medium flat-blade screwdriver

1.2 Step-by-Step Procedure
Step 1: Unwrap and remove cabinet
and the components from the pallet.
Step 2: Most cabinet systems are
shipped with the reclaimer mounted to
the cabinet. If your system was
shipped with the reclaimer NOT
installed, install the reclaimer as
follows:
a. Lift the reclaimer assembly and
set in place against the rear of
the cabinet so that the slots in
the reclaimer bracket set down
on the “Z-strip”.
b. Push the reclaimer assembly up
against the rear of the cabinet so
that the mounting bolts
protruding from the rear wall of
the cabinet are inserted into the
keyhole slots in the bracket. See
Figure 2.

Figure 2. Reclaimer Mounting
Step 4: Attach one end of the conveying
hose to the cabinet hose adapter.
Attach the other end of the hose to the
reclaimer inlet. See Figure 3. Use
supplied hose clamp to make
connections airtight.

Step 3: With the reclaimer in position,
tighten the bolts.

position as shown in Figure 4.
Figure 5. Air Hose Assembly to Pipe
String Assembly
Step 9: Install the safety pin through
the holes in both halves of each quick
coupling. See Figure 5.
Step 10: Connect the harness ¼” O.D.
control tubing to the exhaust valve and
air valve fittings as shown in Figure 5.
Making sure the connection is tight.
Figure 4. Pressure Vessel Installation

Step 11: Connect the 1” exhaust hose
from the MG-78 exhaust valve to the
hose barb located at the reclaimer inlet.

Step 6: Adjust the leveling bolts on the
pressure vessel legs so that the weight
of the assembly is evenly distributed on
the floor and the hopper flange mates
with the pressure vessel.

Step 12: Connect the blast hose quick
coupling as shown in Figure 6 to the
tank coupling below the Sure-Flo Media
Regulator. Install the safety pin.

WARNING
Be sure to insert the safety pins into
the two halves of each quick
coupling to lock them together.

Step 14: Slide out the terminal strip
plate as shown in Figure 7.

Figure 7. Terminal Strip
Figure 6. Hose/Coupling Connection
Steps 13 and 18 apply to singlephase systems only.

Step 15: Insert the free end of the fan
motor cord into the strain relief on the
top of the electrical box, as shown in
Figure 8.

If your system includes a dust collector,
make the electrical connection between
the fan motor and the cabinet electrical
control box as follows:
WARNING
Be sure that the cabinet supply cord
is disconnected before you start this
procedure.
Step 13: Remove the four screws from
the corners of the control box cover.

Figure 8. Strain Relief
Step 16: Pull about 16 inches of cord
into the electrical box.

Step 17: Notice that the fan motor cord
wires are numbered. Connect each
wire to the terminal of the same
number.

The single phase electrical schematics
shown in Figure 9 and Figure 10 also
appear on the back of the control box
cover.

Step 18: Replace the terminal strip
plate and control box cover. Tighten the
strain relief where the connecting cord
enters the control box.

Consult the schematic that applies to
the specific type of electrical power that
will be supplied to the cabinet. Your
power supply must match the label
power supply of the cabinet and dust
collector fan motor.

Figure 9 and Figure 10.

Empire Abrasive Equipment Company

Step 19: If your system has a fan and
dust bag, fasten the dust bag to the fan
outlet and secure with the clamp
provided.
Step 20: Install the dust hose between
the reclaimer outlet and the dust
collector inlet.

Step 21: Secure the hose ends with the
clamps provided.
Step 22: Connect your system to
utilities as described in the Installation
section following.

2.0 Installation
Your Pro-Finish® system may arrive fully assembled or in easily assembled modular
packages. All equipment must be well grounded and mounted on a level surface. DO
NOT install your Pro-Finish® system on a wooden floor, a rubber mat, or a floor subject
to wet conditions.
IMPORTANT
All electrical connections to the Pro-Finish® cabinet should be made by a
qualified electrician and must adhere to the codes, standards, and procedures
specified by the authority having jurisdiction.
The customer is responsible for providing appropriate disconnecting means
adjacent to the equipment for each incoming power circuit.

2.1 Installing the Optional Dust Collector
If your system includes a dust collector,
you should install it before your install
the cabinet, because in many
instances, the dust collector is located
behind the cabinet. Install the dust
collector as follows:
Step 1: Place the dust collector on a
level surface behind or adjacent to your
Pro-Finish® Cabinet location.

