1.4 General Description
1.4.1 BNP tumble cabinets are intended for blasting
batches of small parts, using fixed nozzles and a rotating
barrel. The cabinet system consist of three major
components:
1. Cabinet Enclosure
2. Reclaimer
3. Dust Collector
1.4.2 Cabinet Enclosure: This manual covers the
three standard BNP tumble cabinet sizes.
The load capacity of the barrel depends on the model.
Standard cabinets are supplied as follows:
MODEL BNP-162 BNP-164 BNP-166
No. of Guns two four six
Max. volume 1 cu. ft. 2 cu. ft. 3 cu. ft.
Max. weight 100 lbs. 200 lbs. 300 lbs.
Reclaimer cfm 300 or 600 600 or 900 900
1.4.3 Reclaimer: The reclaimer is a pull-thru style,
adjustable, cyclone separator, into which air, dust, fines,
and by-products generated by the blasting process are
drawn from cabinet enclosure for separation. The
reclaimer size is determined by the cabinet size; therefore,
reclaimer sizes are not interchangeable. 300 cfm and 600
cfm reclaimers are attached to the back of the cabinet
enclosure; 900 cfm reclaimers are freestanding.
1.4.4 Dust Collector: All dust collectors used with
these tumble cabinets are pull-thru, reverse-pulse type
cartridge collectors. Dust and fines drawn from the
reclaimer are collected on the outer surface of the filter
cartridge. Refer to dust collector options in Section 1.6.
1.4.4.1 Refer to Figure 1 for arrangement of
components with a CDC-1 dust collector. The model
shown is a 164 with a 600 cfm reclaimer. Figure 2
shows a freestanding 900 cfm reclaimer connected to
an RPC-2 reverse-pulse dust collector. The optional
RPH-2 (600 cfm and 900 cfm) is set up the same way as
the RPC, but includes a hopper for additional dust
storage, and empties into a drum. The overall height of
the RPH is approximately 10-feet, 6-inches, and 12-ft
when the top access door is open. An upgraded, RPC or
RPH collector may be added at any time.
1.5 Theory of Operation
1.5.1 Once the components are correctly setup and
parts are loaded into the barrel, the air supply and
exhauster are turned ON and the cabinet door is closed.
The cabinet is readied for operation by setting the timer
on a constant speed control panel or by pulling the
sequence switch on a variable speed control panel.
Starting the timer causes air to flow through the blast
guns. Air moving through the guns draws media into the
blast gun mixing chamber. The media mixes with the air
and propels out the nozzles. As the barrel rotates, the
parts tumble in the blast stream until all parts and
surfaces are uniformly cleaned. Some of the blast media
remains in the barrel to cushion the parts as they tumble.
A portion of the blast media, along with fines, dust, and
by-products generated by blasting, flows through the
adjustable slide gates into the cabinet hopper. These
particles are drawn into the reclaimer for separation.
Lightweight dust and fines 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. Blasting
automatically stops when the timed cycle is completed.

