1.4 General Description
1.4.1 Refer to Figure 1 for the general arrangement of
the cabinet and power module. Components of the
cabinet assembly are shown in Figure 2 and
components of the power module are in Figure 3. 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. The Pulsar
IX-P pressure cabinet consists of two major
components.
1. Cabinet Enclosure
2. 900 cfm Power Module
1.4.2 Cabinet enclosure: Approximate work chamber
dimensions at the grate are:
54" wide x 40" deep x 45" high. The extended front
provides approximately 10 inches of additional depth at
the arm port.

1.4.3 Power module: The freestanding Pulsar IX-P
power module houses a 2-cu. ft. capacity 16" diameter
blast machine, 900 cfm reclaimer, and dual-cartridge
reverse-pulse dust collector.
1.5 Theory of Operation
1.5.1 Once the cabinet is correctly set up and turned
ON, the cabinet is ready for operation by actuation of the
foot pedal. Fully depressing down on the foot pedal
pressurizes the blast machine, causing media to be
propelled through the blast hose and out the nozzle.
After striking the object being blasted, the blast media,
fines, dust, and byproducts generated by blasting fall
through the grate into the cabinet hopper. These
particles are then drawn into the reclaimer for separation.
Dust and fines are first separated from reusable media
and pulled into the dust collector. Next, reusable media
is screened for oversize particles and returned to the
reclaimer for reuse. Dust and fines entering the dust
collector are removed from the air stream as they pass
through the filters, discharging clean air. When the foot
pedal is released, the blast machine depressurizes and
blasting stops. Media stored in the reclaimer
automatically refill the blast machine when blast
machine pressure equalizes and the pop-up valve drops
1.5.2 Dust Collector
1.5.2.1 The final stage of the recovery, reclaiming
process takes place in the dust collector. Dust and fines
drawn through the reclaimer are trapped on the outer
surface of the filter cartridges, and clean air is
discharged through the exhauster.

1.5.2.2 At regular, timed intervals, the dust-collector
filter cartridges are cleaned by a pulse of high-velocity
compressed air expanding against the inner surface of
the cartridges. The expanding air momentarily reverses
air flow through the cartridges releasing trapped dust.
The dust particles fall away from the cartridges into the
hopper for removal.
1.5.2.3 The pulse interval is controlled by a timer
located inside the sequence panel. The timer controls
the ON time (the length of time for each pulse) and OFF
time (the length of time between each pulse). The ON
time should never be adjusted. The lower the setting for
the OFF time, the shorter the length of time between
pulses.
1.5.2.4 A toggle switch (sequence switch) located on
the sequence panel cover, enables or disables the
timing sequence. If the sequence switch is kept ON, the
timing sequence energizes when the exhauster is turned
ON, and the cartridges are automatically pulsed when
the exhauster is running. If the switch is OFF, the timer
does not energize, and the cartridges are not pulsed.
NOTICE
Do not pulse new dust collectors or
replacement cartridges until the cartridges are
properly seasoned, per Section 7.9. Pulsing
unseasoned cartridges can decrease the
efficiency of dust collectors and cause
premature cartridge failure.
1.6 Blast Machine and Controls
1.6.1 Clemco certifies its blast machines (pressure
vessels) to conform to the ASME (American Society of
Mechanical Engineers) Boiler and Pressure Vessel
Code, Section VIII, Division 1. It is the owner’s
responsibility to maintain the integrity of the vessel in
accordance with state regulations. Regulations may
include regular inspection and hydrostatic testing as
described in National Board inspection code and
jurisdictional regulations and/or laws.
WARNING
Welding, grinding, or drilling on the blast
machine can weaken the vessel. Compressed-
air pressure can cause a weakened blast
machine to rupture, resulting in death or
serious injury. Welding, grinding, or drilling on
the vessel without a National Board R Stamp
voids the Clemco ASME certification.
1.6.2 All welding repairs to the vessel must be
performed by certified welders at shops holding a
National Board R stamp. Welding performed by any
welder not properly qualified per the ASME code voids
the Clemco ASME certification.
1.6.3 Do not exceed the maximum working pressure
rating (PSI) of the blast machine. The maximum
pressure rating is stamped into the ASME nameplate,
which is welded to the side of the vessel.
WARNING
Excessive compressed-air pressure can cause
a blast machine to rupture. To prevent serious
injury or death, do not exceed the rated
pressure of the blast machine.
1.6.4 OSHA does not require pressure-relief valves on
blast machines when air compressors supplying air to
the blast machines are built to American Society of
Mechanical Engineers Boiler and Pressure Vessel
Code, Section VIII, Division 1 and comply with OSHA
regulation 29 CFR 1910.169, which refers to the ASME
code when describing the necessity of pressure-relief
valves on compressed air equipment. DO NOT operate
blast machines with air compressors that are not
equipped with properly functioning pressure-relief valves
with maximum pressure less than or equal to the
maximum-allowable working pressure (MAWP) stamped
on the vessel nameplate.
1.6.5 When the cabinet is set up, the blast machine is
ready to blast by actuating the foot pedal. Pressing the
foot pedal opens the normally closed main inlet regulator
and closes the normally open outlet valve. The incoming
air pressurizes the blast machine, and blasting begins.
When pressure on the foot pedal is released, the blast
machine depressurizes and blasting stops.
1.7 Nozzle Options
1.7.1 Unless otherwise specified at the time of
purchase, the cabinet is provided with a 3/16" orifice
tungsten carbide nozzle. Optional 1/8" and 1/4" orifice
nozzles are also available.
1.7.2 Nozzles with an orifice larger than those
recommended could cause air leakage from the cabinet
and impair recovery from the cabinet hopper.
1.7.3 Use boron carbide nozzles when blasting with
aggressive media noted in Section 1.11.4. Nozzles lined
with boron carbide extend nozzle wear life. Refer to
Section 9.1: Optional Accessories.