Step 3: Allow enough space for the
cabinet doors to open freely. Also allow
enough room to remove the dust from
the dust collector hopper.
Step 4: Stabilize the dust collector by
adjusting its leveling bolts to
compensate for any unevenness in the
supporting floor.
Step 5: A separate ¼” air line is
supplied for the dust collector shaker
mechanism. Attach the free end of this
air line to the dust collector compressed
air inlet connection.

Step 2: Be sure the access door and
pneumatic shaker control on the dust
collector are easily accessible and the
dust hose inlet is directed toward the
cabinet.

2.2 Installing the System
Step 1: Place the cabinet on a level
surface. Ensure that there is enough
space around the system for easy
access to components. There should be
enough space for work pieces to be
easily loaded and unloaded through the
cabinet doors.

Step 2: Stabilize the cabinet by
adjusting its leveling bolts to
compensate for any unevenness in the
supporting floor.

2.3 Electrical Connections
The standard power supply for the 400
CFM (1 HP) systems is 115-volts/60
cycle/single phase. The standard
electrical supply for 600 CFM (1 ½ HP)
and 900 CFM (2 HP) systems is 230volts/60cycle/single phase. Cabinets
are also available prewired for the
optional power supplies listed in Section
7.0 Options and Accessories. Standard
single-phase systems are supplied with
a line cord (except for systems delivered
to Canada).

the size of the nozzle you are using and
the desired blast pressure. The chart
lists the minimum air requirements in
SCFM for various nozzles and
pressures.

Step 1: Using the following two charts
to determine the proper air volume
needed for your Pro-Finish® system.
The volume of air required for efficient
operation of your system depends on

Step 2: Use the chart below to
determine the size of the air line needed
for your cabinet. Even when the
compressor is properly sized, the air
line that connects it to your cabinet
must be large enough to avoid a large
pressure drop, which can cause
inefficient blasting.

Example: Your systems includes:
(a) A 125 foot long air line which
requires a 1” line (according to
the table).
(b) An air volume of 80 CFM, which
requires a 1-1/4” line size
Choose the larger line size (1-1/4”).

Up to 95
95 to 190
190 to 350

Air Volume (SCFM)
13 to 38
38 to 59
59 to 85

IMPORTANT
To operate properly, your Pro-Finish® system requires clean, dry air. Moisture or
oil in the compressed air supply can contaminate the abrasive, which can
prevent it from flowing freely and cause inefficient blasting. Though your
system is equipped with a general purpose filter to remove small amounts of
condensed water and oil from compressed air supply, this filter is not designed
to clean grossly contaminated air.

3.0 General Equipment Operation
3.1 Media Selection and Use
Proper media selection strongly
influences the efficiency of your
blasting operation. Your choice of
media depends on the kind of job to be
done (cleaning, deburring,
smoothing sharp edges, paint removal,
preparation for coatings, etc.) The size
of the media depends on the results
you need.

Fine media results in more impacts per
second over a given area. Therefore,
fine media is preferred for easy blasting
jobs, such as the removal of light rust
from steel.
Large media results in fewer impacts,
but each impact has more force, so that
large media is more suitable for difficult
jobs, such as removal of mill scale.

Page 13

Sometimes large and find media may be
combined for optimum results.
The chart below lists the range of media
recommended for each Pro-Finish®

R – Recommended. * Recommended optional vibrating screen for mesh sizes 200 to 300 or when high humidity is a problem.
NR – Not Recommended. ** Recommended optional vibrating screen and aerated media regulator for mesh sizes 200 to 300.

Spherical media, such as glass beads,
are used for general purpose cleaning
and finishing where a satin-like finish
is desired with little dimensional
change. Glass beads are effective when
used with pressures in the 20 to 60 PSI
range. Above 60 PSI, excessive bead
breakdown will occur.
Angular aggressive media, such as
aluminum oxide, steel grit, and garnet
generally provide faster cleaning and
produce a less-polished finish
compared to glass beads. Aluminum
oxide and steel grit are suitable for use
at pressures up to 100 PSI. Garnet

breaks down quickly at pressures
greater than 40 PSI.
Walnut shells or plastic are sometimes
used for delicate parts, paint removal,
or when a polished finish is required.
Pressures from 20 to 100 PSI may be
used with these media, depending on
the application.
When changing from one type of media
to another, clean the cabinet interior
and media hoses thoroughly to avoid
cross contamination.