1.6 Reverse Pulse Dust Collector Options
WARNING
Prolonged exposure to any dust could result in
serious lung disease and death. Short-term
ingestion of toxic materials, such as lead dust or
dust from other heavy metals and corrosives,
could cause serious respiratory injury or death.
Identify all materials that are to be removed by
blasting. Use reverse-pulse dust collectors with
HEPA after-filters if lead coating or any other
toxic materials are being removed by the
blasting process.
1.6.1 CDC-1 Dust Collectors: Shown in Figure 1, this
collector is available in 300, 600, and 900 cfm models.
The single filter cartridge is cleaned by using a manually-
controlled pulse of compressed air. Dust collects in a 5-
gallon dust drum, which must be frequently emptied.
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 it 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 30-gallon 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 collector when
removing lead coatings or any other toxic materials.
1.7 Nozzle Options
1.7.1 Ventilation requirements limit standard cabinets to
5/16" nozzle and No. 5 (5/32" orifice) air jets. In some
applications, where compressed air is limited, No. 4 (1/8"
orifice) air jets may be used, but blasting rates will
decrease accordingly. Refer to Section 1.9 for
compressed air requirements. Unless otherwise specified
at the time of order, cabinets are supplied with durable
boron carbide nozzles. Optional ceramic and tungsten
carbide nozzles are available for use with nonaggressive
media, and are shown under Accessories and
Replacement Parts in Sections 9.1 and 9.4. Use boron
carbide nozzles when blasting with aggressive media,
such as those listed in Section 1.8.4.
1.8 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 tumble blast cabinets utilize most
common reusable media 30-mesh to 180-mesh, that is
specifically manufactured for dry blasting (glass bead
and aluminum oxide are most commonly used). Media
sizes shown (listed under media headings) 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).
Media finer than those recommended may 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: Steel grit or shot should not be used with
standard tumble cabinets. Steel is too heavy to recover
large amount of media delivered from multiple blast
guns.
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, blast hose,
and nozzle for wear.
When using aggressive media use 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. Refer to Section 9.9.
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 (between 120 and 180 mesh.) media, the optional
adjustable vortex cylinder may help retain media. NOTE:
The adjustable vortex cylinder is standard on systems
using an RPC-2 or RPH-2 dust collector.
When using 180-mesh and finer media, the reclaimer
inlet baffle may need to be removed to retain media and
avoid carryover. Baffle removal and replacement is
easily accomplished on reclaimer models with bolt-on
removable tops. Reclaimers with welded-on tops require
grinding to remove the baffle and once it is removed, it
cannot be replaced.

BNP 162, 164 and 166 TUMBLE BLAST CABINETS Page 5

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. 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 air jet*, the number of
guns and blasting pressure. Refer to the table in Figure
3 to determine cfm requirements. 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.
Compressed Air Consumption in CFM
Model Jet Nozzles CFM PSI
162 *1/8" 2 42 80
162 5/32" 2 66 80
164 *1/8" 4 84 80
164 5/32" 4 132 80
166 *1/8" 6 126 80
166 5/32 6 198 80
*1/8" jets decrease blast rates by approximately 30%.
Figure 3
1.9.2 The air filter at the air inlet connection reduces
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 using fine-mesh media. Moisture
causes media to clot 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 of aftercooler in the air
supply line.
1.10 Electrical Requirements
All wiring external to the cabinet is provided by the user
to comply with local electrical codes.
1.10.1 Electrical requirements depend on the size and
phase of the dust collector exhauster motor and barrel
drive motor. Refer to the electrical schematic stowed in
the control panel for wiring and amps.
Refer to Section 2.6 to connect electrical service.
2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 Refer to Figure 1 (and Figure 2 for optional
RPC-2 dust collector) for the general arrangement.
Place all components in a convenient location where
compressed air and electrical service are available. The
cabinet location must comply with OSHA and local
safety codes. Allow for full access to all doors and
service areas, and for efficient handling of parts. Provide
enough clearance at the dust collector to do
maintenance and to remove the dust container. Place
freestanding reclaimers directly behind the cabinet with
flex hose connections and metering valves facing toward
the cabinet 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.
2.2 Level Cabinet Enclosure
2.2.1 Level the cabinet by using shims as necessary
under cabinet corners. A cabinet that is not level may
have problems with door closing and barrel tracking.
2.3 Connect Conveying Hose
2.3.1 Connect the smaller diameter flex hose between
the cabinet hopper pipe adaptor and reclaimer inlet
adaptor, and connect the larger diameter hose between
the reclaimer outlet and dust collector inlet. It is easier to
slip the hose over the adaptors and create a tighter seal if
the first two or three inches of wire are removed from the
inside of the hose. Use care not to damage the hose.
Clamp flex hose securely in position with worm clamps
provided. NOTE: The hose wire helps dissipate static
electricity in the conveying hose, and helps ground each

