1.3 General Description
1.3.1 Refer to Figure 1 for arrangement of components.
The blast cabinet encloses 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. Pulsar® 55se cabinets consist of two
major components.
1. Cabinet Enclosure
2. Pulsar III 300 CFM Power Module is attached to the
back of the cabinet enclosure and includes:
• 300 cfm reclaimer
• 300 cfm reverse-pulse cartridge dust collector
1.4 Theory of Operation
1.4.1 Once the cabinet is correctly setup and turned
ON, the cabinet is ready for operation by actuation of the
foot pedal. Fully pressing down on the foot pedal causes
air to flow through the blast gun. The vacuum created by
air moving through the gun draws media into the blast
gun mixing chamber. The media mixes with the air and
is propelled out the nozzle. After striking the object being
blasted, the blast media, fines, dust, and by-products
generated by blasting, fall through the mesh work table
into the cabinet 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, the media is screened for oversize
particles, and returned to the reclaimer hopper 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,
blasting stops.
1.4.2 The dust collector filter cartridge is cleaned by a
pulse of high velocity compressed air expanding against
the inner surface of the cartridge. The expanding air
momentarily reverses air flow through the cartridge to
release dust accumulated on the outer surface. The dust
particles fall away from the cartridge and into the hopper
for removal. The pulse occurs each time the foot pedal
is pressed or released.

Figure 1
1.5 HEPA (high efficiency particulate air) Filter
1.5.1 Optional HEPA after-filter provides additional
filtration. A HEPA filter must be used when removing
lead coatings or any other toxic materials. HEPA filter is
listed under Optional Accessories in Section 9.1.
1.6 Nozzle Options
1.6.1 Unless otherwise specified at the time of order,
cabinets are shipped with a 5/16" orifice ceramic nozzle
and No. 5 (5/32" orifice) air jet. Optional, more durable
tungsten carbide and boron carbide nozzles are
available and are listed under Optional Accessories in
Sections 9.1 and 9.3. Use boron carbide nozzles when
blasting with aggressive media, as noted in Section
1.7.4
1.7 Blasting Media
1.7.1 The Pulsar® 55se cabinet utilizes most common
reusable media between 60-mesh and 180-mesh that is
specifically manufactured for dry blasting. Media sizes
shown are guidelines only, based on standard (5/16"
orifice) nozzle (5/32" air jet) 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), blast pressure, media/air
mixture, media friability, contamination of parts being
cleaned, damper setting (static pressure), type of dust
collector, dust collector filter loading (differential
pressure across the dust filters).

As a rule, larger air jets and nozzles deliver more media,
thus requiring more performance from the reclaimer.
Therefore, larger nozzles decrease the maximum mesh
size of media from those normally recommended. On
the other hand, leaner media flow and lighter or less
dense media may increase the maximum usable media
size. Media finer than those recommended may
decrease visibility, and increase carryover to the dust
collector. Media coarser than those recommended may
be too dense for the reclaimer to recover from the
cabinet hopper.
1.7.2 Steel: Steel grit or shot should not be used with
the Pulsar® 55se cabinet. The cabinet is too small to
prevent peening of the cabinet weldment, and the
reclaimer is too small to efficiently convey ferrous,
metallic media.
1.7.3 Sand and Slag: Sand should NEVER be used
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.
1.7.4 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 equipment components
exposed to the media will be reduced. To avoid
unscheduled down time, periodically inspect the
reclaimer wear plate, exhauster housing and paddle
wheel, blast hose, and nozzle for wear.
When using aggressive media, install an optional
aluminum oxide kit. The kit includes rubber curtains for
the cabinet interior and a boron carbide lined nozzle.
Nozzles lined with boron carbide extend nozzle wear life.
See Optional Accessories in Section 9.1
1.7.5 Glass Bead: No. 6 to No. 12 glass bead are
recommended for the Pulsar® 55se. Most beads are
treated to ensure free-flow operation even under
moderately high-humidity conditions. Glass beads
subjected to excessive moisture may be reused after
thorough drying and breaking up of any clumps.