CAUTION
If your application requires aggressive media, such as aluminum oxide, garnet, or
steel grit, it is recommended that you use optional heavy duty ducting,
reclaimer lining, and DI-CARB or BORON nozzles to prevent premature wear.
Empire strongly recommends using boron carbide nozzles when blasting with
Aluminum oxide, which is the most abrasive media.
If these options are not included with your system, they can be added. Optional
Rubber curtains for interior cabinet surfaces are also available. Consult your
Empire distributor for details.

IMPORTANT
Be careful not to overfill pressure systems. Overfilling will cause malfunction
and premature wear. See Subsection 4.1 Daily Maintenance.

3.3 Pneumatic Controls
The Pro-Finish® system uses a patented
pneumatic control circuit to protect
workers, workers environment, and
activate the blast.
Step 1: Turning the system ON/OFF
Switch to ON, energizes the interlock
Solenoid valve, permits air to enter the
control air line to the foot treadle,
illuminates cabinet lights and start the
fan motor.
Step 2: The operator steps on the foot
treadle opening a three way control air
valve. Air enters the door interlock
supply tubing continuing to the door
air jets. If the part load/unload doors
are closed, latched, and door air jets
are sealed, the control air lines
pressurize and open the main blast air
valve (and the pressure systems
exhaust valve to close). The opening of
the main air valve starts the blast.

Page 15

Step 3: When the operator removes his
foot from the foot treadle, the three way
air valve close, shutting off air to the
controls, and exhausting all down
stream air. The control air line
pressure bleeds from the door interlock
supply tubing, main blast air valve (and
the pressure system exhaust valve).
This permits the main blast air valve to
close (and the pressure system exhaust
valve to open) stopping the blast.
Step 4: When a part load/unload door
is opened, the pad covering the door
interlock air jet is unseated. When the
foot treadle is pressed with a door open,
control air bleeds from the door air jet
opening, preventing the control circuit
from pressurizing. The main blast air
valve will not open, and blasting will
not occur.

The following schematic diagrams illustrate the pneumatic control circuits for suction
systems (Figure 12A) and pressure systems (Figures 12B). For each system type, the
cabinets are shown in blasting and non-blasting modes (shaded pipe is pressurized).

3.4 Equipment Start-up
Step 1: After checking that all pipe and
hose connections are tightly fastened,
turn on the plant compressed air and
open the (user furnished) manual (ball)
valve(s) controlling air flow to the
system.
Step 2: Turn the cabinet power switch
ON.

Step 5: Set the blast air pressure
regulator at the desired pressure.
Recommended operating pressure
ranges for various media are listed in
the table below. Do not exceed 125 PSI
blast pressure.
Step 6: Grip the suction gun or
pressure nozzle assembly firmly and
step on the foot treadle. After a few
seconds the abrasive flow will stabilize
and you will be ready for blasting.

Step 3: Place parts to be blast-treated
in the cabinet. The parts must be free
of oil, grease, and moisture.

Glass Beads
Aluminum Oxide
Steel shot or grit
Walnut shells or plastic

Step 4: Close the cabinet door(s).

Suction Blast
30-60 PSI
30-100 PSI
80-100 PSI
20-100 PSI

Step 7: Hold the gun or nozzle at a
distance that produces the fastest
action. This distance may vary from 3
to 18 inches, depending on the work
piece and the desired finish. Avoid
pumping the foot treadle, as this will
decrease your efficiency and cause
premature wear of components.

Pressure Blast
20-60 PSI
20-80 PSI
20-80 PSI
20-80 PSI

The size of the effective blasting pattern
varies with the type and length of the
nozzle, air pressure, and the nature of
the work piece. Use the following chart
and diagram as a guide, but be aware
that the approximate pattern diameters
can only be determined by considering
each case individually.

3.6 Equipment Adjustments
Ventilation Flow Reclaimer Adjustment (for systems with reclaimers):
All Pro-Finish® reclaimers can be
adjusted to control the average size of
media retained by the reclaimer. The
reclaimer is supplied with a “tune-able”
secondary air adjustment. When the
band is properly adjusted reusable
media will be returned to the media
storage hopper. Unwanted dust and
broken down media (fines) will be
removed from the system and conveyed
to the dust collector. See Figure 5

HELPFUL HINT
Place a reference pencil mark on
reclaimer body (and a corresponding
reference mark on the tuning band if
horizontal slots).