BNP 162, 164 and 166 TUMBLE BLAST CABINETS Page 6

segment. In order for the hose wire to dissipate static
electricity, the wire must touch the metal of each segment.
2.4 Connect Compressed Air Supply Line(s)
WARNING
Failure to observe the following before
connecting the equipment to the compressed
air source could cause serious injury from the
sudden release of compressed air.
•Lockout and tagout the compressed air supply.
•Bleed the compressed air supply line.
WARNING
To avoid the risk of injury from compressed air,
install an isolation valve and bleed-off valve
where the air supply it tapped into the
compressed air system. This enables
depressurization of the compressed air circuit
before performing maintenance.
2.4.1 Refer to Paragraph 2.4.2 to determine the
recommended size for the air supply hose, then refer to
Figure 4 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 air filter located on the side
of the cabinet. NOTE: the style of connection shown
in Figure 4 is for reference only. Size the couplings
and fittings no smaller than the ID of the air hose.
Figure 4
2.4.2 Connect an air line from the air source to the air
filter inlet. For best blasting performance, size the air line
as follows:
BNP-162 .................................................1" ID or larger
BNP-164 ...........................................1-1/4" ID or larger
BNP-166 ................................................1-1/2" or larger
NOTE: A separate air line is required for the optional
reverse-pulse dust collector.
WARNING
Hose disconnection while under pressure could
cause serious injury or death. Use safety lock
pins or safety wire to lock twist-on couplings
together and help prevent accidental separation,
and safety cables to prevent hose from whipping
should separation occur.
2.5 Ground Cabinet
2.5.1 To prevent static electricity build up, attach an
external grounded wire from an earth ground to the
grounding lug on the rear of the cabinet.
2.6 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.
2.6.1 Electrical requirements depend on the size and
phase of the dust collector exhauster motor and barrel
drive motor. Refer to the electrical schematic stowed
inside the control panel for wiring and amps. After wiring is
completed, keep a copy of the schematic with the manual
for future reference and for electrical replacement parts.
2.6.2 Voltage (230 or 460) is determined at time of
order. Panels are supplied with 230-volt controls unless
460-volt is specified at the time of purchase.
2.6.3 The electrician provides service from the user’s
disconnect to the electrical panel mounted on the
Air Supply Hose

cabinet and from the panel to the motor on the dust
collectors.
2.6.4 Observe the warning that follows and check the
rotation of the motors. To check, jog the exhauster
starter (momentarily turn switch ON and OFF). This will
cause the motor to rotate slowly. Look through the slots
in the fan housing on top of the motor where rotation of
the fan can easily be observed. Proper rotation of the
exhauster is indicated by the arrow on the exhauster
housing. The fan should rotate toward the scroll outlet.
The tumble barrel should rotate clockwise when viewed
from the gear reducer side.
WARNING
Do not look into the reclaimer exhauster outlet
while the paddle wheel is turning. Injury to the
eye or face could occur from objects being
ejected from the exhauster.
2.6.5 Check the dust collector motor amperage on
initial start up. If the motor draws excessive amperage,
gradually close the damper until the amperage is within
the specifications shown on the motor plate. The damper
is located on the inlet of CDC dust collectors, and on the
exhauster outlet of RPC and RPH dust collectors.
2.7 Attach Drain Tube to Air Filter, Figure 5
2.7.1 Insert a short length of 3/8" OD tubing into the
automatic drain at the bottom of the compressed-air filter
and place the other end into a pail. When the filter
automatically drains, the water will drain into the pail.
Figure 5
3.0 FIELD INSTALLED ACCESSORIES
3.1 Manometer
The optional manometer kit is listed in Section 9.1.
3.1.1 Constant static pressure is necessary for precise
media separation, as the reclaimer’s efficiency is
accomplished by a centrifugal balance of particle weight
and size. The manometer measures static pressure.
Reclaimer static pressure is set by adjusting the dust
collector damper. Refer to Section 5.4 to adjust static
pressure. Refer to Section 5.10 for instructions on
using the manometer.
3.2 Barrel Divider Kit, for BNP 164 and 166
3.2.1 Barrel dividers split the barrel chamber into
separate compartments. This permits simultaneous
blasting of different parts. Barrels should not be divided
into compartments containing less than two nozzles.