1.7.6 Plastic Media: Plastic and similar lightweight
media are generally not recommended in suction style
cabinets. Plastic media blasting usually requires a blast
machine with a 60-degree conical bottom. Refer to
Clemco’s AEROLYTE brand.
1.8 Compressed Air Requirements
1.8.1 The size of the compressor required to operate
the cabinet depends on the size of the air jet and
blasting
pressure. Unless otherwise specified, cabinets are
supplied with a No. 5 (5/32" orifice) jet. Refer to the table
in Figure 2 to determine cfm requirements. Consult with
a compressor supplier for suggested compressor size
based on the maximum air consumption.
Air Consumption in cfm
BNP Gun Jet Nozzle CFM PSI
No. 4 1/8" 5/16" 21 80
No. 5 5/32" 5/16" 32 80
*No. 6 3/16" 3/8" 47 80
* Using a No.6 jet and nozzle in applications that
produce excessive dust may cause poor visibility.
The 300 cfm reclaimer may not recover heavy,
coarse abrasive from the cabinet hopper when
using a No. 6 jet and nozzle combination.
Figure 2
1.8.2 The air filter at the air inlet connection reduces
condensed water from the compressed air. Its use is
especially important in areas of high humidity, or when
fine-mesh media are used. Moisture causes media to
clump and inhibits free flow through the feed assembly.
If the filter does not remove enough moisture to keep
media dry and flowing, it may be necessary to install an
air dryer or aftercooler in the air supply line.
1.9 Electrical Requirements
1.9.1 Electrical requirements depend on the size and
phase of the motor. Standard cabinets are supplied with
300 cfm reclaimer, using 1/2 HP, 115/230V, 1-PH, 60
HZ motors, wired for 115 volts.
1.9.2 A power cord with u-ground plug is provided.
2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 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 parts. Make sure there is room to
load media and to remove spent media. Determine the
best location, and position the unit before making final
connections.

Minimum compressed air line ID Figure 3
WARNING
Failure to observe the following before
connecting the equipment to the compressed
air source could cause serious injury or death
from the sudden release of compressed air.
Lockout and tagout the compressed air supply.
Bleed the compressed air supply line.
WARNING
To avoid the risk of injury from compressed air,
install an isolation valve and bleed-off valve
where the air supply is tapped into the
compressed air system. This enables
depressurization of the compressed-air line
before performing maintenance.
2.2.3 Install an isolation valve at the air source to
enable depressurization for service, and connect an air
line from the air source to the filter inlet located under
the cabinet hopper.
WARNING
If twist-on type air hose couplings are used,
they must be secured by safety lock pins or
wires to prevent accidental disconnection while
under pressure. Hose disconnection while
under pressure could cause serious injury.
2.3 Ground Cabinet
2.3.1 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 power module.
2.4 Connect Electrical Service
2.4.1 Power is supplied by a u-ground plug; plug it
into 115-volt outlet.
WARNING
Do not use electrical adaptors that eliminate the
ground prong on 115 volt plugs. Doing so could
cause electric shock and equipment damage.
2.5 Inlet Damper
2.5.1 The inlet damper must be set to match the
cabinet dimensions and reclaimer size. The decal on the
damper shows the settings in degrees. For the initial
setting, align the handle to 30 degrees. Refer to Section
5.7 for adjustment procedure.
2.5.2 Loosen the lock nuts and position the damper.
When correctly positioned, tighten the lock nuts to
maintain the setting.
2.6 Position the foot pedal on the foot shelf or on the
floor at the front of the cabinet. The foot shelf is easily
removed by removing the two release pins.
2.7 Window Cover Lens
2.7.1 A package of 5 cover lenses is supplied with the
cabinet. To install a cover lens, remove the adhesive
backing and apply the lens to the clean, dry, inner
surface of the view window per Section 6.6. When the
cover lens becomes pitted or frosted, replace it.
3.0 FIELD INSTALLED ACCESSORIES
3.1 Alox (aggressive media) Kit

NOTE: Wear plates and lined flex hose are standard on
current cabinets. Inspect both items and if either
requires replacement order separately, refer to:
Section 9.2, Figure 26, Item 15 for flex hose
Section 9.8, Figure 32, Item 11 for wear plate.
