1.4 General Description
1.4.1 Aerolyte pressure 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.
Aerolyte pressure cabinets consist of four major
components:
 Cabinet Enclosure
 Reclaimer
 Blast Machine
 Dust Collector
1.4.2 Cabinet enclosure: This manual covers two
Aerolyte cabinet sizes.
6060A Approximate work chamber dimensions:
58" wide x 58.5" deep x 53" high.
7272A Approximate work chamber dimensions:
69" wide x 70.5" deep x 63" high.
1.4.3 Refer to Figure 1 for a typical arrangement and
callout of components. The overall height of an RPH-2 is
approximately 10.5 ft and 12 ft when the top access door
is open. The illustration shows the standard 900 cfm
reclaimer mounted atop the blast machine.

1.5 Theory of Operation
1.5.1 Once the components are correctly set up 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 media to
be propelled through the blast hose and out the nozzle.
After striking the object being media blasted, the blast
media, fines, dust, and byproducts generated by blasting
fall through the grate into the cabinet hopper. These
particles are then drawn into the reclaimer for
separation. Dust and fines are first separated from
reusable media and pass into the dust collector. Next,
reusable media is screened for oversize particles and
returned to the reclaimer for reuse. Dust and fines
entering the dust collector are removed from the air
stream as they pass through the filters, discharging
clean air. When the foot pedal is released, the blast
machine depressurizes and blasting stops. Media stored
in the reclaimer automatically refill the blast machine
when blast machine pressure equalizes and the pop-up
valve drops.
1.6 Blast Machine and Controls
1.6.1 Clemco certifies that its blast machines
(pressure vessels) 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 state regulations. Regulations may
include regular inspection and hydrostatic testing as
described in National Board inspection code and
jurisdictional regulations and/or laws.


Welding, grinding, or drilling on the blast
machine can weaken the vessel. Compressed-
air pressure can 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.

1.6.2 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.
1.6.3 Do not exceed the maximum working pressure
rating (PSI) of the blast machine. The maximum
pressure rating is stamped into the ASME nameplate,
which is welded to the side of the vessel.


Excessive compressed-air pressure can cause
a blast machine to rupture. To prevent serious
injury or death, do not exceed the rated
pressure of the blast machine.
1.6.4 OSHA does not require pressure-relief valves on
blast machines when air compressors supplying air to
the blast machines are built to American Society of
Mechanical Engineers Boiler and Pressure Vessel Code,
Section VIII, Division 1 and comply with OSHA
regulation 29 CFR 1910.169, which 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
with maximum pressure less than or equal to the
maximum-allowable working pressure (MAWP) stamped
on the vessel nameplate.
1.6.5 When the cabinet is set up, 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.
1.7 Dust Collector Options
1.7.1 RPH Dust Collector: An RPH-2 (900 cfm),
shown in Figure 1, is the dust collector provided with a
standard cabinet. Refer to manual number 21449.
1.7.2 HEPA (high-efficiency particulate air) Filter:
An optional HEPA afterfilter provides additional filtration
and must be used with a reverse-pulse cartridge
collector when removing toxic coatings, heavy metals, or
any other toxic materials. Refer to the applicable dust
collector manual noted in Paragraph 1.1.1 for the HEPA
option.

All dust is hazardous to breathe. Emissions
can occur from the dust collection system.
Identify all materials that are to be removed by
blasting; if any toxic materials such as lead
dust or dust from other heavy metals and
corrosives, or any other toxic materials are
being removed, use a HEPA afterfilter to assist
in maintaining inhalation hazards below the
permissible exposure limits (PELs). Prolonged
exposure to any dust can result in serious lung
disease and death. Short-term ingestion of
toxic materials can cause serious respiratory
injury or death. Filtration may not be adequate
in reducing all inhalation hazards. It remains
the employer’s or user’s responsibility to
ensure all emissions are safe to breathe.
1.8 Nozzle Options
1.8.1 Unless specified at time of purchase, cabinets
are provided with a 5/16" orifice, silicon carbide lined,
short venturi nozzle. Optional 1/4" or 3/8" orifice nozzles
are also available. 1/4" nozzles should be used only
when the air supply is limited. Low nozzle velocity and
nonaggressive media make 1/4" nozzles ineffective
except for loose adhering coatings and low production
media blasting tasks. The table in Figure 2 shows cfm
consumption when nozzles are new. Large nozzles (3/8"
and in some cases larger), should be limited to tough
stripping jobs. High nozzle velocity and high pressure will
cause rapid media breakdown.
COMPRESSED AIR CONSUMPTION *(cfm)

* 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 2
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.