PULSAR® IX-P PRESSURE BLAST CABINET Page 6
© 2019 CLEMCO INDUSTRIES CORP.  www.clemcoindustries.com  Manual No. 23430, Rev. F, 07/19
1.8 HEPA (high efficiency particulate air) Filter
1.8.1 Optional HEPA afterfilter provides additional
filtration. A HEPA filter must be used when removing
lead 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 or user’s responsibility to ensure all
emissions are safe to breath.
1.9 Optional Reclaimer Liners
1.9.1 Replaceable rubber reclaimer-liners prolong
service life of the reclaimer. They should be installed
when using silicon carbide, aluminum oxide, or other
aggressive media, as noted in Section 1.11.4. Rubber
reclaimer liners are shown in Section 9.1.3: Optional
Accessories, Figure 43.
1.10 Metering Valve Options
1.10.1 Unless specified at the time of purchase,
cabinets are supplied with a fine-mesh Sentinel Metering
Valve. The valve is for use with 50-mesh and finer
media, and #10 and finer glass bead. The optional
Sentinel Metering Valve is recommended when using
media coarser than 50-mesh. Conversions kits listed in
Section 9.1 easily convert the valves.
1.11 Blasting Media
NOTE: Always use media specifically manufactured for
blasting and that 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. Always obtain safety data sheet (SDS) for the
blasting abrasive prior to blasting and identify material
being removed by blasting, paying particular attention to
worker health risks and presence of any hazardous/toxic
substances.
1.11.1 Most common reusable media (with the
appropriate metering valve as noted in Paragraph 1.9)
specifically manufactured for blasting can be used in
ZERO Pulsar® cabinets. The listing of media sizes
shown in this section and in Figure 4 are provided as a
guideline only. The guideline is based on standard 3/16
orifice 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 factors 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 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.
1.11.2 Steel shot and Steel grit: Steel shot S-170 to
S-70 or steel grit 80-mesh to 120-mesh may be used in
Pulsar® IX-P cabinets configured for using steel media.
Using steel media requires a smaller diameter conveying
hose (usually reduced one size from standard. Rubber
curtains should be used to protect the cabinet walls from
peening and rapid wear. For these applications, cabinets
can be ordered with reduced-size flex hose appropriately
sized for steel grit, and with rubber curtains installed. They
may also be field installed later. See Section 9.1: Optional
Accessories.
1.11.3 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 because they rapidly breakdown and
are not recyclable.
1.11.4 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.