Empire’s reclaimer design has vertical
slots with a solid tuning band. The
original Pro-Finish® reclaimers have
horizontal slots in both the reclaimer
and tuning band.

Step 4: Inspect the dust collector waste
drum for reusable media.

Fine tuning adjustments of both
reclaimers are similar. Just remember
to move the band in the direction of the
reclaimer slots; horizontal slots rotate
the band, vertical slots slide band up or
down.
The tuning band is joined at both ends
by a bolt and wing nut that must be
loosened before the band can be
adjusted. The slot pattern around the
reclaimer body has one slot omitted.
The joined ends of the tuning band
must be located over the area of the
omitted slot.

Step 2: Operate the blast system for at
least one hour.
Step 3: Turn the cabinet power switch
OFF.

Step 5: If no media is found in the
waste, adjust the tuning band to expose
1/16” more reclaimer body slot area.
Step 6: Make a new reference mark on
the reclaimer body.
Step 7: Repeat Steps 2 through 7 until a

small amount of media is found in the dust
collector waste. Adjustment is complete.
NOTE
As a new system is used, the filters
become coated with dust, “seasoned”
and the airflow in the recovery
system will decease to the normal
operating rate. This will affect
previous reclaimer tuning band
adjustments.

NOTE
Dust collectors require a coating of
dust on the filter cartridges to
achieve maximum filter efficiency,
also known as “seasoning”. The
filters are seasoned when the static
pressure reading on the collector
gauge is 2 or greater.

If visibility becomes poor inside the
cabinet when blasting, there is too
much dust mixed with the blast media.
The reclaimer tuning band should be
re-adjusted. Follow Step 2 though 7.
NOTE
For systems with large quantities of
dust mixed with blast media, all dust
and media should be removed from
the system and new media installed.

Step 1: Start with no reclaimer slots
visible. Adjust the band in one
direction until 1/16” of opening is
created between the band and
reclaimer slots.

Page 20

Step 8: If more than a small amount of
media is found in the dust collector
waste, additional reclaimer tuning band
adjustment may be required. Follow
Steps 9 through 13.
Step 9: Adjust the tuning band back to
the previous reference mark on the
reclaimer body, reducing the opening
between the reclaimer and the band.

Step 11: If no media is found in the
waste, adjust the tuning band to expose
1/16” less reclaimer body slot area.
Step 12: Make a new reference mark
on the reclaimer body.
Step 13: Repeat Steps 8 through 13
until a small amount of media is found
in the dust collector waste. Adjustment
is complete.

Step 10: After operating the blast
system for at least one (1) hour, turn
the cabinet power switch OFF. Inspect
the dust drum waste for reusable
media.
The schematic diagrams in Figure 13 illustrate:
(1) the basic operation of the system.
(2) the air and media flow before and after blasting.

Figure 13. Operating Principles

Empire Abrasive Equipment Company

IMPORTANT
An insufficient volume of secondary air entering the reclaimer will cause dust to
accumulate with the “good” media in the storage hopper or pressure vessel.
This accumulation leads to inefficient blasting. Conversely, too much secondary
air will cause useful media to be carried to the dust collector and be wasted.
To avoid these conditions, adjust the tuning band to meet your specific blasting
requirements. When your system is new, it will be necessary to readjust the
tuning band periodically until the filters are “seasoned”.
WARNINGS
Explosive Dust: Explosive dust is generated from blast media, removed coatings
and substrates. An extreme concentration of dust may combust if ignited by
spark or flame. As a precaution, clean the system and empty the dust collector
often. Change media that has excessive dust concentration.
Emptying the Dust Collector: Always wear an appropriate dust mask when
emptying the dust collector and changing filters. Empty the dust collector daily.
Ventilation Flow Adjustment Systems Without Reclaimers:
For these systems, ventilation air is
drawn directly from the cabinet. The
slide gate on the cabinet ventilation
outlet should be adjusted to give the
maximum flow of ventilation air without
carrying good media from the cabinet.

The proper adjustment of the gate can
be found through trial and error. Fine
media cannot be used in systems of
this type without having some of it
carried over to the dust collector or bag.