1.9 Blasting Media
1.9.1 Aerolyte Dry Stripping Cabinets are designed to
utilize plastic media and other lightweight nonaggressive
reusable media specifically manufactured for dry
stripping. The usable media size range depends on the
nozzle orifice size and reclaimer cleaning rate. Several
factors affecting the reclaimer cleaning rate include:
reclaimer size, air pressure, media/air mixture, media
breakdown, contamination of parts being cleaned, and
humidity.
1.9.2 Bicarbonate of Soda: Bicarbonate of soda is
not recommended for use in plastic media blast
cabinets. Bicarb is a one-use media, which will quickly
saturate the filter cartridge(s). Refer to Clemco’s
AEROLYTE soda blast cabinet line for cabinets that
are specifically designed for use with bicarbonate of
soda.
1.10 Compressed-Air Requirements
1.10.1 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 5/16” orifice nozzle. The table in
Figure 2 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; refer to the dust collector owner’s
manual.
1.10.2 The manual-drain air filter at the blast machine
inlet removes condensed water from the compressed
air. 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.
1.11 Electrical Requirements
All wiring external to the cabinet is provided by the user
to comply with local electrical codes.
1.11.1 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:
900 cfm: 2 HP, 208/230/460V, 3 PH, 60 HZ
Supplied with 230-volt control panel unless 460-volt is
specified at the time the order is placed.
FLA 208/5.5, 230/5.6, 460/2.8.
Additional wiring information is in Section 2.11.
2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 Refer to Figure 1 for the general arrangement
and Figure 6 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 allow for as few bends as possible to prevent
wear. Determine the best location for all components
and position them before making compressed-air
connections, electrical connections, and attaching flex
hose.
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 door.
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.

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 the dust-collector owner’s manual to set
up the dust collector and prepare it for operation.

2.2 Assemble Blast Machine and Reclaimer
Figure 3


900 cfm reclaimers weigh approximately 150
lbs. When installing or removing the reclaimer,
it must be adequately supported and secured
to appropriate lift equipment. Failure to secure
and use proper lift device can result in injury.
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 upper
flange, as described in Paragraph 2.2.1.

Do not work under the reclaimer while it is
hanging from the lifting device. Severe injury or
death can occur if the reclaimer is released
before it is secured to the blast machine.
2.2.3 Use a lift, raise the reclaimer over the blast
machine assembly, and lower it in place. Attach with
fasteners provided.
Figure 3
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 until the machine can be
anchored,
2.4 Connect Conveying (flex) Hoses – Figure 4
Figure 4
2.4.1 Connect the two 4" diameter flexible conveying
hoses between the cabinet hopper transition tubes 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 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.
2.4.2 Connect the 6" diameter flex hose between the
wye pipe and reclaimer inlet adaptor. Clamp the flex
hose securely with worm clamps provided.
2.4.3 The 7" diameter hose attaches to the reclaimer

2.8 Connect Urethane Control Tubing
2.8.1 Uncoil the brown 1/8" control tubing from the
cabinet. The end of each tubing is numbered 1, 2, or 3.
Connect the tubing to the adaptor with the corresponding
number on the top of the pressure regulator, piping, and
4-way air valve. Refer to the pneumatic control
schematic in Figure 6 to confirm the connections.
2.9 Connect Compressed-Air Supply Line(s)
Figure 8
A separate air line is required for the dust-collector
pulse. Refer to the dust-collector owner’s manual.

Failure to observe the following before
connecting the equipment to the compressed-
air source can 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 8. Note that the style of connection shown in
Figure 8 is for reference only.

Hose disconnection while under pressure can
cause serious injury or death. Use safety lock
pins or safety wire to lock twist-on type air-hose
couplings together and prevent accidental
separation, and also use safety cables to
prevent hose from whipping should separation
occur. Safety lock pins and safety cables are
listed in Section 9.1: Optional Accessories.
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.