minutes. Once the timer is set, begin blasting by pushing
the "System Start" button. Blasting automatically stops
when the timer times-out. The time must be reset after
every blast cycle.
4. Barrel Jog: The exhauster must be on to
enable the switch. Pressing the momentary switch
rotates the barrel. Use it to empty the barrel of residual
media that remains in the barrel after blasting and to
position the barrel door to the front of the cabinet for
loading and unloading parts. The barrel continues to
rotate as long as pressure is maintained on the switch.
5. Door Interlock: The door interlock disables
blasting when the door is open. To enable blasting, the
door must be closed and the door interlock switch
engaged.
4.1.2 Variable speed controls, Figure 7

engaged.
6. Sequence Start: Once the timer is set (the timer
does not require resetting unless the blasting duration
changes) and the gun switch is ON, blasting starts when
the switch is pushed in. If the gun switch is OFF, all
tumble operations except blasting starts when the
system switch is engaged.
Figure 7
7. Sequence Stop: Pushing the button stops the
blast and tumble cycle. If the timed cycle was not
completed, the blast cycle will continue for the remaining
time if the sequence start button is pressed.
8. Blast Guns Switch: The switch engages and
disengages the blast guns. If the switch is toward ON,
blasting starts when the system start button is pressed.
If the switch is OFF, all tumble operations except
blasting are ON. NOTE: The barrel with continue to
rotate, which will empty abrasive from within the barrel.
Do not turn the blast guns OFF during the blast
cycle if it will cause part-on-part damage occurring
while tumbling.
9. Speed Control: Controls the rotation speed of
the tumble barrel.
Optional Media Blow-off: A blow-off timer is situated
inside the variable speed panel, but it does not operate
any controls unless the blow-off option was requested
when the cabinet was ordered. If the cabinet includes
the option, blow-off automatically begins at the end of
the blast cycle. Adjust the timer to the length of time the
blow-off is to remain ON. Blow-off automatically stops at
the end of the timed cycle. If media remains in the barrel
or on the parts after the cycle, increase blow-off time.
NOTE: If the blow-off option was not requested, set
the timer to 0 and leave it there. Because the timer is
included and wired into the circuit, the blow off option
may be added later. Refer to the wiring schematic
stowed inside the panel.