3.2 Curtain Installation
3.2.1 Match curtains to corresponding wall and doors.
3.2.2 Front and rear walls: Position the curtain on
the wall to be protected. Using the curtains as templates,
mark each mounting point through the grommet holes
along the upper edge of the curtain. NOTE: When laying
out the attachment points, the upper edge of the rear
curtain should be below the bottom edge of the air duct
partition. Remove the curtains, and drill a .187" (3/16")
diameter hole at each point marked. Install the curtains
using the fasteners provided (machine screw, 11/16OD
flat washer, lock washer and nut) at each grommet. The
flat washer is used between the screw head and the
rubber curtain grommet on all curtains.
3.2.3 Doors: Using protectors against the curtains
and outer doors, clamp the door curtains in place.
NOTE: When laying out the attachment points, the upper
edges of the door curtains should be even with the outer
edges of the door’s sound proofing panel. Insert a #10
self-drilling screw with an 11/16" OD flat washer through
the grommet holes. Use a screw gun with a 5/16" socket
to drill and thread the screws through the door’s inner
wall at each grommet.
3.3 Track and Low Profile Table,
Maximum Weight Capacity 500 Lbs.
3.3.1 Components of track and table assembly are
shown in Figure 4. The assembly consists of:
1. Track assembly: mounts inside the cabinet.
2. Table assembly: rollers on sliding table fit inside the
track rails.
3. All necessary mounting fasteners.
NOTE: The track may be installed to permit the table to
slide out through either the right side or left side door.
The right side is shown in the illustrations.
3.3.2 Combine the table assembly and track by sliding
the table assembly rollers into the track channels, as
shown in Figure 5.
NOTE: If the weight of the table and track make it too
heavy to install as an assembly, the track may be placed
in the cabinet to predrill mounting holes, but the table
must also be in place within the rails before fasteners
are installed.

3.3.4 Match drill two 1/2" diameter holes on each side
of the cabinet, using the holes in the mounting brackets
as a template. NOTE: To prevent the track from shifting,
temporarily place a 3/8-NC x 1-1/2" bolt through each
hole after it is drilled.
3.3.5 After the holes are drilled and the table
assembly is placed in the track rails, secure all
fasteners.
3.4 Manometer
3.4.1 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
outlet damper; refer to Section 5.4 to adjust static
pressure. Refer to Section 5.8 for manometer instructions.
The optional manometer kit is listed in Section 9.1.
3.5 Differential Pressure (Magnehelic) Gauge
3.5.1 The differential pressure gauge measures
pressure drop across the filter cartridge. The gauge is
the best way to monitor cleaning efficiency and dust
buildup on the cartridge.
3.5.2 The gauge panel, gauge, filter, and panel fittings
come fully assembled; the bushings, snubber fittings,
and tubing are loose. Mount the panel on the cabinet or
power module at a location where it can be easily
monitored. There is not enough room on a Pulsar 55se
to mount it at the front of the cabinet, choose another
convenient location. Note: A 20-foot length of tubing is
included with the kit, allowing the panel to be mounted
within ten feet of the dust collector connections, as
shown in Figure 7.
3.5.3 Mounting holes are on left side and at the bottom
of the gauge panel. After selecting the location, match drill
holes, and use nuts and cap screws to secure the panel.
Note: make sure the panel is close enough to the dust
collector for ten feet of tubing to reach.
3.5.4 Remove 1/4" pipe plugs from the dust collector
body, and install 1/4" x 1/8" bushings and snubber
fittings as shown in Figure 7.
3.5.5 Connect the 1/4" tubing to the snubber fittings
and gauge as shown, by removing the fitting’s
compression nut; slide it over the end of the tubing, insert
the tubing into the fitting, and tighten the nut onto the
fitting.
3.5.6 Refer to the Magnehelic differential pressure
gauge manual provided for operation of the gauge.

4.0 OPERATION
4.1 Season Filter Cartridge
NOTICE
Do not pulse a new dust collector or
replacement filter cartridge until the cartridge is
seasoned per Section 7.8. Pulsing unseasoned
cartridges decreases the efficiency of collector
and life of the cartridge.