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

external grounded wire from an earth ground to the
grounding lug on the left rear of the cabinet. Refer to the
dust-collector owner’s manual and connect a ground
wire to the dust collector.
2.11 Connect Electrical Service

Shorting electrical components can result in
serious injury or death from electrical shock
and can cause 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 Three-phase wiring
A wiring schematic is stowed inside the control panel
mounted on the back of the cabinet. After wiring is
completed, keep a copy of the schematic with the
manual for future reference and for electrical
replacement parts.
2.11.1.1 Refer to the wiring schematic and wire from the
users disconnect to the panel and from the panel to the
dust-collector motor, per instruction on the motor data-
plate.
2.11.1.2 Check the dust-collector motor amperage on
initial startup. 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.
2.11.1.3 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.

Do not look into the exhauster outlet while the
paddle wheel is turning. Injury to the eye or
face can occur from objects being ejected from
the exhauster.

frosted, replace it.
3.0 FIELD INSTALLED ACCESSORIES
Optional accessories are shown in Section 9.1
3.1 Cabinet Curtains Installation – Figure 10
3.1.1
Match the curtains to the corresponding wall and
door as shown in Figure 10. Hook the curtains to the J-Hooks
welded along the top of the front, back, and sidewalls. Cut
openings for the hoses on the lower-left rear wall.
Figure 10
3.1.2 Using protectors against the curtains and outer
door, clamp the door curtains in place. The upper edges of
the door curtains should be even with the outer edges of the
soundproofing 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 attach the door curtains.
3.1.3 For front walls, place the batten strip over the
curtain and clamp it in position on the front slope above
the break, as shown in Figure 10. Match drill .187"
(3/16") diameter holes through the rubber and cabinet
front at each batten hole. To install the batten, insert
#10-24 x 1" round-head machine screws through the
cabinet front, curtain, and batten. Install lock washers
and nuts from inside the cabinet and tighten securely.
3.2 Manometer
The optional manometer kit is listed in Section 9.1.
3.2.1 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 instructions on
using the manometer.

3.4.5.1 Set the workcar on the outside track; the
grooves in the wheels are designed to ride on the top of
the track rails.
3.4.5.2 For shipping purposes, some field-installed or
replacement turntables may not be installed in the
workcar. If shipped separately, slide the turntable shaft
through the rubber bearing-protector, bearing collar, and
bearing. When the turntable shaft is fully seated in the
bearing, use a hex key to tighten the collar on the shaft.
Figure 16
3.4.5.3 Move the workcar toward the track stops until the
hole in the pin bracket is aligned with the hole in the outside-
track cross brace. Insert the release pin through both
holes to prevent the workcar from moving. Note: A similar
hole is in one of the inside-track cross braces. Inserting
the pin through the workcar and inside-track hole prevents
the workcar from moving when inside the cabinet.
3.4.5.4 When certain the tracks are aligned and level,
and that the workcar moves smoothly on all tracks,
anchor the outside track to the floor through the holes in
the footpads.
3.4.5.5 Raise the hinged track until the locking hole in
the pivot-bars is aligned with the hole in the bracket on
the bottom side of the outside hinge. Install a quick-
release pin on both sides of the track to hold it vertical.
WARNING
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

Do not pulse new dust collectors or
replacement cartridges until the cartridges are
properly seasoned, as instructed in the dust-
collector owner’s manual. Pulsing unseasoned
cartridges can decrease the efficiency of dust
collectors and cause premature cartridge
failure.
4.1 Media Loading
4.1.1 Media capacity: Media capacity is
approximately 2 cuft. 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 through
the reclaimer door. 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.
4.2 Media Unloading
4.2.1 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
per Section 4.5, and press the foot pedal. Direct media
flow into the container. Empty the container when full or
before it is too heavy to easily manage, 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.

4.3 Loading and Unloading Parts
4.3.1 Load and unload parts through the door.
4.3.2 Parts must be free of oil, water, grease, or other
contaminants that will clump media or clog filters. If parts
are oily or greasy, degrease and dry them prior to
blasting.