4.2 Media Loading and Unloading
4.2.1 Media Loading: With the exhauster OFF, add
clean dry media, by pouring it through the reclaimer fill
door. Do not fill above the cone on the reclaimer. Do not
pour media directly into the cabinet hopper, as
overfilling may occur. Overfilling will result in media
carryover to the dust collector and possible blockage in
the conveying hose. Refill only after all media has been
recovered from the cabinet.
The approximate amount of media to charge the system
is as follows:
300 CFM Reclaimer .................. 50 Lbs. (.5 cu. ft.) Media
600 CFM Reclaimer ................75 Lbs. (.75 cu. ft.) Media
900 CFM Reclaimer .................100 Lbs. (1 cu. ft.) Media
4.2.2 Media Unloading: To empty the cabinet and
reclaimer of media, recover all media from the cabinet,
turn OFF the exhauster and place an empty container
under the metering valve manifold (or metering valve on
162 units). Unscrew the plastic plug, permitting media to
flow into the container. If media does not flow, it has
caked. Open the fill door and stir media until it starts to
flow. Replace the plug when the reclaimer is empty.
4.3 Loading and Unloading Parts
4.3.1 Open the cabinet door, and pull the exhauster
button switch to start the exhauster. Press the barrel jog
button until the barrel-loading door is facing forward.
4.3.2 Unlatch the barrel door clamps and remove the
door.
4.3.3 Parts must be free of oil, water, grease, or other
contaminants that will cause media to clump, or clog
filters.
4.3.4 Load parts through the barrel door. Do not
overload the barrel. The following table shows maximum
load capacity in weight and cubic feet.
MODEL BNP-162 BNP-164 BNP-166
Max. volume 1 cu ft. 2 cu. ft. 3 cu. ft.
Max. weight 100 lbs. 200 lbs. 300 lbs.
4.3.5 Check gun rack blast-angle per Section 5.2.
4.3.6 Close the barrel door and latch it securely.
4.3.7 Close the cabinet door and make sure it is
latched securely. Door interlock system will prevent
blasting if door is not closed.
4.4 Blasting Operation
CAUTION
Always close cabinet, reclaimer and dust
collector doors before blasting. Keep all
doors closed during blasting.
After blasting, keep doors closed and
exhauster on until the cabinet is clear of all
airborne dust.
Stop blasting immediately if dust leaks are
detected.
4.4.1 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.
4.4.2 Turn ON the exhauster by pulling the exhauster
button.
4.4.3 Adjust the pilot pressure regulator located on the
upper, left side of the cabinet, to the required blast
pressure per Section 5.1.
4.4.4 For variable speed electrical package only, set
timer blast duration.
4.4.5 Start the blast cycle as follows:
Constant Speed Electrical Package:
1. Set timer for blast duration. Blasting begins when
timer is set.
Variable Speed Electrical Package:
1. Set Speed Control
2. Pull Gun Switch ON
3. Pull Sequence Switch ON
WARNING
Shut down the cabinet immediately if dust
discharges from the cabinet or dust collector.
Make sure that the filter cartridge(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 SDS safety data sheet
for the blast media.
4.4.6 Check media flow per Section 5.3.

4.5 Stop Blasting
4.5.1 Blasting and barrel rotation stop when the timer
cycle is complete.
4.5.2 Allow exhauster to run awhile before opening the
door; do not turn off exhauster until parts are unloaded.
4.5.3 Press the barrel jog button until the barrel-
loading door is facing forward, then completely remove
the barrel door.
4.5.4 Unloaded parts through the barrel door, or jog
the barrel until parts empty into the parts tray.
4.5.5 Remove parts from the tray. The parts tray may
be installed with the open end toward the front or back,
place it to most easily handle the parts.
4.5.6 Reload the barrel, or shut off the air supply
valve, drain the air filter, and switch OFF the exhauster.
5.0 ADJUSTMENTS
5.1 Blasting Pressure, Figure 8
5.1.1 The pilot regulator, located on the upper left side
of the cabinet, enables the user to adjust blast 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. If pressure is too high,
suction in media hose will decrease, and if high enough,
cause blow-back in the hose. In all cases, optimal
production can only be achieved when pressure is
carefully monitored.
Figure 8
5.1.2 To adjust, unlock the knob, and turn it clockwise
to increase pressure or counterclockwise to decrease
pressure. Pressure will usually drop from closed-line
pressure when blasting starts. Once operating pressure
is reached, lock the knob to maintain the setting
5.2 Gun Rack Blast Angle, Figure 9
NOTICE
The gun rack must be adjusted to direct the
blast stream toward the parts. If the rack is not
correctly adjusted, the tumble barrel will wear
prematurely and parts will require longer blast
cycles.
5.2.1 Load parts into the barrel; close the barrel door;
and jog the barrel until it has rotated one revolution. This
places the parts at the angle in which they tumble.
5.2.2 Open the door and check the alignment of the
guns by placing a dowel, pencil, or similar object into a
nozzle.
5.2.3 If the guns do not point toward the center of the
parts, loosen the three gun rack hold-down brackets and
rotate the rack until the nozzles point to the center of the
parts.
5.2.4 Remove the dowel and tighten the hold-down
brackets to maintain the setting.