PULSAR® IX-P PRESSURE BLAST CABINET Page 7
© 2019 CLEMCO INDUSTRIES CORP.  www.clemcoindustries.com  Manual No. 23430, Rev. F, 07/19
This guideline to media selection is based on standard 3/16” orifice nozzle and average conditions, such as, air pressure, media-air
mixture, visibility, contamination of parts being cleaned, humidity, media friability, reclaimer cleaning rate, etc. As
a rule, larger nozzles deliver more media, requiring higher performance from the reclaimer. Larger nozzles
decrease the maximum mesh size of media from those recommended. Media that is finer than those
recommended may decrease visibility and, 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.

* Standard reclaimer inlets.
Figure 4
When using aggressive media only occasionally, install
an optional aluminum oxide kit, which includes rubber
curtains for the cabinet interior and a boron carbide-
lined nozzle. When using aggressive media on a regular
basis, install the aluminum oxide kit and a fully-rubber-
lined reclaimer. NOTE Rubber-lined reclaimers are
available as factory-installed items or field-installed
liners can be installed later on reclaimers if they have
removable tops and are designed to accept liners.
Nozzles lined with boron carbide extend nozzle wear
life. See Section 9.1 Optional Accessories.
1.11.5 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 thoroughly drying
and breaking up any clumps.
1.11.6 Lightweight and fine-mesh media: When
using lightweight (such as agricultural) media or fine-
mesh (180-mesh and finer) media, the reclaimer inlet
baffle may need to be removed to retain media and
avoid carry over. On reclaimer models with bolt-on
removable topes, baffle removal and replacement is
easily accomplished. Reclaimers with welded-on tops
require grinding to remove the baffle and once it is
removed, it cannot be replaced.
1.11.7 Plastic media: Plastic media requires a blast
machine with a 60-degree conical bottom. Refer to
Clemco’s AEROLYTE cabinet brand.
1.11.8 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). Refer to Clemco’s AEROLYTE cabinet line
for cabinets that are specifically designed for use with
bicarbonate of soda.
1.12 Compressed-Air Requirements
1.12.1 The size of the compressor required to operate
the cabinet depends on the size of the nozzle and
blasting pressure. Unless otherwise specified, cabinets
are supplied with a 3/16" orifice nozzle. The table in
Figure 5 shows air consumption of nozzles when new. It
does not show the recommended compressor size. As
nozzles wear, they will consume up to 70% to 80%
more air. Consult with a compressor supplier for a
suggested compressor size based on the air
consumption.
Compressed-Air Consumption *(cfm)
Nozzle Air Pressure (psi)
size 50 60 70 80
1/8" 11 13 15 17
3/16" 26 30 33 38
1/4" 47 54 61 68
* Figures are approximate and for reference only,
and may vary for different working conditions.
Several variables, including media flow and nozzle
wear, affect cfm consumption.
Figure 5
1.12.2 The air filter at the blast machine inlet removes
condensed water from the compressed air. The filter
automatically drains when moisture fills the bowl to a
certain level. Its use is especially important in areas of
high humidity or when fine-mesh media are used.
Moisture causes media to clump and inhibits free flow
through the metering valve. If the filter does not remove
enough moisture to keep media dry and flowing, it may
be necessary to install an air dryer or aftercooler in the
air-supply line.

access around the operator station, all doors, service
areas, and for efficient handling of large parts. Ideally,
the cabinet and power module are positioned so the flex
(conveying) hose and blast hose are arranged with as
few beds as possible. Determine the best location for
both modules, and position them before final assembly.
2.2 Connect Conveying (Flex) Hose
Installation Notes:
To prevent excessive hose wear, avoid sharp bends.
It is easier to slip the hose over the connectors and to
create a tighter seal if the first two or three inches of
wire is removed from the inside of the hose. Use care
not to damage the hose. The hose wire helps dissipate
static electricity in the conveying hose, and helps
ground each segment. For the hose wire to dissipate
static electricity, the wire must touch the metal of each
segment.
2.2.1 Connect the 6" diameter flex hose between the
cabinet hopper and reclaimer inlet, as shown in Figure 1
2.2.2 Connect the 7" diameter flex hose between the
reclaimer outlet and the dust-collector inlet, as shown in
Figure 2. This hose is sometimes removed for shipping.
2.2.3 Clamp the flex hoses securely in position with
worm clamps provided.
2.3 Connect Blast Hose ‒ Figure 6
WARNING
Hose disconnection while under pressure can
cause serious injury or death. Use safety lock
pins or safety wire to lock twist-on 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.
2.3.1 Connect the blast hose from the cabinet hopper
to the coupling at the bottom of the blast machine. Make
sure coupling gaskets are in place and couplings are
secured with safety lock pins.
Once installed, remove slack from the safety cable.