4.2 Media Loading and Unloading
4.2.1 Media Loading: With the exhauster OFF, add
clean dry media by pouring it into the reclaimer hopper
through the reclaimer door. Do not fill above the cone on
the reclaimer. Do not pour media directly into the
cabinet hopper, as overfilling may occur. Overfilling
will result in media carryover to the dust collector and
possible blockage in the conveying hose. Refill only after
all media has been recovered from the cabinet.
The minimum amount of media to charge the system is
10 Lbs.
4.2.2 Media Unloading: To empty the cabinet and
reclaimer of media, blow-off the cabinet interior and run
the exhauster until all media is recovered from the
cabinet. Turn OFF the exhauster, and place an empty
container under the metering valve. Unscrew the plastic
plug from the metering valve, permitting media to flow
into the container. If media doesn't flow, it has caked.
Open the fill door and stir media until it starts to flow.
Replace the plug when the reclaimer is empty.
4.3 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.
4.3.1 Parts must be free of oil, water, grease, or other
contaminants that will cause media to clump or clog
filters.
4.3.2 Load and unload parts through either door.
4.3.3 Close door; the door interlock system will
prevent blasting if either door is open.
4.4 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
blower running 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 After the filter cartridge is seasoned per Section
7.8, adjust the pulse pressure regulator to 60 psi. Refer
to Section 5.6 for adjustment procedure.
4.4.3 Turn ON lights and exhauster. The on/off toggle
switch performs both functions.
4.4.4 Load parts.
4.4.5 Close door; the door interlock system will
prevent blasting if either door is open.
4.4.6 Adjust the pilot pressure regulator to the
required blast pressure per Section 5.1. The regulator is
located on the top, left side of the cabinet.
4.4.7 Insert hands into rubber gloves.
4.4.8 To blast, hold the gun firmly and apply pressure
to the foot pedal; blasting will begin almost immediately.
NOTE: When holding 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.
4.4.9 When blasting small parts, place an
appropriately-sized screen over the grate to prevent parts

PULSAR®55se ERGONOMIC SUCTION BLAST CABINET Page 8
© 2015 CLEMCO INDUSTRIES CORP. www.clemcoindustries.com Manual No. 25727 Rev. C
from falling into the hopper. If an object should fall through
the grate, stop blasting immediately and retrieve it.
WARNING
Shut down the cabinet immediately if dust
discharges from the dust collector or cabinet.
Check to make sure the dust collector filter
cartridge is correctly seated and that it is not
worn or otherwise damaged. Prolonged
breathing of any dust could result in serious
lung disease. Short term ingestion of toxic dust
such as lead, poses an immediate danger to
health. Toxicity and health risk vary with type of
media and dust generated by blasting. Identify
all material being removed by blasting, and
obtain a safety data sheet (SDS) for the blast
media.
4.5 Stop Blasting
4.5.1 To stop blasting, remove pressure from the foot
pedal.
4.5.2 Use the blow-off nozzle to blow media off
cleaned parts. Allow the exhauster to clear the cabinet of
airborne dust before opening the door.
4.5.3 Unload parts. Shut off the air supply valve, drain
the air filter and pulse reservoir, and switch OFF the
lights and exhauster.
4.6 Blasting Technique
4.6.1 Blasting technique is similar to spray painting
technique. Smooth continuous strokes are usually most
effective. The distance from the part affects size of blast
pattern. Under normal conditions hold the gun
approximately 3" to 6" from the surface of the part.
4.7 Pulsing (Cleaning) Dust Collector Cartridge
4.7.1 The dust collector filter cartridge is pulsed each
time the foot pedal is pressed or released. Prolonged
periods of blasting or dusty conditions may require the
cartridge to be pulsed during the blasting process per
Section 6.4.
5.0 ADJUSTMENTS
5.1 Blasting Pressure, refer to Figure 8
5.1.1 The pilot regulator, located on the top, left side of
the cabinet, enables the user to adjust blasting pressure
to suit the application. The suitable pressure for most
purposes is 80 psi. Lower pressures may be required on
delicate substrates, and will reduce media breakdown.