5.3 Media/Air Mixture, Figure 10
5.3.1 Media should flow smoothly and evenly through
the hoses. Flow can be observed through the clear
metering valve body.
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. Refer to Figure 10. This
adjustment is a starting point.
Figure 10
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 damper. Refer to the dust collector
owner’s manual; the damper is located on the inlet on
CDC-1 dust collectors, and on the exhauster outlet on
RPC and RPH dust collectors. If the damper is not
opened far enough, the reclaimer will not remove fines,
resulting in dusty media, poor visibility, and possible
media blockage in the conveying hose. If the damper is
opened too far, it may cause carryover (usable media
carried into the dust collector) and result in excessive
media consumption. Open only as far as necessary to
obtain a balance of dust removal without media carryover.
5.4.3 A manometer is useful when adjusting or
monitoring static pressure. The manometer kit is listed
under Optional Accessories in Section 9.1. Refer to
Section 5.10 for manometer operation. The following are
static pressure starting points for given media. Static
pressure may need to be lower with finer media, higher
with coarser media. Run the media through several blast
cycles allowing the reclaimer to function with these
settings. Inspect the media in the reclaimer and fines in
the dust collector as noted in Paragraph 5.4.2. Continue
adjusting static pressure until optimum media cleaning
without carryover is attained.
Glass Bead No. 4 to 7 .................................. 3" to 3-1/2"
Glass Bead No. 8 to 13 .....................................2-1/2 - 3"
Alox. 60 & coarser ...................................................4 - 5"
Alox. 80 & finer ..................................................2-1/2 - 3"
5.4.4 If the damper has been adjusted and carryover
or excessive dust in the media continues, an optional
adjustable vortex cylinder, (standard on pull through
reclaimers), may help retain media. This option is
usually required only when using 200 mesh and finer
media, or lightweight media. See Section 5.5, and
reclaimer accessories in Section 9.10 (600 cfm) or 9.11
(900 cfm).
5.5 Optional Externally-Adjustable Vortex
Cylinder Figure 11, Not available for 300 cfm reclaimer
NOTE: The externally-adjustable vortex is an option
when the cabinet is provided with a CDC-1 Dust
collector. The vortex is standard with 600 cfm and 900
cfm reclaimers when the cabinet is provided from the
factory with an RPC or RPH dust collector.
The vortex cylinder fine-tunes media separation. Before
adjusting the cylinder, adjust the damper on the dust
collector to increase or decrease static pressure per
Section 5.4. Once the damper is adjusted, adjust the
cylinder.
5.5.1 The vortex cylinder is located atop the reclaimer
where the flex hose connects. Adjustments are made by
loosening the handle's tensioning knob and moving the
handle to achieve the correct setting. When the correct
setting is established, tighten the locking knob to prevent
movement. Start with the lever slightly to the right (about
one o’clock as shown in Figure 11) of the vertical position.
5.5.2 To Remove More Fines: (Too much dust in
media) Raise the cylinder by moving the lever left toward
"COARSE", in 1/4" increments at the indicator plate.
Allow the media to go through several blast cycles
before determining if further adjustment is needed.

5.5.3 To Remove Less Fines: (Excessive usable
media is carried to the dust collector) Lower the vortex
cylinder by moving the lever right toward "FINE", in 1/4"
increments at the indicator plate. NOTE: If the cylinder is
lowered too far, the reclaimer will again begin to allow
usable media to be carried over, and cause abnormally
high static pressure.
5.5.4 When using media finer than 180-mesh, the inlet
baffle of the reclaimer may need to be removed. Refer to
Section 1.8.6.
Figure 11
5.6 Door Interlocks, Figure 12
WARNING
Never attempt to override the interlock system.
Doing so could result in injury from unexpected
blasting.
5.6.1 The door interlock disables 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 interlock is set at the factory and does not
usually require field adjustment unless parts are replaced.
When adjustment is required, proceed as follows.
5.6.2 Close cabinet door.
5.6.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator bracket up or
down, and the adjusting screw sideways, to center the
adjusting screw on the switch button. Tighten the
bracket screws.
5.6.4 Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure
on it. Tighten the adjusting screw nuts.
Figure 12
5.6.5 Test the operation with the door open only
enough to disengage the interlock switch, and then
again with the door closed. The interlock should stop the
blasting when the door is opened, and permit blasting
when the door is closed. NOTE: Negative pressure
inside the cabinet may cause the door to flex inward.
Tests should be performed with the exhauster running.
5.7 Tumble Barrel Slide Doors, Figure 13
5.7.1 The barrel must retain an amount of media to
cushion parts as they tumble. The two slide doors
control the amount of media retained in the barrel.