2.8 Connect Compressed-Air Supply Line
WARNING
Failure to observe the following before
connecting the equipment to the compressed-
air source can cause serious injury or death
from the sudden release of compressed air.
 Lockout and tagout the compressed-air
supply.
 Bleed the compressed-air supply line.
2.8.1 Apply thread sealant to the male threads of an
air fitting that is compatible with the air-supply hose
fitting, as noted in Section 2.8.2, and install it onto the 1-
NPT air filter located at the blast machine inlet, as
shown in Figure 10. Note that the style of connection
shown is for reference only.
WARNING
Hose disconnection while under pressure can
cause serious injury or death. Use safety lock-
pins or safety wire to lock twist-on claw type
couplings together and prevent accidental
separation, and safety cables to prevent hose
from whipping should separation occur.
2.8.2 Install an isolation valve at the air source to
enable depressurization for service, and connect a 1" ID
or larger air line from the air source to the air filter on the
blast machine. A smaller diameter hose may reduce
blasting efficiency.
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. Doing so enables
depressurization of the compressed-air lines
before performing maintenance.
2.9 Ground the Cabinet and Dust Collector
2.9.1 To prevent static electricity build up, attach an
external grounded wire from an earth ground to the
grounding lug on the rear leg of the cabinet and a bolt

2.10 Connect Electrical Service
WARNING
Lockout and tagout the electrical supply before
performing any electrical service. Shorting
electrical components can cause death, serious
injury from electrical shock, or equipment
damage. All electrical work, or any work done
inside an electrical panel, must be performed by
qualified electricians, and comply with
applicable codes.
NOTE: Wiring schematics are stored in the electrical
panel. Refer to the schematic when making electrical
connections. After wiring is completed, keep the
schematic with the manual for future reference and for
electrical replacement parts.
2.10.1 Where possible, all wiring has been completed
at the factory. An electrician needs to provide service
from the user-provided disconnect to the motor starter in
the electrical panel mounted on the side of the dust
collector, and to connect the conduit and wiring from the
junction box on the cabinet to the electrical panel.
2.10.2 The choice of 230 or 460 voltage must be made
at time of order, so that the control panel and wiring is
supplied accordingly. Unless specified otherwise, the
motor and control panel are wired for 230 volts. A wiring
schematic for the cabinet and accessories is stowed in
the panel.
2.11 Check Motor Rotation
2.11.1 After the wiring is completed, observe the
subsequent warning, and check the motor rotation. To
check rotation, jog the starter (momentarily turn switch ON
and OFF). This will cause the motor to rotate slowly. Look
through the slots in the fan housing on the motor where
rotation of the fan can be easily observed. Proper rotation
is indicated by the arrow on the exhauster housing. The
fan should rotate toward the exhauster outlet.
WARNING
Do not look into the reclaimer exhauster outlet
while the paddle wheel is turning. Injury to the
eye or face can occur from objects ejected from
the exhauster.
2.12 Check Amperage
2.12.1 Check the amperage on initial start up. If the
motor draws excessive amperage, gradually close the
dust-collector outlet damper until the amperage is within
the specifications shown on the motor plate. Refer to
Section 5.3 for adjustment procedure.
2.13 Final Assembly
2.13.1 Insert a short length of 3/8" tubing into the
automatic drain at the bottom of the compressed-air
filter, as shown in Figure 11, and place the other end
into a pail. When the filter automatically drains, the water
will drain into the pail.
Figure 11
2.13.2 Position the foot pedal on the floor at the front of
the cabinet.
2.13.3 A package of five view-window cover lenses is
supplied with the cabinet. Install a cover lens, per
Section 7.2. When the cover lens becomes pitted or
frosted, replace it.
3.0 FIELD INSTALLED ACCESSORIES