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.
4.3.3 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. If an object
should fall through the grate, stop blasting immediately
and retrieve it.
4.3.4 Close door; the door interlock system will
prevent blasting if door is open.
4.4 Blasting Operation


To avoid the inhalation of dust, which can
cause respiratory illness from short-term
ingestion or death from long-term ingestion:
 Use the blow-off nozzle to blow media off
parts before opening the door.
 After blasting, keep door closed and
exhauster running until the cabinet is
clear of all airborne dust.
 Always close cabinet, reclaimer, and dust-
collector doors before blasting. Keep all
doors closed during blasting.
 Always wear blast gloves.
 Stop blasting immediately if dust leaks are
detected. Refer to troubleshooting
Sections 8.14 and 8.15 and identify source
of leak.
4.4.1 Slowly open the air supply to the blast machine.
Check for air leaks on the initial startup and periodically
thereafter.
4.4.2 Turn ON the lights and exhauster. The push-
button switches located on the cabinet front performs
both functions.
4.4.3 Load parts. If parts are oily or greasy, degrease
and dry them prior to blasting.
4.4.4 Close door; the door interlock system will
prevent blasting if either door is open.
4.4.5 Insert hands into blast gloves.
4.4.6 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.

Shut down the cabinet immediately if dust
leaks are detected 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 can 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
risks 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.
4.4.7 Adjust the pilot pressure regulator to the
required blasting pressure, per Section 5.1. The
regulator is located left of the view window. NOTE:
Pressure registers on the gauge only while blasting.
When holding parts off the grate, use a solid conductive
backrest 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.
4.4.8 If an object should fall through the grate, stop
blasting immediately and retrieve it.

4.5 Operation and Function of the Choke Valve
Figure 17

Do not blast with choke valve closed or
partially closed. Prolonged blasting with the
choke valve partially closed will accelerate
wear on the metering valve.
4.5.1 Always fully open the choke valve while blasting;
open is when the handle is vertical and aligned with the
piping, as shown in Figure 17.
4.5.2 Closing the choke valve while blasting lowers
pressure in the pusher line from the pressure in the
vessel. Closing the valve forces media through the
metering valve to clear minor blockage, such as damp
media, or it is used to rapidly empty the machine to
change media.
Figure 17
4.6 Blasting Technique
4.6.1 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.
4.7 Stop Blasting
4.7.1 To stop blasting, remove foot pressure from the
top of the foot pedal. The blast machine will depressurize
each time the foot pedal is released.
4.7.2 The blast machine refills with media stored in
the reclaimer each time the foot pedal is released.
Refilling takes approximately 15 seconds.
4.7.3 Use the blow-off nozzle to blow media off parts.
4.7.4 Keep door closed and exhauster running until
the cabinet is clear of all airborne dust.
4.7.5 Unload parts.
4.8 Shutdown
4.8.1 Shut off the air-supply valve, bleed the air-supply
line, and drain the compressed-air filter and dust-
collector pulse reservoir.
4.8.2 Switch OFF the lights and exhauster.
5.0 ADJUSTMENTS
5.1 Blasting Pressure (pilot regulator)
5.1.1 The pilot pressure regulator, (located left of the
view window) 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 When 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. To adjust pressure, begin blasting and hold the
nozzle securely with the right hand. Use the left hand to
unlock the knob by pulling it out, as shown in Figure 18,
Turn it clockwise to increase pressure or counterclockwise
to decrease pressure. Once operating pressure is set,
push the knob in to lock it and maintain the setting.
NOTE: The operator may find it easier to adjust
pressure if the knob is unlocked before blasting and
when pressure is set, stop blasting to lock the knob.
5.2 Media Metering (media flow) – Figure 19
NOTE: Make media adjustments with the machine in
operation. Enlist the aid of a second person to
adjust the metering valve while the operator
operates the foot valve and holds the nozzle.
These instructions and the illustration in Figure 19 are for
a standard cabinet with FSV 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 optional valve provided.
5.2.1 Adjust media flow using the metering valve
located at the bottom of the blast machine. Begin
adjustments with the media valve closed; the valve is
closed when the handle is fully turned to either side of
center, as shown in Figure 19. To adjust, press the foot
pedal and have someone increase media flow by turning
the handle slowly toward center, no more than 1/4" at a
time. Allow time for the flow to stabilize before
readjusting. Optimum flow 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, media can be
seen as light discoloration as it exits the nozzle.
Figure 19
5.3 Reclaimer Static Pressure (dust-collector
outlet damper)
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 in line
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 exhauster
outlet on 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 maximum dust removal without good-
media carryover.
5.3.3 A manometer is useful when adjusting or
monitoring static pressure. The optional manometer kit is
listed in Section 9.1: Optional Accessories. The static
pressure starting point for plastic media and similar
media should be 2-1/2" - 3". 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.
5.3.4 If the damper has been adjusted and carryover
or excessive dust in the media continues, adjust the
vortex cylinder per Section 5.4.
5.4 Externally Adjustable Vortex Cylinder
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 5.3. 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
1 o’clock, as shown in Figure 20) 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
Handle Bolt Spacer