5.7.2 How far the slide doors are open depend, on the
parts and media size. Begin with the door set to allow a
small amount of media to fall through the holes as the
barrel turns.
5.7.3 After a short blast cycle, open the barrel-loading
door to see how much media is retained in the barrel
and if the parts are nicked from part-on-part
impingement. Adjust the opening size accordingly.
5.8 Timer, Blast Duration
Refer to Section 4.1.1 for constant speed controls
Refer to Section 4.1.2 for variable speed controls
5.8.1 Set the timer for the duration of the blast cycle.
Blasting automatically stops when the timer times out.
Trial and error will determine the timer setting for the
most favorable results. After the part is correctly
processed, make a NOTE: of the total blast time for
future runs of similar parts.
5.8.2 Timers in constant-speed electrical panels
require resetting after each cycle. The variable speed
timer does not require resetting unless the blasting
duration changes.
5.9 Speed Control,Barrel: Refer to Section 4.1.2.
Available with variable speed electrical package only.
5.9.1 Set the speed control to rotate the barrel for
optimum speed for processing the parts. Trial and error
will determine the optimum speed setting. If multiple
types of parts are processed using different speeds,
make a NOTE: of the speed for future runs of similar
parts.
5.10 Optional Manometer
NOTE: These instructions show several methods of
taking static pressure readings (negative pressure) on
Pulsar reclaimers, by 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 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. This 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 .5" to 1" lower than those taken above the
reclaimer. The readings are reference points, so
readings should be taken using the same method each
time the reading is taken.
5.10.1 Refer to instructions packed with the manometer
for preparation and operating of the manometer.
5.10.2 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.
5.10.3 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.
5.10.4 Open both manometer valves (elbows) per the
instructions provided with the manometer.
5.10.5 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.
5.10.6 Needle placement: The illustration in Figure 14
shows the manometer set-up for taking both periodic
and frequent static pressure readings.
5.10.6.1 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.
5.10.6.2 Taking readings at the reclaimer door: Open
the reclaimer fill door, remove the needle protector, and
place the needle so the point is inside the door opening.
Carefully close the door on the needle. The side of the
needle will embed into the rubber, creating an airtight
seal.
5.10.6.3 Taking frequent readings using a permanent
fitting: A permanent fitting may be installed in the
reclaimer wall as shown in Figure 14 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.

5.10.7 Adjust the slide rule to align the zero with the
fluid level. Refer to Figure 15.
5.10.8 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.
5.10.9 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 15.
Figure 15
5.10.10 After the 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
NOTE: To avoid unscheduled downtime, establish a
weekly inspection schedule. Inspect all parts subjected
to media contact, including: the gun, nozzles, media
hose, flex hose, reclaimer wear plate, in addition to all
items covered in this section.
6.1 Daily Maintenance
6.1.1 Check media level in reclaimer and refill as
necessary.
6.1,2 Check reclaimer 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 Moist air inhibits the flow of abrasive. Empty the
compressed-air filter drain container. The cabinet is
equipped with an auto-drain air filter. By inserting a short
length of 3/8" O.D. tubing into the automatic drain at the
bottom of the filter and placing the other end into a pail,
the filter automatically drains the water into the pail.
Empty the pail at least daily and while it is manageable.
NOTE: If the filter does not remove enough moisture to
keep abrasive 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; pulse the cartridge at least every
half hour of blasting and before turning OFF the
exhauster. Dusty blasting conditions will require more
frequent pulsing. Alternate RPC and RPH dust collectors
are automatically pulsed at timed intervals.
6.2 Weekly Maintenance
6.2.1 Inspect nozzles and gun bodies for wear as
noted in Section 7.1, Replace nozzle when orifice
diameter is worn 1/16" larger than original size, or when
suction diminishes noticeably.
6.2.2 During operation, inspect cabinet door seals for
media leaks.
6.2.3 Inspect flex hoses for wear.
6.2.4 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 Maintenance
6.3.1 Inspect reclaimer wear plate or rubber liners for
wear. Replace as necessary.
6.3.2 Inspect reclaimer door gasket for wear or
damage.
6.3.3 Inspect the barrel liners for wear. Replace the
liners as soon as the rubber is worn to the metal
substrate

