1.4 General Description
1.4.1 Refer to Figure 1 for arrangement of
components. The Pulsar cabinet encloses the blasting
environment to provide efficient blasting while
maintaining a clean surrounding work area. Production
rates are influenced by size of air jet and nozzle,
compressor output, working pressure, type and size of
media, and angle and distance of the nozzle from the
blast surface. Pulsar 55se cabinets consist of two major
components.
1. Cabinet Enclosure
2. Power Module
1.4.2 Cabinet enclosure
Approximate work chamber dimensions:
42" wide x 23" deep x 30" high.
1.4.3 Power module:
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
1.5 Theory of Operation
1.5.1 Once the cabinet is correctly set up and turned on,
the cabinet is then ready for operation by actuation of the
foot pedal. Fully depressing down on the foot pedal causes
air to flow through the blast gun. The partial vacuum
created by air moving through the gun draws media into
the blast-gun mixing chamber. The media mixes with the
air stream and is propelled out the nozzle. After striking the
object being blasted, the blast media, fines, dust, and
byproducts generated by blasting fall through the grate into
the cabinet hoppers. 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 filter, discharging clean
air. When the foot pedal is released, blasting stops.

Some items rotated for clarity.
Figure 1
1.5.2 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. An optional automatic pulse kit can
be added to pulse the cartridge at timed intervals during
blasting. See Section 9.1: Optional Accessories.
1.6 Nozzle Options
1.6.1 Unless otherwise specified at the time of
purchase, the cabinet is provided with a No. 5 (5/16"
orifice) ceramic nozzle and No. 5 (5/32" orifice) air jet.
Optional, more durable tungsten carbide and boron
carbide nozzle are available and are shown in Section
9.6: BNP Gun and Feed Assembly. Use boron carbide
nozzles when blasting with aggressive media, as noted
in Section 1.8.4.

1.7 HEPA (high-efficiency particulate air) Filter
1.7.1 Optional HEPA afterfilter provides additional
filtration. A HEPA filter must be used when removing
toxic coatings, heavy metals, or any other toxic
materials. HEPA filter is listed in Section 9.1: Optional
Accessories.
WARNING
All dust is hazardous to breath. 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 breath.
1.8 Blasting Media
1.8.1 Always use media specifically manufactured for
blasting and that are compatible with the surface being
blasted. Media produced for other applications may be
inconsistent in size and shape, contain particles that
could plug the nozzle or media metering valve, or cause
irregular wear. Always obtain the safety data sheet
(SDS) for the blasting media prior to blasting and identify
material being removed by blasting, paying particular
attention to worker health risks and presence of any
hazardous/toxic substances.
Most common reusable media specifically manufactured
for blasting can be used in Pulsar® 55se cabinet. The
listing of media sizes shown in this section are provided
as a guideline only. The guideline is based on standard
5/32" orifice air jet with 5/16" nozzle and average
conditions, with variables such as blast pressure, media-
air mixture, visibility inside the cabinet, humidity, and
reclaimer cleaning rate.
Several variables that affect 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 dust filters).
As a rule, larger orifice air jets and nozzles deliver more
media, requiring higher performance from the reclaimer.
When using larger nozzles, the maximum mesh size of
media will be smaller than normally recommended.
Using media finer than those recommended may
decrease visibility and, at some point, carry over 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 shot and steel grit Steel grit or shot
should not be used with the Pulsar® 55se cabinet. Steel
is too heavy to use with cabinets equipped with 300 cfm
reclaimers.
1.8.3 Sand and slag: Sand and slag media are not
suitable for cabinet use. Sand should NEVER be used
for abrasive blasting because of the respiratory hazards
associated with media containing free silica. Slags are
not recommended for cabinet use because they rapidly
break down and are not recyclable.
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 downtime and maximize cabinet
life, periodically inspect the reclaimer wear plate, blast
hose, and nozzle for wear and replace parts as needed.
When using aggressive media, install an optional
aluminum oxide kit, which includes rubber curtains for the
cabinet interior and a boron carbide-lined nozzle.
Nozzles lined with boron carbide extend nozzle wear life.
Refer to Section 9.2: BNP Gun and Feed Assembly.
1.8.5 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 in
environments of moderately high humidity. Glass beads
subjected to excessive moisture may be reused only
after thoroughly drying and breaking up any clumps.
1.8.6 Plastic media: Plastic and similar lightweight
and/or nonaggressive 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.
1.8.7 Bicarbonate of soda: Bicarbonate of soda is
not recommended for use in standard cabinets. Bicarb is
a one-use media, which will quickly saturate the filter
cartridge(s). Best performance from bicarb media is
achieved with pressure blasting, requiring a pressure
vessel. Refer to Clemco’s Aerolyte cabinet line for
cabinets that are specifically designed for use with
bicarbonate of soda.