NOTE
If your media requirements change, you can easily add a reclaimer to your ProFinish® system.
Media Flow (Suction Systems):
Pro-Finish® suction blast systems are
equipped with the SAR-2 media
regulator to control the flow of media to
the Suction Blast Gun. The regulator is
located at the bottom of the Storage
Hopper assembly.
The amount of media entering the hose
is controlled by how far the media hose
is inserted into the regulator. For
normal operation, approximately ½ of
the air inlet port is blocked by the
media hose. This may vary slightly

Page 22

when changing media size nozzle size,
and/or blast pressure.
To find a uniform media flow, loosen
the thumbscrew and slide the media
hose into the SAR-2 regulator to
increase and withdraw the hose to
decrease media flow at the nozzle. To
determine if media is flowing, look
through the media regulator air inlet
while the gun is operating. Listen for
the sound of the blast to be smooth and
constant.

Empire Abrasive Equipment Company

Media Flow (Pressure Systems):
Pro-Finish® pressure cabinets are
supplied with the patented Sure-Flo®
grit valve. Adjust the media flow
through this valve by turning the Thandle. Start with the valve fully
closed by turning the T-handle
clockwise until you notice resistance.

clockwise until you notice resistance.
Then turn the T-handle counterclockwise in 1/4 turn or 1/8 turn
increments until you observe the
desired flow.

3.7 Helpful Hints for More Efficient Blasting
The efficiency of your blasting operation
depends on four factors:
1)
2)
3)
4)

Equipment selection
Media selection
Operating procedures
Maintenance

With the help of your Empire
Distributor and/or Empire factory
representative, you now own equipment
that will properly meet your blasting
requirements.
You can select the proper media,
operating procedures, and maintenance
steps by following the recommendations
in this manual. If you need more
information about any aspect of your
machine’s operation or the blasting
process, contact your local distributor
or the factory.
The following measures will also help
you improve the efficiency of your
blasting operation:
Step 1: To accomplish more in less
time, use the largest nozzle practical for
your operation. Of course, nozzle
diameter may be limited by the amount
of compressed air available, but an

Page 23

increased volume of compressed air is
often justified by reduced labor costs.
Also, if you are blasting small parts, it
doesn’t make sense to use a big nozzle,
as most of the blast pattern will be
overspray.
Step 2: For faster cleaning, use the
highest pressure practical for your
operation. Maximum pressure for a
given operation is limited by type of
media (e.g. glass beads can break down
rapidly above a certain pressure) and
amount of material which must be
removed from the workpiece.
Step 3: If you are blasting small parts,
it may be more efficient to manipulate
the part with tow hands and use an
optional fixed nozzle holder.
Step 4: Never underestimate the
importance of clean, dry air. More
operational problems are traceable to
the lack of clean dry air than any other
single factor. If the supply air is not
clean and dry, media quickly becomes
contaminated, causing flow problems,
which wastes media and leads to
excessive operator downtime.

Empire Abrasive Equipment Company

4.0 Maintenance
4.1 Daily Maintenance
Step 1: Check the condition of the media.
If the media is contaminated or broken
down into dust, thoroughly clean the
inside of the cabinet and recovery system
and reload with new media.
Step 2: Adjust the reclaimer tuning band
if you observe a dusty condition. See
section 3.6 Equipment Adjustments.
Step 3: Clean the filter bag or shake the
dust collector bags after every 2-4 hours
of operation.
A. For a single dust bag, remove the
bottom bag clip and shake the
accumulated dust through the bag
bottom into an appropriate
container.
B. For systems equipped with a
(baghouse) dust collectors, turn off
the cabinet power switch and
remove the dust from the bags by
pressing the bag-shake button 15
to 20 times.
C. Cartridge collector (CDC), empty
the dust drum when 2/3 full.
Dispose of the waste properly.
Step 4: Check light bulbs and gloves

Page 24

Step 5: Remove debris from the
reclaimer screen.
Step 6: Open the manual drain on the
general-purpose filter in the cabinet
pipe string and drain any accumulated
moisture and oil. Close the drain.
Step 7: Check the media level. For
optimal operation, the media level
should not drop below one-half the
recommended capacity.
A. The media level in suction can
be observed in the media storage
hopper.
C. The media level in pressure
systems can be observed by
looking through the sight glasses
or the reclaimer door down into
the top of the vessel. When the
vessel is de-pressurized, the
sealing plunger must be visible.
Add media until just visible at
the sealing plunger.
Step 8: All quick coupling connections
must be equipped with safety pins.
Inspect all couplings and blast hoses
daily for splits, bubbles, soft spots, etc.
Screws should be flush with coupling
surfaces. Tighten screws, if necessary.