Higher pressure may be required for difficult blasting jobs
on durable substrates, but will increase media break
down. If pressure is too high, suction in media hose will
decrease, and if high enough cause blow-back in the
hose. In all cases, optimal production can only be
achieved when pressure is carefully monitored.
5.1.2 To adjust pressure, pull the knob to unlock it,
then turn it clockwise to increase pressure or counter-
clockwise to decrease pressure. Pressure may drop
from closed-line pressure when blasting is started. Once
operating pressure is set, push the knob in to lock it and
maintain the setting.
Figure 8
5.2 Air Jet Adjustment, Figure 9
5.2.1 The air jet should be screwed 4-1/2 to 5 full
turns into the gun body. Doing so will leave 3-1/2 to 4
threads exposed past the lock nut. Tighten the lock nut
to hold the jet in place. Refer to Section 9.3 for optional
adjusting tool, which correctly positions the jet.

5.3 Media/Air Mixture, Figure 10
5.3.1 Check the media stream for correct media/air
mixture; media flow should be smooth and appear as a
light mist coming from the nozzle.
Figure 10
5.3.2 If media does not flow smoothly, loosen the lock
nut, and adjust the metering screw until the upper holes in
the metering stem are closed-off, and the lower holes are
fully open, as shown in Figure 10. This adjustment is a
starting point.
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 lock nut
and slowly turn the adjusting screw out
(counterclockwise when viewed from the top) until media
flows smoothly. Tighten the lock nut 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 lock nut to
maintain the setting.
5.4 Static pressure
5.4.1 Static pressure requirements vary with size of
reclaimer and size, weight, and type of media.
5.4.2 Adjust static pressure by opening or closing the
outlet damper located above the reclaimer on the
underside of the power module top, refer to Figure 11. If
the damper is not opened far enough, the reclaimer will
not remove fines, resulting in dusty media, poor visibility,
or will not convey media, causing media build-up in the
hose between the cabinet hopper and reclaimer. 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 damper only as
far as necessary to obtain a balance of maximum dust
removal without media carryover.
Figure 11
5.4.3 A manometer is useful when adjusting and
monitoring static pressure. The manometer kit is listed
under Optional Accessories in Section 9.1. Refer to
Section 5.8 for 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. 8 to 12 .............................3"-to to 3-1/2"
Alox. 60 to 80 ........................................................4" to 5"
Alox. 80 to 180 ......................................................3" to 4"
5.4.4 As dust accumulates on the outer surface of the
cartridge, static pressure drops, requiring additional
pulsing of the cartridge or an increase in pulse pressure
as described in the auto-pulse supplement sheet. When
pulsing no longer maintains the necessary static
pressure, readjust the damper.

5.5 Door Interlocks, Figure 12
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 the doors are 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 usually 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 adjusting bracket
up or down, and the adjusting screw sideways, to center
the adjusting 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.
Figure 12
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 only open the door enough to disengage
the interlock switch. The interlocks should prevent
blasting when either door is open, 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 ON.
5.6 Pulse Pressure
NOTICE
Do not pulse new dust collectors or
replacement cartridges until the cartridge is
properly seasoned. Refer to Section 7.8.
Pulsing unseasoned cartridges could cause
premature cartridge failure or decrease the
efficiency of dust collector.
5.6.1 Adjust pulse pressure using the regulator
mounted on the pulse reservoir, as shown in Figure 13.
Begin pulse at 60 psi. To adjust pressure, pull the knob
to unlock it, as shown in Figure 13, turn clockwise to
increase pressure or counterclockwise to decrease
pressure. Once operating pressure is set, push the knob
to lock it and maintain the setting.
Viewed from back of power module
Figure 13
5.6.2 As the filter cartridge cakes with dust, it may be
necessary to pulse between blasting, per Section 6.4.
5.6.3 When pulsing alone does not adequately clean
the cartridge, increase pulse pressure in 5-psi
increments until the maximum of 90 psi is reached. As
dust cakes on the cartridge, the differential pressure
increases. Using a gauge to measure the differential
pressure is a good way to tell if the cartridge is heavily
caked.