1.9 Compressed-Air Requirements
1.9.1 The size of the compressor required to operate
the cabinet depends on the size of the air jet and
blasting pressure. Unless otherwise specified, cabinets
are supplied with a No. 5 (5/32" orifice) jet. Refer to the
table in Figure 2 to determine air consumption. Consult
with a compressor supplier for a suggested compressor
size based on the air consumption.
Compressed-Air Consumption in CFM
BNP Gun
Jet
Orifice
Nozzle
Orifice CFM PSI
No. 4 1/8" 5/16" 21 80
No. 5 5/32" 5/16" 33 80
*No. 6 3/16" 3/8" 48 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
1.9.2 The air filter at the air-inlet connection, removes
condensed water from the compressed air. Its use is
especially important in areas of high humidity or when
using fine-mesh media. Moisture causes media to clump
and inhibits free flow through the feed assembly. If the
filter does not remove enough moisture to keep media
dry and flowing, it may be necessary to install an air
dryer or aftercooler in the air-supply line.
1.10 Electrical Requirements
1.10.1 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. FLA 20/7, 208/3.4, 240/3.5.
1.10.2 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 large parts.
2.2 Connect Compressed-Air Supply Line
WARNING
Failure to observe the following before
connecting the equipment to the compressed-
air source can cause serious injury from the
sudden release of trapped 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 a lockout
and tagout procedure and depressurization of
the compressed-air line before performing
maintenance.
2.2.1 Refer to Paragraph 2.2.2 to determine the
recommended air-supply hose size, 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 1/2-NPT air filter located within the
power module. The style of connection shown in Figure
4 is for reference only.
2.2.2 Refer to the table in Figure 3 to determine the
minimum ID of air-supply line to the cabinet. A smaller
diameter hose may reduce blasting efficiency.

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 within
the power module.
WARNING
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.
2.3 Ground the Cabinet
2.3.1 To prevent static electricity buildup, 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 Standard Pulsar-55se cabinets are 120-volt single
phase. Power is supplied by a U-ground plug; plug it into
a 120-volt outlet. No additional wiring is needed; the
wiring schematic shown in Figure 5 is for reference.
WARNING
Do not use electrical adaptors that eliminate the
ground prong on 120-volt plugs. Doing so can
cause electric shock and equipment damage.

damper shows the settings in degrees. For the initial
setting, align the handle 30 degrees.
Figure 6
2.5.2 Loosen the lock nuts and position the damper
handle as noted. When correctly positioned, tighten the
lock nuts to maintain the setting. Refer to Section 5.7 for
adjustment procedure.
2.6 Final Assembly
2.6.1 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.
2.6.2 A package of five 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. Refer to Section 7.3. When
the cover lens becomes pitted or frosted, replace it.
3.0 FIELD INSTALLED ACCESSORIES
3.1 Aluminum Oxide (aggressive media) Kit
3.1.1 An optional aluminum oxide kit is available
factory installed or may be field installed later.
Factory-installed kits consist of black-rubber cabinet
curtains with grommets, curtain hardware, and a boron
carbide nozzle.
Field-installed (or replacement factory installed) kits
consist of black-rubber cabinet curtains (refer to Section
3.2 for curtain installation) a boron carbide nozzle, and
light-lined flex hose. If the existing flex hose is in good
condition, reserve the new hose for future replacement.
3.2 Cabinet Curtains 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 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 drill and thread the screws through the door’s inner
wall at each grommet.