and rear walls (refer to Section 3.2 for curtain
installation), a boron carbide lined 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 ‒ Figure 12
3.2.1 Match curtains to corresponding walls and
doors. When overlapping curtains, make sure the
overlaps are on the correct end of the curtains.
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 edges of the
curtains should be aligned with the top of the cabinet,
and the front curtain should be aligned around the view
window. Remove the curtains, and drill a .187" (3/16")
diameter hole at each point marked. Install the curtains
using the fasteners provided (machine screw, flat
washer, lock washer and nut) at each grommet. The flat
washer is used between the screw head and curtain
grommet.
For the front walls, place the batten strip over the
curtains and clamp it in position on the front slope above
the break, as shown in Figure 12. Match drill .187"
(3/16") diameter holes through the rubber and cabinet
front at each batten hole. To install the batten, insert
#10-24 x 1" round-head machine screws through the
cabinet front, curtain, and batten. Install lock washers
and nuts from inside the cabinet and tighten securely.
Figure 12
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 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.
3.3 Manometer
The optional manometer kit is listed in Section 9.1.
3.3.1 Consistent static pressure is necessary for
precise media separation, as the reclaimer's efficiency is
achieved by a centrifugal balance of air flow, particle
weight, and size. The manometer measures static
pressure. Reclaimer static pressure is set by adjusting
the dust-collector damper. Refer to Section 5.3 to adjust
static pressure. Refer to Section 5.9 for instructions on
using the manometer.
3.4 Armrest
3.4.1 Assemble the armrest and mounting brackets,
as shown in Figure 13.
Cabinet shown for reference.
Figure 13
3.4.2 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.
3.4.3 Drill a 3/8" hole at both locations and mount the
armrest using 5/16 cap screw, washers, and nuts. Install
the bolts from inside the cabinet to protect the threads from

3.4.5 Loosen the fasteners on the slotted bracket and
raise or lower the armrest to a comfortable position.
3.5 Turntable with Workcar and Track
Installation note: The track may be placed on either side
of the cabinet, allowing entry through either the right side
or left side door; the right side is shown in the illustrations.
When installing the inside track, place it so the stops are
opposite the entry door, as shown in Figure 15.
These instructions cover field installation of the 500 lb
capacity track and workcar with turntable. If the track
was ordered with the cabinet, it is partially assembled at
the factory, Disregard the instructions that do not apply.
Refer to Figure 14 for arrangement of the major
components.
3.5.1 Components of the turntable and track assembly
are shown in Figure 14. The assembly consists of:
1. The inside track assembly, which is placed inside
the cabinet.
2. The hinged track extension attaches to the support
table and swings up to clear the door.
3. The track support table.
4. Turntable and workcar assembly.
Figure 14
3.5.2 Place the inside track in the cabinet over the
existing grate as shown in Figure 11.
Figure 15
3.5.3 With the door open, position the track support
table and extension as shown in Figure 16. When the
hinged extension is lowered, the extension tracks must
rest on the angled locating supports welded to the
bottom of the inside tracks, and butt against the inside
tracks.
Figure 16
3.5.4 Loosen the leveling-pad lock nuts and raise or
lower the pads, as needed to adjust the height of the
table, to make sure that the inside and outside tracks
are aligned, that the hinged extension rest evenly on the
support angles when the extension is lowered, and that
the table is level.
3.5.5 Raise the track extension, and then open and
close the door to make sure they function correctly.
When certain the table and tracks are aligned and level,
and that the workcar moves smoothly on all tracks,
tighten the leveling-pad lock nuts and anchor the support
table to the floor through the holes in the leveling pads.
3.6 Dust-Collector Differential-Pressure Gauge
3.6.1 The differential-pressure gauge measures
pressure drop across the filter cartridges. The gauge
reading is the best way to monitor cleaning efficiency
and dust buildup on the cartridges.
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