6.4 does not increase visibility or decrease differential
pressure, replace the cartridge per Section 7.7.
5.7 Inlet Damper
5.7.1 Once the inlet is initially set per Section 2.5, 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 outlet damper. See Section 5.4.
Reclaimer pressure must be set before cabinet
pressure. In rare circumstances, cabinet pressure may
need to be slightly higher or lower.
5.7.2 A manometer (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 further to decrease static pressure or
close it further to increase pressure.
5.7.3 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.
5.8 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.
5.8.1 Refer to directions packed with the manometer
for preparation and operating instructions for the
manometer.
5.8.2 Connect one end of the 3/16" ID tubing to one of
the tubing connectors (elbow) at the top of the
manometer by pushing it over the barbed adaptor.
5.8.3 Open both manometer valves (elbows) per the
instructions with the manometer.
5.8.4 Magnets on the manometer hold it in position on
the reclaimer body or dust collector body. The
manometer must be vertically-plumb so the fluid is level
on both sides.
5.8.5 Adjust the slide rule to align the zero with the
fluid level. Refer to Figure 15.
5.8.6 Needle placement: Ref. Figure 14.
5.8.6.1 To take frequent readings: Permanently install
the manometer for taking frequent readings. Remove the
1/4" NPT plug from the coupling on reclaimer body and
install a fitting with a 1/8" hose barb. Use thread sealer
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.
Figure 14
5.8.6.2 To take occasional readings: Leave the
needle protector on the needle and insert the needle into
the unused end of the tubing. The ends of the tubing
must fit tight on the manometer and needle; leaks will
give inaccurate readings. 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 door gasket, creating an airtight seal
When taking occasional
readings, position the
needle so the point is
inside the door opening.
Carefully close the door
on the needle.
For taking frequent readings,
remove 1/4-NPT plug and
install a permanent fitting in
the coupling, as shown.
Reclaimers are for reference and
may differ from those shown.

5.8.7 Open cabinet doors and 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.
5.8.8 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
5.8.9 After taking the readings, replace the needle
protector. Close the manometer valves and store the
manometer in the original container in a clean area.
Note: If the manometer installation is permanent, the
manometer may remain on the reclaimer body after the
valves are closed.
5.9 Foot Shelf
5.9.1 Raise the shelf to remove pressure from the
locating pins and remove the pins. Adjust the shelf
height and insert the pins.
6.0 PREVENTIVE MAINTENANCE
WARNING
Failure to wear approved respirators and eye
protection when servicing dust-laden areas of
the cabinet and dust collector and when
emptying the dust container could result in
serious eye irritation and lung disease or death.
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.
Note: To avoid unscheduled downtime, establish a
weekly inspection schedule. Inspect all parts subjected
to media contact, including: the gun, nozzle, media
hose, flex hose, wear plate, and all items covered in this
section.
6.1. BNP Gun Assembly
6.1.1 Inspect internal parts of the BNP gun for wear.
Inspection and replacement of the air jet cover before it
wears through will prolong the life of the jet.
6.2. Dust Collector Dust Container
6.2.1 Empty the dust container regularly. Start by
checking the container at least daily or when adding
media, then adjust frequency based on usage,
contamination and friability of the media.
6.2.2 Turn OFF the exhauster and release the dust
container from the lid. The lid's flexible inlet hose allows
easy removal. Remove the liner and dump the contents
or the tied-off liner into a suitable disposal receptacle.
Replace the liner and attach the container to the lid
The manometer must be vertical when
taking pressure readings.
With the exhauster OFF,
slide the rule to align the
zero with the fluid level.
To obtain the pressure reading: With the
exhauster ON, add the number of
inches the fluid travels up the column, to
the inches the fluid travels down the
other column. The total is the static
pressure reading.
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.

making sure the lid and clamp are secure. Replacement
liners are shown in Section 9.9, Figure 33, Item 21.
NOTE: Blasting media is usually non-toxic, however,
materials being removed by the blast process may be
toxic. Obtain SDS sheets for the media and identify all
material removed by the blast process. Check with
proper authorities for disposal restrictions.