illustrations.
3.3.2 Combine the table assembly and track by sliding
the table assembly rollers into the track channels, as
shown in Figure 7.
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.
3.3.3 Refer to Figure 8 and center the track and table
assembly inside the cabinet on top of the grate. Make
sure the two angled mounting brackets are facing toward
the door from which the table will slide.
Figure 8
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.
Figure 9
3.4 Manometer
The optional manometer kit is listed in Section 9.1.
3.4.1 The manometer measures static pressure.
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. 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.
3.5 Reclaimer Differential Pressure Gauge
Monitors reclaimer static pressure ‒ Figure 10
3.5.1 The reclaimer differential pressure gauge
continually measures reclaimer static pressure, similar to
a manometer slack tube but it uses a differential
pressure gauge.
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 at a location
where it can be easily monitored. A 10-foot length of
tubing is included with the kit, allowing the panel to be
mounted within ten feet of the connections. One
suggestion is to mount it on an accessible side of the
power module.
3.5.3 Mounting holes are on the left and right sides of
the gauge panel. After selecting the location, match drill
holes, and use nuts and cap screws to secure the panel.
3.5.4 Remove the 1/4" pipe plug from the reclaimer
body and install 1/4" x 1/8" bushing and barb fitting, as
shown in Figure 10.
Figure 10

3.6 Dust-Collector Differential Pressure Gauge
3.6.1 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.
3.6.2 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. A 20-foot length of tubing is
included with the kit, allowing the panel to be mounted
within 10 feet of the dust collector connections, as
shown in Figure 11.
3.6.3 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 10 feet of tubing to reach.
3.6.4 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 11.
3.6.5 Connect the 1/4" tubing to the snubber fittings
and gauge, as shown by removing the fitting’s
compression nut, sliding it over the end of the tubing,
inserting the tubing into the fitting, and tightening the nut
onto the fitting.
3.6.6 Refer to the differential pressure gauge manual
provided for operation of the gauge.
3.7 Armrest ‒ Figure 12
3.7.1 Position the assembly so the armrest is about
even with the bottom of the arm port opening. Mark one
hole location on the front of the cabinet at each
mounting bracket.
3.7.2 Drill a 3/8" hole at both locations and mount the
armrest using 5/16 bolts, washers and nuts. Install the
bolts from inside the cabinet to protect the threads from
abrasion, should the armrest need to be removed later.
3.7.3 Match drill the remaining four bracket holes and
install the remaining fasteners.
3.7.4 Loosen the fasteners on the slotted bracket and
raise or lower the armrest to a comfortable position.

4.0 OPERATION
4.1 Season Filter Cartridge
NOTICE
Do not pulse a new dust collector or
replacement filter cartridge until the cartridge is
properly seasoned, per Section 7.10.
Pulsing unseasoned cartridges can decrease
the efficiency of dust collector and cause
premature cartridge failure.
4.2 Media Loading
4.2.1 Media capacity: The approximate capacity and
minimum media amount is shown in the table in below.
Reclaimer Size Minimum Wt. Capacity
300 cfm 10 lbs 50 lbs (0.5 cuft)
4.2.2 Media loading: With the exhauster OFF, add
clean, dry media by pouring it through the reclaimer
door. Do not fill above the hopper on the reclaimer. Do
not pour media directly into the cabinet hopper, as
overfilling may occur. Overfilling will result in media
carry over to the dust collector and possible blockage in
the conveying hose. Refill only after all media has been
recovered from the cabinet.
4.3 Media Unloading ‒ Figure 13
4.3.1 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 bucket or other suitable
container under the metering valve. Unscrew the plastic
plug from the metering valve, permitting media to flow
into the bucket. If media does not flow, it has caked;
open the fill door and stir media until it starts to flow.
Before the container becomes too heavy to easily
manage, replace the plug and empty the container.
Replace the plug when the reclaimer is empty, or, if
changing media type, purge the media hose, as noted
below.
4.3.2 To purge the media hose, before replacing the
plug turn ON the exhauster, grasp the gun, and press
the foot pedal using the gun to blow off the cabinet
interior until the air from the gun and the cabinet are
clear. Turn OFF the exhauster and replace the plug.
Figure 13
4.4 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.
NOTE: Parts must be free of oil, water, grease, or
other contaminants that will clump media or clog
filter cartridge.
4.4.1 Load and unload parts through either door.
4.4.2 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.