plate. Allow the media to go through several blast cycles
before determining if further adjustment is needed.
5.4.3 To remove fewer 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.
Figure 20
5.5 Door Interlocks – Figure 21

Never attempt to override the interlock system.
Doing so can 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 door is
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 door.
5.5.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator bracket up or
down, and the adjusting 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 door open and then
again closed. Negative pressure inside the cabinet may
cause the door to flex inward. Tests should be
performed with the exhauster running. 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 door is
opened and permit blasting when the door is closed.
Figure 21
5.6 Cabinet Air-Inlet Damper
5.6.1 Once the inlet is initially set, per Section 2.13, 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 5.3. 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, as needed to stay between .5 and .75, 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 running, the gloves
should be inflated, but not elevated off the grate.

5.7 Optional Manometer
These instructions show several methods of taking
static pressure readings (negative pressure) on
reclaimers by using a flexible-tube manometer. Use the
method best suited for the application. The instructions
explain the processes for taking periodic readings and
show how to permanently install the manometer for
taking frequent readings. A fitting should be installed
when the manometer installation is permanent; refer to
Paragraph 5.7.6.3. Use silicone or other sealant around
the fitting to prevent leaks. The fitting should be
capable of being capped when the manometer tube is
removed. A cap will prevent leaks that alter the
reclaimer’s separation efficiency. Taking readings at
different locations could produce different readings.
Static pressure readings at the door are generally 0.5"
to 1" lower than readings taken above the reclaimer.
The readings are reference points, so readings should
be taken using the same method each time the reading
is taken.
5.7.1 Refer to instructions packed with the manometer
for preparing and operating 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 cause inaccurate readings.
5.7.4 Open both manometer valves (elbows), per
manometer instructions.
5.7.5 Magnets on the manometer hold it in position on
the reclaimer or dust-collector body. The manometer
must be vertical so the fluid is level on both sides.
5.7.6 Needle placement: Figure 22 shows the
manometer setup for taking both periodic and frequent
static-pressure readings.
5.7.6.1 Taking readings in the flex hose: Remove the
needle protector and insert the needle into the flex hose,
approximately 8" above the top of the reclaimer.
5.7.6.2 Taking readings at the reclaimer door: Open
the reclaimer fill door, remove the needle protector, and
place the needle so the tip 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.
5.7.6.3 Taking frequent readings using a permanent
fitting: A permanent fitting may be installed in the
reclaimer wall, as shown in Figure 22, for taking frequent
static-pressure readings. Permanent fittings must have a
barb to accommodate the 3/16" ID tubing and have a
means of sealing the fitting when the manometer is not
in use. 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. Sealing the fitting will prevent leaks that alter
the reclaimer’s separation efficiency. Air drawn into the
reclaimer will cause carryover of good media to the dust
collector.

5.7.10 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.
6.0 PREVENTIVE MAINTENANCE