6.3 Pulse reservoir, Figure 16
6.3.1 Open the petcock to drain water from the pulse
reservoir before and after each use.
Figure 16
6.4 Cartridge Pulsing
6.4.1 The cartridge is pulsed each time the foot pedal
is pressed or released. Additional pulsing should be
performed per the following instructions every eight
hours, or more often under dusty conditions, to prevent
clogging of the cartridge.
6.4.2 Turn OFF exhauster.
6.4.3 Hold the blast gun and rapidly press and release
the foot pedal three times. Activating the foot pedal more
than three times may cause dust to escape from the
enclosure.
6.4.4 Start the exhauster and let it run for 10 seconds
or until all airborne dust is cleared from the cabinet.
6.4.5 Repeat the process several times.
6.5 Reclaimer Debris Screen
6.5.1 The screen is accessible through the reclaimer
door. With the exhauster OFF, remove the screen and
empty it daily or when loading abrasive. Empty the
screen more often if the parts blasted causes excessive
debris. Always replace the screen after cleaning.
6.6 View Window Cover Lens
6.6.1 Rapid frosting of the view window can be
avoided by directing ricocheting media away from the
window, and by installing a protective cover lens on the
inside surface of the window. Using cover lenses
prolongs the life of the view window.
6.6.2 The easiest 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.
6.6.3 To install a cover lens, carefully remove the
adhesive backing, leaving the adhesive on the lens, and
apply the lens to the clean, dry, inner surface of the view
window. Replace the cover lens when it becomes pitted
or frosted.
6.7 Compressed-Air Filter
6.7.1 The cabinet is equipped with a manual-drain air
filter. Drain the filter at least once a day, or more often if
water is present. Moist air inhibits the flow of media.
Drain the air line and receiver tank regularly. If the filter
does not remove enough moisture to keep media dry
and flowing, it may be necessary to install an air dryer or
aftercooler in the compressed-air supply line.
6.8 Media Hose
6.8.1 To avoid unscheduled down-time, periodically
inspect the media hose for thin spots, by pinching it
every 6 to 12 inches.

per Section 5.3.
8.5 Media bridging
8.5.1 Frequent bridging or blockage in the media
metering valve can be caused by damp media. Media
becomes damp by blasting parts that are slightly oily, from
moist compressed-air, or from absorption from ambient air.
8.5.2 To avoid contaminating media from the work-
piece, all parts put into the cabinet should be clean and
dry. If parts are oily or greasy, degrease and dry them
prior to blasting.
8.5.3 Moist compressed air may be due to a faulty
compressor that overheats, or pumps oil or moisture into
the air line, too long an air line permitting moisture to
condense on the inside, and from high humidity. Drain
the air filter and receiver tank regularly. Ongoing
problems with moist air may require the installation of an
air dryer or aftercooler in the air supply line.
8.5.4 Absorption. Some media tends to absorb
moisture from the air, especially fine-mesh media in
areas of high humidity. Empty the media and store it in
an airtight container when cabinet is not in use.
8.5.5 A vibrator attached to the reclaimer cone or
metering valve may help to prevent bridging of fine-
mesh media.
8.6 Media surge
8.6.1 Heavy media flow. Adjust media/air mixture per
Section 5.3.
8.7 Blockage in media hose
8.7.1 Media obstructions. Usually caused when the
media mixture is too rich. Adjust media/air mixture per
Section 5.3.
8.7.2 Wet or damp media. Refer to Section 8.5.
8.8 Poor suction in media hose
8.8.1 Inadequate air supply. Check the tables in
Figures 2 and 3.
8.8.2 Air jet needs adjustment. Check adjustment per
Section 5.2.
8.8.3 Nozzle worn. Replace if worn 1/16" or more.
8.8.4 Blockage in media hose or nozzle. Refer to
Sections 8.4 and 8.7.
8.8.5 Wrong size-combination of air jet and nozzle
Refer to the table in Figure 2.
8.8.6 Air jet sleeve extends past end of air jet. Cut the
sleeve even with the air jet.
8.8.7 Nozzle pressure too high, refer to Section 5.1.
8.8.8 Nozzle inserted backward; the tapered end of
the nozzle should face toward the air jet.