7.6 Replacing or Field Installing Optional
Reclaimer Liners, Figure 19. Available for 600 and 900
cfm reclaimers. The reclaimer must be designed to
accept liners and have a bolt-on, removable top.
7.6.1 Remove inlet and outlet flex hoses, inlet adaptor
pipe adaptor, and inlet gasket.
7.6.2 900 cfm only: Remove the screws that secure
the inlet-top liner to the inlet and remove the top liner.
NOTE: 600 reclaimer does not have an inlet top-liner.
7.6.3 Remove the bolts securing the reclaimer top and
remove the top, along with the top liner and tube (inner
cylinder) liner. NOTE: 600 reclaimer does not have a
tube liner.
7.6.4 Place the top assembly upside down (top liner
and tube liner on 900 cfm side up) on a bench.
7.6.5 900 cfm only: Note the location of the tube liner
seam and mark the inner tube at the seam. (When the
new tube liner is installed, the seam must be positioned
at the same location). Grind the spot welds holding the
tube liner to the inner tube and remove the liner by
sliding it off the tube.
7.6.6 Remove the top liner by sliding it off the inner
tube.

7.6.7 Remove the three vertical nuts and bolts
(located next to the reclaimer inlet), which hold the inlet
baffle, and remove the baffle.
7.6.8 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 liners
through the reclaimer top). NOTE: The inlet side-liner for
a 600 reclaimer is an extension of the wall liner. Fold the
strait extension inward enough to remove the liner.
7.6.9 Cone liners and cone ring liners are glued onto
the inner cone. Pull the liners to remove them.
7.6.10 Remove remnants of old caulking and adhesive
from the weldment.
Figure 19
Installation Note: The numbers in parenthesis (-) shown
in Figure 19 and the applicable paragraph, show the
recommend order of installation. When installing 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.
7.6.11 (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.
7.6.12 (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
apply medium-set contact cement to the fabric side, and
install the cone liner. Smooth out the liner to eliminate air
pockets.
7.6.13 (3rd) Wall Liners: Install wall liner through the
reclaimer top. NOTE: The inlet side-liner for a 600
reclaimer is an extension of the wall liner. Fold the strait
extension inward enough to install the liner. Clamp the
wall liner in place (including the straight inlet extension
of the 600 liner), making sure it is flush with the top
of the reclaimer body and aligned with the inlet.
Match drill the wall liner at the three bolt-hole locations
for the inlet baffle. Temporarily place bolts through the
holes to hold it in place. While pushing the liner against
the weldment, secure it with self-drilling screws, through
each screw hole in the weldment. Remove the
temporary inlet baffle bolts and clamps after the liner is
secured.
7.6.14 (4th) 900 cfm only: Position the inlet side-liner
and inlet top-liner to make sure they fit. Trimming is
occasionally required. Align the liners and clamp them in
place. Use self-drilling screws at each hole location in
the weldment to secure the liners.
7.6.15 (5th) Install the inlet baffle; install bolts from the
inside of the reclaimer to attach nuts from the outside.
7.6.16 Use RTV silicone caulking, included with liner
sets, 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, between the cone liner and wall
liner, wall liner and baffle, and the seam in the 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.
7.6.17 (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 them
aligned.