4.4.3 Close door; the door interlock system will
prevent blasting if either door is open.
4.5 Blasting Operation
W
ARNING
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 doors.
 After blasting, keep doors 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.
4.5.1 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.
4.5.2 After the filter cartridge is seasoned, per Section
7.10, adjust the pulse pressure regulator to 60 psi. Refer
to Section 5.6 for adjustment procedure.
4.5.3 Turn ON lights and exhauster. The ON/OFF
toggle switch performs both functions.
4.5.4 Load parts.
4.5.5 Close door; the door interlock system will
prevent blasting if either door is open.
4.5.6 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.
4.5.7 Insert hands into rubber gloves.
4.5.8 To blast, hold the gun firmly, point the gun
toward the object to be blasted, and apply pressure to
the top of the foot pedal; blasting will begin almost
immediately.
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 can result in serious lung
disease. Short-term ingestion of toxic dust,
such as lead or heavy metals, 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.
4.5.9 When blasting small parts, place an appropriately
sized screen over the grate to prevent parts from falling
into the hopper. If an object should fall through the grate,
stop blasting immediately and retrieve it.
NOTICE
To prevent rapid frosting of the view window,
install a view-window cover lens, per Section
7.3, and avoid pointing the blast nozzle toward
the view window
4.5.10 When blasting parts off the grate, use a solid
conductive back rest to support the part. Without this
assist, especially with longer blasting operations, the
operator will tire easily from resisting blast pressure, and
static electricity could build up in the ungrounded part
and cause static shocks. Whenever possible, avoid
holding small parts that require blasting into the glove.
4.6 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 Stop Blasting
4.7.1 To stop blasting, remove foot pressure from the
top of the foot pedal.
4.7.2 Use the blow-off nozzle to blow media off
cleaned parts.

PULSAR® 55se ERGONOMIC SUCTION BLAST CABINET Page 12

4.7.3 Keep doors closed and exhauster running until
the cabinet is clear of all airborne dust.
4.7.4 Unload parts.
4.8 Pulsing (cleaning) Dust Collector Cartridge
4.8.1 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 6.2.4, or upgrade to an automatic pulse kit. See
Section 9.1.
4.9 Shutdown
4.9.1 Shut off the air-supply valve, bleed the air-
supply line, and drain the compressed-air filter and dust-
collector pulse reservoir.
4.9.2 Switch OFF the lights and exhauster.
5.0 ADJUSTMENTS
5.1 Blasting Pressure (pilot regulator) – Figure 14
5.1.1 The pilot regulator (located on the top-left side of
the cabinet), enables the user to adjust blasting pressure
while blasting, 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 it could increase media break down. If pressure is too
high, suction in media hose will decrease, and if high
enough can cause blow-back in the media hose. Optimal
production can only be achieved when pressure is
carefully monitored.
Figure 14
5.1.2 To adjust pressure, unlock the knob by pulling it
out, as shown in Figure 14, and turn it clockwise to
increase pressure or counterclockwise to decrease
pressure. Pressure may drop slightly from closed-line
pressure when blasting starts. Once operating pressure
is set, push the knob to lock it and maintain the setting.
5.2 Air Jet Adjustment ‒ Figure 15
5.2.1 Thread the air jet 4-1/2 to 5 full turns into the gun
body. Doing so leaves 3-1/2 to 4 threads exposed past the
lock nut. Tighten the lock nut to maintain the setting. Refer
to Section 9.2 for optional adjusting tool, which correctly
positions the jet. Instructions are provided with the tool.
Figure 15
5.3 Media-Air Mixture, Figure 16
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 16
5.3.2 If media does not flow smoothly, loosen the
locking nut, and adjust the metering screw until the
upper holes in the metering stem are closed off and the
lower holes are fully open, as shown in Figure 16. 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 the
media flows smoothly. Tighten the lock 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 lock nut
finger-tight to maintain the setting.
5.4 Reclaimer Static Pressure
5.4.1 Correct static pressure varies with the 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 underside of the power module top; as
shown in Figure 17. If the damper is not opened far
enough, the reclaimer will not remove fines, resulting in
dusty media and poor visibility, or will not convey media,
causing media buildup in the hose between the cabinet
hopper and reclaimer. If the damper is opened too far, it
may cause carry over (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 media carry
over.
Figure 17
5.4.3 A manometer is useful for adjusting and
monitoring static pressure. The manometer kit is listed in
Section 9.1: Optional Accessories. Refer to Section 5.8
for manometer operations. 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 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 carry over is attained.

Aluminum Oxide 60-Mesh to 80-Mesh .................. 4" – 5"
Aluminum Oxide 80-Mesh to 180-Mesh ................ 3" – 4"
5.4.4 As dust accumulates on the outer surface of the
cartridge, static pressure drops, requiring additional
pulsing of the cartridge as described in Section 6.2.4, or
an increase in pulse pressure, per Section 5.6. When
pulsing no longer maintains the necessary static
pressure, readjust the damper.
5.5 Door Interlocks ‒ Figure 18
WARNING
Never bypass the door interlock system. Doing
so can result in serious injury from unexpected
blasting.
5.5.1 The door interlocks disable the blasting control
circuit when doors are open. To enable blasting, the
door-interlock switches must be engaged when doors
are closed. The interlocks are set at the factory and do
not normally require field adjustment unless parts are
replaced. If adjustment is required, proceed as follows.
5.5.2 Close cabinet doors.