8.9 Air only (no abrasive) from nozzle
8.9.1 Make sure the reclaimer contains media.
8.9.2 Check media hose for blockage. Media
obstructions is usually caused when the media mixture
is too rich, adjust media/air mixture per Section 5.3.

8.9.3 Make sure the air hose and media hose are not
reversed; the air hose attaches to the back of the gun
and the clear media hose attaches to the bottom of the
gun’s grip. Refer to Figure 28.
8.10 Blow-back through media hose
8.10.1 Blockage in nozzle. Remove the nozzle and
check for blockage.
8.10.2 Air jet may be too large for nozzle. Refer to the
table in Figure 2.
8.11 Blasting does not begin when the foot pedal
is pressed.
8.11.1 Door interlocks not engaging. Check adjustment
per Section 5.5.
8.11.2 Blocked or leaking control lines. Check all
urethane tubing for blockage or leaks.
8.11.3 Foot pedal valve malfunction. Check foot pedal
alignment, and inlet and outlet lines for pressure.
8.11.4 Pressure regulator may be set too low or OFF.
Check pressure on pilot regulator.
8.11.5 Make sure that the air compressor is operating
and air supply valves are open.
8.11.6 Check the nozzle to see if it is plugged. Refer to
Section 8.4.
8.11.7 Make sure lines are not reversed on the foot pedal
or pilot regulator. Refer to the schematic in Figure 28.
8.12 Blasting continues when foot pedal is released
8.12.1 Make sure the 3-way valve in the foot pedal
exhausts air when the pedal is released. If it does not
exhaust, check the inbound air line for blockage, if no
blockage, replace the valve.
8.13 Static shocks
8.13.1 Cabinet and/or operator not grounded. Abrasive
blasting generates static electricity. The cabinet must be
grounded to prevent static buildup. Refer to Section 2.3.
If shocks persist, the operator may be building up static.
Attach a small ground wire, such as a wrist strap, from
the operator to the cabinet.
8.13.2 Gloves wearing thin. Inspect gloves and replace
them as needed.
8.13.3 Avoid holding parts off the grate. Static will build-
up in the part if not dissipated through the metal cabinet.
8.14 Dust leaking from dust collector
8.14.1 Cartridge not seasoned, season cartridge per
Section 7.8.
8.14.2 Damaged or loose cartridge. Inspect filter
cartridge, tighten or replace as needed.
8.14.3 Faulty seal on the dust collector hopper gasket.
Inspect gasket and replace if damaged.
8.15 Dust collector does not pulse when foot
pedal is pressed or released.
8.15.1 Check pressure on dust-collector pulse-
pressure gauge. If low, adjust pulse pressure per
Section 5.6.
8.15.2 Refer to Figure 22 and make sure the 3-way
pulse valve has not come loose from the mounting
bracket. Tighten the retaining nut as needed to secure.
8.15.3 If the cam follower tilts to one side, one or both
roll pins are bent or missing. Remove the two screws on
the bottom of the pedal and remove the switch and cam
follower assembly. Center the cam follower and replace
roll pins as needed to hold the cam follower in place.
Refer to Figure 21.
8.15.4 Check alignment of pulse-valve cam follower:
With the exhauster running and with blast pressure
adjusted to 0 psi, hold the foot pedal in hand and fully
press the pedal top. The collector should pulse as the
cam follower rides over the lobe on the pedal top when
the pedal is pressed, and again when the pedal is
released, as shown in Figure 22. Note: The pedal should
be rapidly pressed and released so the cam follower
quickly rides over the lobe; prolonged engagement of
the pulse valve will lengthen the pulse, which does not
clean the cartridge and wastes compressed air.
The lobe on the pedal top should press the cam follower
IN to engage the 3-way pulse valve, and disengage the
switch when the pedal is fully pressed and again when
the pedal is released. If the switch is not aligned to
function as described, align as follows:
If the switch does not disengage the pulse when the
cam follower rides off the lobe, the switch assembly
is too close to the lobe. Loosen the two screws on
the bottom of the pedal and slide the switch away
from the lobe as needed and recheck alignment.