Empire Abrasive Equipment Company

The following drawings show media flow through a typical pressure system and are
provided to help you understand how to maintain the media at the proper level.
Pictured at right is a fully charged system
with the vessel depressurized (no
blasting). Note that the media fills the
pressure vessel but that there is not
media in the storage hopper.

Before Blasting
When blasting starts, the vessel
pressurizes, the media impacts the part
being blasted, and reusable media is
recovered and accumulates in the
storage hopper. Continuous blasting
time is limited by the type and amount
of abrasive in the in the vessel when
blasting starts (normally 8 to 15
minutes with a fully charged 1 cubic
foot vessel, depending on nozzle size
and blast air pressure). Each time the
operator stops blasting, the vessel depressurizes and the sealing plunger
drops. Media in the storage hopper
flows into the vessel. If blasting is
stopped long enough (usually 1-2
minutes), all media in the storage

Page 25

hopper will transfer into the pressure
vessel.

During Blasting

Empire Abrasive Equipment Company

Thus, you can determine the amount of
media in the vessel in either of two
ways: (1) note how much continuous
blast time you can achieve with a fully
charged vessel and compare this with
your current continuous blast time; or
(2) stop blasting, open the reclaimer
door, and visually determine the media
level by looking into the top of the
vessel.

After Blasting
Overfilling pressure vessels will cause
improper operation and premature
wear. Allow sufficient time after
blasting for the pressure vessel to refill
(2 minutes). When the pressure vessel
is filled, check to see if any media has
remained in the storage hopper,
indicating that the vessel is overfilled,
the sealing plunger may not seat tightly
when you start blasting.
See Section 4.3 Storage or Temporary
Non-Use for instructions on how to
empty the pressure vessel.
Refer to Section 3.2 Media Loading for
instructions to add media.

Pressure Vessel Overfilled

4.2 Weekly Maintenance
Step 1: Repeat the daily maintenance
procedures.

Step 6: If the air jet shows wear, rotate
it 90° and reinsert it into the gun.

Step 2: Inspect all media-carrying
hoses for wear by feeling along the
length of the hose for soft spots. Hoses
with soft spots should be replaced.

Step 7: Re-tighten the set screw.

Step 3: Check the nozzle for wear.
When the nozzle is worn 1/8” oversize,
replace it. A drill bit can be inserted
into the nozzle to check its size.

IMPORTANT
If an air jet is allowed to wear
completely through, it will cause
premature wear of the gun body and
nozzle.
Step 8: Check the nozzle adapter and
gun body for wear. Replace if
necessary.

Step 4: On suction systems, check the
air jet for wear.
Step 5: Loosen the set screw in the side
of the gun body and remove the air jet.
See Figure 14.

Figure 14. Air Jet

Page 27

Step 9: Check the window gaskets for
leaks. Replace if necessary.
Step 10: Check your spare parts
inventory. Ensure that you have an
adequate supply of replacement items.

Empire Abrasive Equipment Company

4.3 Storage or Temporary Non-Use
If your Pro-Finish® system will not be
used for several days (or more), follow
these steps to remove media and
prevent media from caking inside the
system:

Remove the blast nozzle and washer
from the blast hose.

Step 1:

These steps will cause the media to flow
from the open end of the blast hose in a
controlled manner. The media can now
be directed into a suitable container or
receptacle.

•

C) Pressurize the vessel as if to
blast.

Suction systems:

Empty media from the cabinet and
storage hopper. To remove the media
from the storage hopper: remove the
rubber plug from the bottom of the
SAR-2 regulator.
•

After the pressure vessel is empty:

For pressure systems:
A) Reduce blast pressure to 40 PSI.

D) Open the choke valve.
E) Replace the nozzle washer and
nozzle.
F) Return the blast pressure setting
to normal.
Step 2: Drain the general purpose
filter. Close the drain valve.

B) Close the choke (ball) valve on
the pressure vessel pipe string.

5.2 Troubleshooting the Pneumatic Control Circuit
Hand Tools Required:

Step-by-Step Procedures:

The following tools are required to
troubleshoot the pneumatic control
circuit:

Refer to the control circuit schematics
shown in Figure 7 and the
troubleshooting procedures listed on
the pages following the figures.