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.
4.0 OPERATION
4.1 Season Filter Cartridges Per Section 7.9
NOTICE
Do not pulse new dust collectors or
replacement cartridges until the cartridges are
properly seasoned, per Section 7.9. Pulsing
unseasoned cartridges can decrease the
efficiency of dust collectors and cause
premature cartridge failure.
4.2 Loading Media
4.2.1 Media capacity: Media capacity of the Pulsar
IX-P pressure cabinet is approximately 2 cu. ft. Full
capacity is when media is at level of the pop-up valve.
4.2.2 Media loading: With the exhauster OFF, add
clean dry media by pouring it into the reclaimer hopper
through the reclaimer door. Do not pour media directly
into the cabinet hopper, as overfilling or blockage
may occur. Overfilling will result in media carry over to
the dust collector and possible blockage in conveying
hose. Refill only after all media has been recovered from
the cabinet.

4.3 Unloading Media
4.3.1 To empty the cabinet and blast machine of
media, blow-off the cabinet interior and run the
exhauster until all media is recovered from the cabinet.
Turn off the exhauster, and reduce pressure to 40 psi.
Place an empty container, such as a bucket, on the
cabinet grating. Remove the nozzle and nozzle
washer, close the door, close the choke valve and
press the foot pedal. Direct media flow into the
container. Empty the container when full or before it is
too heavy to manage, and repeat the process until the
machine is empty. Clean the nozzle holder threads
before reinstalling the nozzle washer and nozzle. If
complete purging of media is required, use a vacuum
to remove media residue in the cabinet hopper and
blast machine head.
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 can cause
them to shift or topple, and cause severe injury.
This is especially important with the use of
turntables and turntables with tracks.
4.4.1 Parts must be free of oil, water, grease, or other
contaminants that will clump media or clog filters. If parts
are oily or greasy, degrease and dry them prior to
blasting.
4.4.2 Load and unload parts through either door.
4.4.3 When blasting small parts or objects having
small pieces that could become dislodged and fall off,
place an appropriately sized screen over the grate (or
under the grate when frequently blasting small parts) to
prevent parts from falling into the hopper. If an object
should fall through the grate, stop blasting immediately
and retrieve it.
4.4.4 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 the 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. Refer to troubleshooting Sections
8.14 and 8.15 and identify source of leak.
4.5.1 Slowly open the air valve on the air supply to the
cabinet. Check for air leaks on the initial startup and
periodically thereafter.
4.5.2 After the filter cartridges are seasoned per
Section 7.9, 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 push-button
switches, located on the cabinet front, performs both
functions.
4.5.4 Load parts. If parts are oily or greasy, degrease
and dry them prior to blasting.
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 blast gloves.
4.5.8 To blast, hold the nozzle holder or hose just
behind the nozzle holder, point the nozzle toward the
object to be blasted, and apply pressure to the foot
pedal. Blasting will begin almost immediately.

