the right. To adjust,
begin with the valve closed, press the foot pedal and
have someone slowly move the handle to the left to
increase media flow. Allow time for the flow to stabilize
before further adjusting. The valve is fully open when the
handle is at the full left position. The optimum flow rate
depends on the type and size of media and blasting
pressure, and can best be determined by experience.
Use as little media as possible to do the job while
maintaining the best cleaning rate. Generally, with the
correct mixture, abrasive can be seen as light
discoloration as it exits the nozzle.
OPEN
CLOSE
Figure 14
5.3 Reclaimer Static Pressure
5.3.1 Correct static pressure varies with the size of
reclaimer and the size, weight and type of media.
5.3.2 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 RPC-
2 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.
5.3.3 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 5.7 for 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
5.3.2. Continue adjusting static pressure until optimum
media cleaning without carryover is attained.

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"
5.3.4 If the damper has been adjusted and carryover
or excessive dust in the media continues, the optional
adjustable vortex cylinder 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 5.4, and Accessories
in Section 9.1.
5.4 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 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.
5.4.1 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 15) of the vertical position.
5.4.2 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.
5.4.3 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.
5.4.4 When using media finer than 180-mesh, the
inlet baffle of the reclaimer may need to be removed.
Refer to Section 1.10.6.
Figure 15
5.5 Door Interlocks, Figure 16
WARNING
Never attempt to override the interlock system.
Doing so could result in injury from unexpected
blasting.
5.5.1 The door interlocks disable the blasting
control circuit when either door is open. To enable
blasting, the door interlock switch must be engaged
when the 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.
5.5.2 Close cabinet doors.
5.5.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator bracket up or
down, and the screw sideways, to center the screw on
the over-travel stop. Tighten the bracket screws.
5.5.4 Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure
on it. Tighten the adjusting screw nuts.
5.5.5 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.

5.6 Cabinet Air-Inlet Damper (cabinet static
pressure)
5.6.1 Once the inlet is initially set per Section 2.13, it
seldom requires readjustment. The initial setting
produces approximately 0.5" to 0.75" 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 5.3. Reclaimer pressure must be set before
cabinet pressure.
5.6.2 Using a manometer (as noted in Section 5.7 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 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 running, the gloves
should be inflated, but not elevated off the grate.
5.7 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 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 0.5" to 1" lower than those taken above the
reclaimer.
5.7.1 Refer to directions packed with the manometer
for preparation and operating instructions for the
manometer.
5.7.2 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.
5.7.3 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.
5.7.4 Open both manometer valves (elbows) per the
instructions provided with the manometer.
5.7.5 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.
5.7.6 Adjust the slide rule to align the zero with the
fluid level. Refer to Figure 18
5.7.7 Needle placement: Ref. Figure 17.
5.7.7.1 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.
5.7.7.2 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.
Adjust the screw to depress
the over-travel stop when
door is closed.

5.7.8 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.
5.7.9 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 18.
5.7.10 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.

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 one
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; nozzle, media hose, flex hose, in
addition to all items covered in this section. Adjust
frequency of inspections as needed based on usage,
type of media, and condition of parts being blasted.
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 Empty the compressed-air filter drain pail at
least once a day, and more often if needed. 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 Make sure that couplings are secure and lock
pins and safety cables are in place.
6.2.2 Check coupling gaskets, couplings, and nozzle
holders for leaks and wear. Replace as necessary.
6.2.3 Inspect nozzle for wear. Replace when orifice
diameter is worn 1/16” larger than original size. Replace
the nozzle washer when worn.
6.2.4 While blasting have someone inspect all
external piping, hoses, valves, and couplings for air
leaks. If leaks are found repair immediately.
6.2.5 While blasting have someone check the blast
machine for air leaks. If leaks are found around the pop-
up valve, inspection door, or pipe fittings at the bottom of
the cone, stop blasting immediately and repair or
replace worn parts. If leaks are not identified and
corrected, abrasive erosion could cause irreparable
damage to the blast machine.
6.2.6 Inspect the blast hose for wear and thin spots by
pinching it every 6 to 12 inches. Soft spots mean the
hose is worn. The first sign of wear is usually along the
outside radius where the hose bend just behind the
nozzle holder. Replace the hose as soon as soft spots
are noted. Couplings will not safely grip worn hose,
and may detach under pressure.
6.2.7 Inspect gloves for wear. The first sign of
deterioration may be excessive static shocks. Replace
as needed per Section 7.1.
6.2.8 Inspect flex hoses for wear.
6.2.9 Inspect outlet valve diaphragm: Remove the cap
four screws and inspect the diaphragm. Replace the
diaphragm if worn or cracked. Continued use with a
warn diaphragm will quickly wear the valve casting.
6.2.10 Inspect view window cover lens, Replace as
needed per Section 7.2.
6.2.11 During operation, inspect cabinet door seals for
media leaks.
6.3 Monthly
6.3.1 Inspect reclaimer wear plate or rubber liners for
wear. Replace as necessary per section 7.10 or 7.11.
6.3.2 Inspect reclaimer door gasket for 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.
7.2 View Window Cover Lens
7.2.1 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.
7.2.2 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.
7.2.3 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.
7.3 Blast Hose and Nozzle, Refer to Figure 19
7.3.1 When replacing blast hose make sure the hose
is square cut and that it is fully inserted into the nozzle
holder and coupling until it seats tightly against the
shoulder in the holder and coupling, as shown in Figure
19. Make sure correctly sized screws are used to secure
the nozzle holder and blast hose coupling. Screws
should not penetrate the inside of the blast hose.
7.3.2 Replace the nozzle when its inside diameter has
increased by 1/16", or sooner if pressure diminishes
noticeably. Make sure the nozzle washer is in good
condition and in place before screwing the nozzle into
the nozzle holder. Make sure the nozzle is screwed
tightly into the nozzle holder; if nozzle is not tight against
the nozzle washer, thread erosion will occur and nozzle
will fuse to nozzle holder.