•
•
•

Pressure tester (P/N 140382)
7/16” open end wrench
Flat-blade screwdriver

Figure 11. Pneumatic Circuit - Suction

Figure 12. Pneumatic Circuit - Pressure

Page 32

Empire Abrasive Equipment Company

Problem: Lights and blower work, but blast will not activate.
Step 1: Verify that the main air supply
is on and that the cabinet is receiving
air blast and regulator is set at proper
pressure. Check for obvious control air
leaks:
•
•

Are the doors tightly closed?
Are the door air jet seals in good
condition?

With the main switch ON and foot
treadle pressed, listen for air leaks.
Repair any air leaks that you find.

Step 3: With the power switch ON, step
on and off the foot treadle several
times. You should hear a slight hiss of
air at the foot treadle when you release
it.
If you hear the hiss, the blast, problem
is being caused either by:
•
•

a tubing leak, or
a faulty main air valve or
pressure system exhaust valve

If you do not hear an air hiss, the
absence of the blast is being caused by
one of the following:

Step 2: Turn the cabinet switch ON
and OFF.
If you hear a slight air hiss when the
switch is turned OFF, proceed to Step3.
If you do not hear an air hiss, the
absence of the blast could be the result
of either of the following (Refer to Figure
11 or Figure 12, as appropriate for your
system):
A. There is a leak between A and
the foot treadle valve C. Check
for leaks in the tubing between A
and the interlock solenoid B.

A. The foot treadle tab does not fully
press the foot treadle valve. To
verify this condition, remove the
treadle by taking out the bolt at
each end.
With the cabinet switch ON,
manually press the foot treadle
valve plunger.
If the blast is activated, you can
correct the problem by adjusting
the foot treadle tab, as follows:
•

Disconnect electrical power to
the cabinet.

•

Remove the Empire nameplate to
verify that tubing ends are firmly
connected.
Check for air leaks between B
and C.
B. The interlock solenoid B is faulty.
If no air leaks are found using
the procedure outlined in Step
2A, replace the interlock
solenoid.

Page 33

Loosen the two screws on
top of the foot treadle.
Slide the tab forward so
that it fully contacts the
foot treadle plunger.

B. The foot treadle is faulty. To
assess the condition of the foot
treadle, remove the air line D
downstream of the foot treadle.
If no air escapes when the foot
treadle valve is manually
pressed, the valve is faulty and
should be replaced.

Empire Abrasive Equipment Company

C. There is an air leak downstream
from the foot treadle valve. If
neither Step 3A nor Step 3B
reactivate the blast, disconnect
the tubing at D and connect a
test gauge to the tubing.

Step 4: To repair a leak in the tubing
downstream from the foot treadle, proceed
as follows:
Connect a pressure test gauge to the
tubing at E.
With the switch ON, press the foot treadle.

Manually press the foot treadle
valve.
If the gauge does NOT read full line
pressure when the foot treadle is
pressed, either the tubing upstream
of the door interlock or the foot
treadle valve is faulty and must be
repaired or replaced.
If the gauge reads full line pressure
when the foot treadle valve is
pressed, the problem is a leak
downstream from (in either the door
interlock D or control tubing).
Step 4 describes the procedure to correct a
line leak.

If the test gauge indicates full pressure
when the foot treadle is pressed, but the
blast is not activated, the main air valve is
faulty and must be replaced.
If the test gauge does not indicate full
pressure, the problem is being caused by a
leak between D and E at the door interlock.
Check the tubing for leaks. For pressure
systems, perform Step 5, as necessary.
Step 5: (Pressure systems only) To
determine if the exhaust valve or the
exhaust valve control line (E to F) is
leaking, proceed as follows:
If the control tubing between E and F is
intact and has no leaks, connect the test
gauge to the tubing at F.
If the blast activates when the foot treadle
is pressed, the problem is a leaking
exhaust valve or a ruptured diaphragm in
the exhaust valve. Repair or replace the
exhaust valve.

Page 34

Empire Abrasive Equipment Company

Problem: Excessive delay between stepping on the foot treadle and blast
activation.
(This delay should be between ½ and 1 second for suction systems and 1 to 2 seconds
for pressure systems.)
Remove the tubing at E and connect a test
gauge to the tubing.
With the cabinet switch ON, press the foot
treadle.
If the gauge pressurizes slowly to full line
pressure, the problem is restricted flow.
This condition could be caused by either A
or B below:
A. The foot treadle tab does not fully
press the foot treadle valve plunger.
To verify this condition, remove the
treadle by taking out the bolt at
each end.