PULSAR® IX-P PRESSURE BLAST CABINET Page 16

WARNING
Shut down the cabinet immediately if dust leaks
are detected from the dust collector or cabinet.
Make sure the dust-collector filters are correctly
seated and not worn or damaged. Prolonged
breathing of any dust can result in serious lung
disease or death. Short-term ingestion of toxic
dust, such as lead, poses an immediate danger
to health. Toxicity and health risks vary with
type of media and dust generated by blasting.
Identify all material being removed by blasting
and obtain a safety data sheet (SDS) for the
blast media.
4.5.9 Adjust the pilot pressure regulator to the
required blasting pressure, per Section 5.1. The
regulator is located on the top-left side of the cabinet.
NOTE: Pressure registers on the gauge only while
blasting.
NOTE: When holding parts off the grate, use a solid
conductive backrest to support the part. Without this
assist, especially with longer blasting operations, the
operator will tire easily from resisting blast pressure, and
static electricity could build up in the ungrounded part
and cause static shocks. Whenever possible, avoid
holding small parts that require blasting into the glove.
4.5.10 If an object should fall through the grate, stop
blasting immediately and retrieve it.
4.6 Operation and Function of the Choke Valve
Figure 18
4.6.1 Always fully open the choke valve while blasting;
open is when the handle is vertical and aligned with the
piping, as shown in Figure 18.
4.6.2 Closing the choke valve while blasting lowers
pressure in the pusher line from the pressure in the
vessel. Closing the valve forces media through the
metering valve to clear minor blockage, such as damp
media, or it is used to rapidly empty the machine to
change media.
NOTICE
Do not blast with choke valve closed or partially
closed. Prolonged blasting with the choke valve
partially closed will accelerate wear on the
metering valve.
Figure 18
4.7 Blasting Technique
4.7.1 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 nozzle
approximately 6" from the surface of the part.
4.8 Stop Blasting
4.8.1 To stop blasting, remove pressure from the foot
pedal. The blast machine will depressurize each time
the foot pedal is released.
4.8.2 The blast machine refills with media stored in
the reclaimer each time the foot pedal is released.
Refilling takes approximately 15 seconds.
4.8.3 Use the blow-off nozzle to blow media off parts.
4.8.4 Keep doors closed and exhauster running until
the cabinet is clear of all airborne dust.
4.8.5 Unload parts.
4.9 Shutdown
4.9.1 Shut off the air-supply valve, bleed the air-
supply line, and drain the compressed-air filter and pulse
reservoirs.
4.9.2 Switch OFF the lights and exhauster.

5.0 ADJUSTMENTS
5.1 Blasting Pressure (pilot regulator)
5.1.1 The pilot regulator, located left of the view
window, enables the user to adjust blasting pressure to
suit the application. The suitable pressure for most
purposes is 80 psi. Lower pressures may be required on
delicate substrates and will reduce media breakdown.
Higher pressure may be required for difficult blasting
jobs on durable substrates, but will increase media
breakdown. Optimal production can only be achieved
when pressure is carefully monitored.
5.1.2 When blasting below 40 psi, first pressurize the
blast machine at 40 psi and then turn the pressure to the
required setting before blasting the part. If the initial
pressure is below 40 psi, the pop-up valve may not seal.
5.1.3 Pressure registers on the gauge only while
blasting. To adjust pressure, begin blasting and hold the
nozzle securely with the right hand. Use the left hand to
unlock the knob by pulling it out, as shown in Figure 19,
Turn it clockwise to increase pressure or counterclockwise
to decrease pressure. Once operating pressure is set,
push the knob in to lock it and maintain the setting.
NOTE: The operator may find it easier to adjust
pressure if the knob is unlocked before blasting and
when pressure is set, stop blasting to lock the knob.
Figure 19
5.2 Media Metering (media flow) – Figure 20
These instructions and the illustration in Figure 20 are for
a standard cabinet with Sentinel metering valve. Optional
metering valves may function differently, but the process
is similar. Refer to the metering valve operations manual
for the operation of the valve provided.
OPEN
CLOSE
Figure 20
5.2.1 Adjust media flow using the metering valve
located at the bottom of the blast machine. The valve is
closed when the handle is fully to the right. To adjust,
begin with the valve closed, press the foot pedal and
have someone slowly move the handle to the left to
increase media flow. Allow time for the flow to stabilize
before further adjusting. The valve is fully open when the
handle is at the full-left position. The optimum flow rate
depends on the type and size of media and blasting
pressure, and can best be determined by experience.
Use as little media as possible to do the job while
maintaining the best cleaning rate. Generally, with the
correct mixture, abrasive can be seen as light
discoloration as it exits the nozzle.
5.3 Reclaimer Static Pressure (dust-collector
outlet damper)
5.3.1 Static pressure settings vary with size, weight,
and type of media.
5.3.2 Adjust static pressure by opening or closing the
outlet damper located above the dust collector, refer to
Figure 21. 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
carry-over (usable media carried into the dust collector)