Failure to wear an approved respirator and
personal protection when servicing dust-laden
areas of the cabinet and dust collector, as well as
when emptying the container, can result in lung
disease, serious skin or eye irritation, or other
health issues. Toxicity and health risk vary with
type of media and dust generated by blasting. The
respirator must be approved for the type of dust
generated. Identify all material being removed by
blasting and obtain a safety data sheet (SDS) for
the blast media.
To avoid unscheduled downtime and to improve safety,
establish an inspection schedule. Inspect all parts
subjected to media contact, including the nozzle, blast
hose, flex hose, wear plate, and all items covered in this
section. Adjust frequency of inspections as needed,
based on:
 Usage: Frequently used cabinets require more
maintenance and inspections than those
occasionally used.
 Type of media: Aggressive media wears parts
faster than nonaggressive media.
 Condition of parts being blasted: Heavily
contaminated parts require more maintenance to
the cabinet’s media recovery system and dust
collector.
 Friable media: Media that rapidly breaks down
require more maintenance to the cabinet media
recovery system and dust collector.
6.1 Daily Inspection and Maintenance Before
Blasting with the Air OFF
6.1.1 Check media level: Check media level through
reclaimer door and refill as necessary, per Section 4.1.
6.1.2 Inspect reclaimer debris screen and door
gasket: 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. While the
door is open, inspect the door gasket for wear or
damage. Replace the gasket at the first sign of wear.
With the exhauster OFF,
slide the rule to align the
zero with the fluid level.
The manometer must be vertical
when taking pressure readings.
In the example s
hown, fluid traveled up
the right column 1-3/4"
and down the left column 1-3/4".
Static pressure is determined by adding
the reading together. In the example,
the static pressure is 3-1/2".
To find 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.

6.1.3 Drain compressed-air filter: Drain the filter 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 Inspect couplings: Make sure air hose and
blast hose couplings are secure and that lock pins and
safety cables are in place.
6.1.5 Inspect dust container: Refer to the dust-
collector owner’s manual and empty dust containers.
Adjust intervals based on filling rate.
6.2 Daily Inspection During Blasting – Have
Someone Do the Following:
6.2.1 Inspect blast-hose couplings and nozzle
holder: Inspect blast-hose couplings, coupling gaskets,
and nozzle holder for leaks.


Leaks around couplings and nozzle holders
indicate worn or loose-fitting parts. Nozzle
holders and couplings that do not fit tightly on
hose, as well as nozzles that do not fit tightly in
nozzle holders, can disconnect while under
pressure. Impact from objects (nozzles, couplings,
hoses, or media) disconnected by pressure
during operation can cause severe injury.
6.2.2 Inspect blast machine for air leaks: 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 allowed to continue, abrasive
erosion can cause extensive or irreparable
damage to the blast machine.
6.2.3 Check cabinet for dust leaks: During
operation, inspect cabinet door seals for media leaks.
Dust leaking from the inlet damper or other places on the
cabinet indicates saturated filter cartridge. Refer to the
dust-collector owner’s manual.
6.2.4 Check dust-collector exhaust air for dust:
Dust discharge at the dust-collector outlet indicates a
leaking or damaged filter cartridge. Check immediately.
Note that a small amount of dust egress is normal for a
short time before a new cartridge is seasoned.
6.2.5 Drain pulse reservoir: Refer to the dust-
collector owner’s manual and drain the pulse reservoir
(manifold) at the end of each shift.
6.2.6 Cartridge pulsing: 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-2 and RPH-2 Dust
Collectors are automatically pulsed at timed intervals.
6.3 Weekly Inspection and Maintenance Before
Blasting with Air OFF
6.3.1 Inspect view-window cover lens: Inspect
window cover lens and replace as needed, per Section
7.3.
6.3.2 Inspect gloves: Inspect gloves for wear. The
first sign of deterioration may be excessive static shocks.
Replace as needed, per Section 7.1.
6.3.3 Inspect blast hose and couplings


Worn blast hose can suddenly burst while
under blast pressure. Couplings and nozzle
holders will not safely grip worn hose and can
blow off under pressure. Compressed air and
media escaping from a burst hose, or hose
whipping from a disconnected coupling or
nozzle holder can cause severe injury.
 Inspect blast hose for wear and soft spots by
pinching it every 12 inches. Soft spots mean the
hose is worn. The first sign of wear is usually along
the outside radius where the hose bends just behind
the nozzle holder. Replace the hose as soon as soft
spots are noted.
 Make sure coupling gaskets are in good condition.
 Make sure coupling screws are fully seated in the
coupling and that none are missing.
 Make sure that safety lock pins are inserted in all
couplings.
 Make sure safety cables are attached at all blast-
hose and air-hose connections and that all slack is
removed from the cable.
6.3.4 Inspect nozzle: Remove the nozzle and inspect
nozzle for wear. Replace the nozzle when the orifice
diameter is worn 1/16" larger than original size. Before