5.5.3 Loosen the actuator bracket screws and adjusting
screw nut. Move the actuator bracket up or down, and
the adjusting screw sideways, as needed to center the
adjusting screw on the over-travel stop (in center of
detent sleeve). Tighten the bracket screws.
5.5.4 Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure
on it. Tighten the adjusting screw nuts.
5.5.5 Test the operation with the doors open and then
again closed. Negative pressure inside the cabinet may
cause the doors 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 either door is
open and permit blasting when the doors are closed.
5.6 Pulse Pressure ‒ Figure 19
NOTICE
Do not pulse new dust collectors or
replacement cartridge until the cartridge is
properly seasoned, per Section 7.10. Pulsing
unseasoned cartridges can cause premature
cartridge failure and decrease efficiency of the
dust collector.
5.6.1 Adjust pulse pressure using the regulator
mounted on the pulse reservoir (refer to Figure 19).
Begin pulse at 60 psi. To adjust pressure, pull the knob
to unlock it, as shown in Figure 19, and then 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.
Figure 19
5.6.2 As the filter cartridge cakes with dust, it may be
necessary to pulse between blasting, per Section 6.2.4.
5.6.3 When pulsing alone does not adequately clean
the cartridge, increase pulse pressure in increments of 5
psi 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.
5.6.4 When the maximum pulse pressure of 90 psi is
attained, and additional pulsing as described in Section
6.2.4 does not increase visibility or decrease differential
pressure, replace the cartridge, per Section 7.9.
5.7 Cabinet Air-Inlet Damper
5.7.1 Once the damper 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, as noted in Section
5.4. Reclaimer pressure must be set before cabinet
pressure.
5.7.2 Using a manometer (as noted in Section 5.8 and
listed in Section 9.1) is the most accurate method of
monitoring and adjusting cabinet pressure. Following the
instructions packed with the manometer, start the
exhauster and insert the needle into a glove, and adjust
pressure using the 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 ON, 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 instructions
explain the processes for taking periodic readings and
show 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 0.5" to 1" lower than reading 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 instructions packed with the manometer
for preparing and operating 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 vertical 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 21.
5.8.6 Needle placement: Figure 20 shows the
manometer setup for taking both periodic and frequent
static-pressure readings.
Figure 20
5.8.6.1 Taking frequent readings using a permanent
fitting: A permanent fitting may be installed in the
reclaimer wall, as shown in Figure 20, 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 carry over of good media to the dust
collector.
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
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.
Figure 21
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"
and down the left column 1-3/4".
Static pressure is determined by adding
the columns together. In the example,
the static pressure is 3-1/2 ".
Refer to Paragraph 5.8.6.2.
When taking occasional
readings, position the
needle so the point is inside
the door opening. Carefully
close the door on the
needle.
Refer to Paragraph 5.8.6.1.
For taking frequent readings,
remove plug and install a
permanent fitting in the
coupling, as shown.
Reclaimers are for reference and
may differ from those shown.

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 21.
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 an approved respirator and
personal protection when servicing dust-laden
areas of the cabinet and dust collector, as well as
when emptying the container, could 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 gun and
nozzle, media hose, flex hose, wear plate, and all items
covered in this section. Adjust frequency of inspections
as needed, based on the following:
 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.
 Friability of media: Media that rapidly breaks
down require more maintenance to the cabinet’s
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 in
reclaimer and refill as necessary.
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.
6.1.3 Drain compressed-air filter: The cabinet is
equipped with a manual-drain air filter. Drain the filter at
least once a day, and more often if water is present.
Moist air inhibits the flow of media. Drain the air line and
receiver tank regularly. If the filter does not remove
enough moisture to keep media dry and flowing, it may
be necessary to install an air dryer or aftercooler in the
compressed-air supply line.
6.1.4 Inspect dust container: Empty the dust
container regularly. Start by inspecting the container at
least daily and when adding new media, then adjust
frequency based on usage, contamination, and friability
of the media.
1. Turn off the exhauster and unlatch the lid lock ring from
the dust container, as shown in Figure 22.
2. Pry off the lid from the container (the lid's flexible inlet
hose allows easy removal) and remove the container.
Figure 22
3. Tie off or otherwise seal the top of the liner and
remove it from the container. Dispose of the sealed liner
into a suitable disposal receptacle.