B. The control air line is kinked or
crimped. Check the condition of the
control air lines.
If the test gauge pressurizes to a
pressure significantly lower than
full line pressure, there is a leak
in the control circuit. Proceed as
follows:
Trace leaks by moving the test
gauge upstream until full
pressure is observed. Check D
and E.
Full pressure at D indicates
leaking door interlocks.

With the cabinet switch ON,
manually press the foot treadle
valve plunger.

Low pressure at D indicates a
leak between:

If the blast activates in normal time,
you can correct the problem by
adjusting the foot treadle tab as
follows:
•

Loosen the two screws on top of
the foot treadle.

•

Slide the tab forward so that it
fully contacts the foot treadle
plunger.

Page 35

D and C, or
C and B, or
B and A.
On pressure systems only:
•

If the test gauge at F
pressurizes rapidly to full line
pressure, the exhaust valve
has a leak or a ruptured
diaphragm.

Description
Voltage/Frequency/Phase of power available.

Available with Manual, turntables facilitate the handling of heavy
parts. The turntable dolly travels on a track, or is fixed inside the
cabinet. Most stationary designs feature a low profile that provides
operators with easy “over-the-top” access and does not waste
interior cabinet space. Turntable size 24” diameter with standard
capacities ranging from 300 to 1000 pounds.
Pressure blast systems incorporating Empire’s automatic Sure-Flo
media regulator, allow the operator to adjust the richness of the
air-to-media mixture from the workstation at the front of the
cabinet. As a result, dialing in the optimum air-to-media ratio for
a particular job is greatly simplified. To further assist the operator,
an indicator gauge displays relative media richness.
In applications where media is changed frequently, or where
contamination can cause periodic clogging of the media regulator,
a push-button choke is available with fine tuning.
In applications such as shot peening, in which very precise
metering of media is required, a fixed-orifice media regulator is
attached below the Sure-Flo media regulator.
The low media-level sensor and indicator warns the operator when
the media supply in the pressure vessel is low. The
indicator/sensor consists of an electronic probe in the vessel that
activates a signal light mounted on the front of the cabinet.
Empire’s extended wear components increase service life in an
aggressive or high-use environment. These components are
normally very cost-effective because they reduce downtime, repair
interval, and maintenance costs. Extended wear components are
sold individually so you can tailor features to your application
needs and budget
An easily replaceable inlet wear plate protects the most vulnerable
area of the reclaimer.
The urethane coating extends the service life of interior wear
surfaces by five times.
The Ultra-Wear lining increases normal service life by a factor of
ten.
Di-Carb nozzles are for use with steel abrasives and glass beads.
Boron carbide nozzles are for use with aluminum oxide, silicon
carbide, and garnet media.
Cabinet life is increased with the use of rubber curtains. Freehanging curtains are made of black 1/8” neoprene and held in
place with rubber knobs for easy replacement. These curtains
actually last longer than steel. White curtains are available to
brighten the cabinet interior, and it doesn’t degrade with use, as
does white paint on steel.
Window protectors can be provided in clear plastic or as a
perforated screen to reduce frosting and pitting of the cabinet
window.
To pad parts and prolong the life of steel support surfaces, mats
are offered for turntable tops and cabinet floors.
Suction blast systems
The fixed gun holder is adjustable to position any gun in any
orientation so the operator can use both hands to manipulate work
pieces in the blast stream.

Description
The fixed nozzle holder, which bolts anywhere on the cabinet wall,
can be adjusted to position the nozzle in any orientation, leaving
both of the operator’s hands free to manipulate work pieces.
A vibrating screen in the reclaimer (plus an aerated media
regulator for pressure systems) overcome flow problems associated
with very find abrasives (200 to 300 mesh range), lightweight blast
media (plastics, walnut shells, etc.), and high humidity.
Magnetic reclaim separator reduces possible damage to delicate
substrates by removing steel and other ferrous contaminants from
the blast media as it passes through the reclaimer. The separator
consists of an industrial magnet that can be removed through the
reclaimer door for cleaning.
Automatically pulse the filters as required.