media through several cycles and inspect media in the
reclaimer and dust in the dust containers. Open the
damper only as far as necessary to obtain a balance of
maximum dust removal without good-media carry over.
Figure 21
5.3.3 A manometer is useful for adjusting and
monitoring static pressure. The manometer kit is listed
under Optional Accessories in Section 9.1. Refer to
Section 5.9 for manometer operation. The following are
static-pressure starting points for given media. Static
pressure may need to be lower with finer media or
higher with coarser media. If a manometer is not
available, begin with the damper about half open (handle
pointing toward 45o on the label). 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 Sections 5.3.2.
Continue adjusting static pressure until optimum media
cleaning without carry over is attained.
Glass Bead No. 4 and 7 ................................ 3" – 3-1/2"
Glass Bead No. 8 to 12 ................................. 2-1/2" – 3"
Aluminum Oxide 46-Mesh to 80-Mesh ................ 4" – 5"
Aluminum Oxide 80-Mesh to 180-Mesh ........ 2-1/2" – 3"
*Steel Grit, 50-Mesh to 120-Mesh ...................... 6" – 7"
*Steel Shot S-170 to S-70 .................................. 6" – 7"
*Refer to Section 1.11 for media limitations.
5.3.4 After adjusting the damper, and carry over or
excessive dust in the media continues, adjust the vortex
cylinder per Section 5.4. Vortex cylinder adjustment is
usually required only when using 180-mesh and finer
media, or lightweight media.
5.3.5 As dust accumulates on the outer surface of the
cartridges, static pressure drops, requiring additional
pulsing of the cartridges, as described in Section 5.7, or
an increase in pulse pressure, per Section 5.6. When
pulsing no longer maintains the necessary static
pressure, readjust the damper.
5.4 Externally Adjustable Vortex Cylinder
The vortex cylinder fine-tunes media separation. Before
adjusting the cylinder, adjust the damper on the dust
collector to increase or decrease static pressure per
Section 5.3. Once the damper is adjusted, adjust the
cylinder.
5.4.1 The vortex cylinder is located atop the reclaimer
where the flex hose connects. Adjustments are made by
loosening the handle's tensioning knob and moving the
handle to achieve the correct setting. When the correct
setting is established, tighten the locking knob to prevent
movement. Start with the lever slightly to the right (about
1 o’clock as shown in Figure 22) of the vertical position.
Figure 22
5.4.2 To remove more fines: (Too much dust in
media) Raise the cylinder by moving the lever left toward
"COARSE" in 1/4" increments at the indicator plate.
Allow the media to go through several blast cycles
before determining if further adjustment is needed.
5.4.3 To remove fewer fines: (Excessive usable
media is carried to the dust collector) Lower the vortex
cylinder by moving the lever right toward "FINE" in 1/4"
increments at the indicator plate. NOTE: If the cylinder is
lowered too far, the reclaimer will again begin to allow
usable media to be carried over and cause abnormally
high static pressure.
5.4.4 When using media finer than 180-mesh, the inlet
baffle of the reclaimer may need to be removed. Refer to
Section 1.11.6.

5.5 Door Interlocks ‒ Figure 23
WARNING
Never attempt to override the interlock system.
Doing so can result in injury from unexpected
blasting.
5.5.1 The door interlocks disable the blasting control
circuit when 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.
Figure 23
5.5.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator bracket up or
down, and the adjusting screw sideways, to center the
screw on the over-travel stop. Tighten the bracket screws.
5.5.4 Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure
on it. Tighten the adjusting screw nuts.
5.5.5 Test the operation with the doors open and then
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 Dust-Collector Pulse Pressure ‒ Figure 24
NOTICE
Do not pulse new dust collectors or
replacement cartridges until the cartridges are
properly seasoned, per Section 7.9. Pulsing
unseasoned cartridges can decrease the
efficiency of dust collectors and cause
premature cartridge failure.
5.6.1 Adjust pulse pressure using the regulator
mounted on the dust-collector body. Begin pulsing at 60
psi. To adjust pressure, pull the knob to unlock it, as
shown in Figure 24, 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 24
5.6.2 When pulsing does not adequately clean the
cartridges, increase pulse pressure in increments of 5 psi
to 10 psi until the maximum of 90 psi is reached. As dust
cakes on the cartridges, differential pressure increases.
Using a gauge to measure the differential pressure is a
good way to tell if the cartridges are heavily caked.
5.6.3 When the maximum pulse pressure of 90 psi is
attained, and additional pulsing as described in Section
5.7 does not decrease differential pressure or increase
visibility, replace the cartridges per Section 7.8.