NOTE: Blasting media is usually nontoxic; however,
some 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.
4. Place a new liner inside the container and drape it
over the top edge. Reattach the container to the lid and
latch the lock ring, making sure the lid and clamp are
secure. Replacement liners are shown in Sections 9.11.
6.2 Daily Inspection During Blasting – Have
Someone Do the Following:
6.2.1 Inspect 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
Section 6.2.4 for additional pulsing.
6.2.2 Check exhaust air for dust: Dust discharge at
the 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.
6.2.3 Drain pulse reservoir ‒ Figure 23: Open the
petcock to drain water from the pulse reservoir before
and after each use.
Figure 23
6.2.4 Additional cartridge pulsing: 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.
1. Turn OFF exhauster.
2. 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.
3. Start the exhauster and let it run for 10 seconds or
until all airborne dust is cleared from the cabinet.
4. Repeat the process several times.
6.3 Weekly Inspection and Maintenance Before
Blasting with Air OFF
6.3.1 Inspect view-window cover lens: Inspect the
window cover lens. 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 BNP® gun assembly: 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. Replace parts as needed,
per Section 7.2.
6.3.4 Inspect media hose: Inspect media hose for
thin spots by pinching it every 6 to 12 inches. Replace
the hose when it becomes soft.
6.4 Weekly Inspection During Blasting – Have
Someone do the Following:
6.4.1 Inspect flex hoses: Inspect flex hoses for leaks
and wear.

7.0 SERVICE MAINTENANCE
WARNING
Prior to doing any maintenance or opening the
dust collector, the employer must meet required
OSHA standards, including but not limited to
29CFR 1910 for:
 Appropriate Respirator
 Protective Clothing
 Toxic and Hazardous Substances
 Fall Protection Lockout and Tagout
 Lockout and Tagout
All dust is hazardous to breath; toxicity and
health risk vary with type of dust generated by
blasting. Prolonged exposure to any dust can
result in serious lung disease and death. Short-
term exposure to toxic materials, such as lead
dust or dust from other heavy metals and
corrosives, can cause serious injury or death.
Identify all material that is being removed by
blasting and obtain a safety data sheet (SDS)
for the blast media. Waste dust in the collector
can cause serious injury or death through
inhalation, absorption, or ingestion. The
employer shall meet all OSHA requirements,
including but not limited to those for confined
space, combustible dust, fall protection, hazard
communication, and lockout and tagout
procedure for electrical and pneumatic supply.
7.1 Gloves
7.1.1 Special static-dissipating gloves are provided for
operator comfort. Gloves need to be replaced
periodically as they wear. The first sign of deterioration
may be excessive static shocks.
7.1.2 Band-clamp type: Band-clamp type gloves are
held in place by metal band clamps on the inside of the
cabinet. To replace, loosen the clamps with a
screwdriver, replace the gloves, and tighten the clamps.
7.1.3 Quick-change type, clampless installation:
Quick-change gloves are held in place using spring rings
sewn into the attachment end of the glove. To install, insert
the glove into the arm port so that one spring is on the
inside of the port and the other is on the outside,
sandwiching the arm port between both spring rings.
7.2 BNP® Gun Assembly ‒ Figure 24
Figure 24
7.2.1 Replace the nozzle when its orifice diameter has
worn 1/16" larger than its original size or when suction
diminishes noticeably. To change the nozzle, unscrew
the holding nut from the gun end, and pull the nozzle
from the gun. Inspect the nozzle O-ring and replace if
worn or damaged. Insert a new O-ring and nozzle,
placing the tapered end toward the jet. Screw the
holding nut onto the gun.
7.3 View-Window Cover Lens
7.3.1 Rapid frosting of the view window can be
avoided by directing ricocheting media away from the
window and by installing a cover lens on the inside
surface of the window. Using cover lenses prolongs the
life of the view window.
7.3.2 The best way to install a cover lens is to remove
the window from the cabinet. If, for some reason, it is not
practical to remove the window, the lens may be applied
with the window glass in place.
7.3.3 To install a cover lens, carefully remove the
adhesive backing making sure the adhesive remains on
the lens and apply the lens to the clean, dry, inner
surface of the view window. When the cover lens
becomes pitted or frosted, replace it.
The wider tapered-end of the
nozzle inserts into the gun.
