“OFF” position and bleed the air when closed. Close the main air shutoff valve. Make the
compressed air connection to the Blast Cabinet pipe string on the back wall of the Cabinet.
The supply line must be at least as large as the pipe string inlet. If the supply line must be run
more than 25 feet, increase the line to one size larger.
2.9 DUST COLLECTOR COMPRESSED AIR SUPPLY
2.9.1 Cartridge Dust Collectors with Reverse Pulse
Connect a 1” airline to the Dust Collector manifold. Plug the opposite end of the
manifold. A 90-100 PSI air supply is required for proper operation of the cleaning
pulse. If line pressure exceeds 100 PSI, a regulator must be installed in the Dust
Collector air supply.
NOTE: IF AIR PRESSURE EXCEEDS 100 PSI, THE DUST COLLECTOR
CARTRIDGES WILL BE SEVERELY DAMAGED.
2.10 A qualified electrician may now make the necessary electrical connections in accordance with
applicable codes. Refer to the Electrical Drawings. If not provided with your system, an
Electrical Disconnect shall be provided to open all ungrounded supply conductors. This
disconnect shall be located within sight of the Main Electrical Enclosure.
2.10.1 Complete the wiring from the Dust Collector and other electrical components to the
Main Electrical Enclosure. Once these connections are complete, the Blower Motor
should be jogged and the rotation checked. Fan blades must rotate toward the fan
outlet. If the rotation is incorrect, open the Main Electrical Disconnect and switch two
of the three-phase Motor power connections to reverse the motor direction.
2.10.2 The Blast Cabinet and Reclaimer stand must have a good earth ground. The Urethane
Duct static ground wire must be connected to the earth ground.
2.11 Shut off all manual air valves on the system.
2.12 Open the main air supply valve. Check each manual air valve, all control lines and the entire
system for leaks.
2.13 Before proceeding, check that all gearboxes are filled with oil to the correct level. Refer to
the gearbox manufacturer’s instructions. Generally, the oil level should be just above the
centerline of the input shaft.
2.14 Prior to adding media, review the function and operation of system components as described
in Sections 3.0, 4.0 and 5.0. Also check for and remove from the interior of the Blast Cabinet
cone and Storage Hopper debris (metal shavings, nuts, bolts, etc.) that may plug media
orifices and Blast Guns.
SUGGESTION: Use a magnet on a long handle or shop vacuum to clean debris from the
bottom of the Blast Cabinet cone and Storage Hopper.

3.0 FUNCTION OF COMPONENTS
This section gives a brief description and explains the operation of system components.
3.1 OPERATOR ELECTRIC CONTROL PANEL
3.1.1 The red illuminated “EMERGENCY STOP” operator disengages the “Emergency
Stop Relay” and removes power from all motion devices and their respective controls.
When activated, the operator illuminates indicating its active state. Resetting of the
operator is performed by twisting and pulling.
3.1.2 The green “SYSTEM ON” illuminated pushbutton is used to energize the system and
turn on the Dust Collection System. The pushbutton Illuminates to indicate its “ON”
status.
3.1.3 The red extended head “SYSTEM OFF” pushbutton is used to shut off the system and
Dust Collection System. Pressing this operator extinguished the lamp in the
“SYSTEM ON” illuminated pushbutton.
3.1.4 Cabinet “LIGHTS”. This selector switch turns on the cabinet lights when put in the
“ON” position.
3.1.5 The white “BLAST” “OFF” or “ON” selector switch sets the system to allow blasting
with media. This initiates the door locks and activates the blast solenoid when required
by the process. This selector switch illuminates when in the “ON” position.
3.1.6 The “SYSTEM” “MANUAL” or “AUTO” selector switch allows for manual
operation or automatic operation which would be initiated when pressing the cycle
start pushbutton. Manual operation is used for setup and maintenance purposes.
3.1.7 The green “CYCLE START” pushbutton enables the Blast Cycle. This pushbutton
will illuminate when the system is in a Blast Cycle. If the system is placed in a hold
status, the indicating lamp will flash.
3.1.8 The red extended head “CYCLE STOP” pushbutton pauses the blast and nozzle
movement during a Blast Cycle. This allows any modifications to the part position or
media flow to be made and the process then resumed.
3.1.9 The amber “HOPPER LOW” indicating lamp illuminates when the media level in the
storage hopper falls below the capacitive level sensor.
3.1.10 The red “SYSTEM FAULT” indicating lamp illuminats in the event of a system fault.
Details on the exact fault can be found utilizing the Operator Interface Terminal
(OIT).
The lamp extinguished when the fault is cleared and the system reset.
3.1.11 The black “FAULT RESET” pushbutton is used to reset the system fault and return
the machine back to normal running conditions.

Page 8
SPCL36104-S Suction System
3.1.12 The blue “E-STOP RESET” illuminated pushbutton is used to enable the Emergency
Stop Relay (ESR) and apply power to all motion control components. This operator
illuminates when the circuit is energized and in a normal operating mode.
3.1.13 The “BLAST ELAPSED TIME INDICATOR” records the total time that nozzles are
blasting. The “BLAST” selector switch must be in the “ON” position for this
hourmeter to run.
3.1.14 the white “TRY” illuminated pushbutton is to be used to verify the presence or lack of
power when the main disconnect is turned off and locked out for service.
3.1.15 (remote) an additional “EMERGENCY STOP” pushbutton station is located near the
loading door of the machine. Pressing this will disengage the ESR and remove power
from all motion devices and their respective controllers. This operator will illuminate
when pressed and remain lit until power is removed or the operator is reset.
3.1.16 (remote) A green Tower Light is used to alert the operator to the run condition of the
process cycle. A steady green light indicates that the current cycle is in process. A
blinking green light indicates that the system is in a hold state. When the light is
extinguished, either the cycle is complete or the system is waiting for the next cycle to
be run.

SPCL36104-S Suction System
3.2 OPERATOR LOAD & UNLOAD STATIONS
The operator opens the load door and slides the part over mandrel. When finished, operater
removes the part.
3.3 BLAST PRESSURE CONTROL
3.3.1 Locate the Pressure Regulator on the pipe string on the media storage hopper. Rotate
the Pressure Regulator knob clockwise to increase, or counter clockwise to decrease
the Blast Pressure.
3.3.2 Precision Regulator
An optional Precision Pressure Regulator pilot and slave regulator provides more
accurate control of Blast Pressure when blasting parameters are critical. Pressure is
adjusted manually at the pilot regulator, clockwise to increase and counter clockwise
to decrease the Blast Pressure.
3.3.3 (N/A) Optional Front Access Pressure Regulator
This option allows the operator to monitor and/or change the Blast Pressure from the
front of the Blast Cabinet. The operator does not have to walk to the back of the
machine to adjust the pressure.
3.4 BLAST COMPONENTS
The MH-2 Suction Blast Gun and MH-3 Suction Blast Gun mix blast air and media. They
exit from the nozzle creating the blast. The air leaving the air jet entering the nozzle cone
creates suction, pulling media and air through the media hose from the Media Regulator. See
Figures 1 and 2.
3.4.1 Nozzle
The Suction Blast Gun is designed to accept nozzles made of boron carbide, tungsten
carbide or ceramic. Boron carbide is the longest wearing nozzle material and is
strongly recommended when blasting with aluminum oxide or silicon carbide medias.
Standard sizes are 1/4”, 5/16”, 3/8” and 7/16” ID. A nozzle adapter is threaded onto
the Gun Assembly to hold the nozzle in place.
Boron carbide is the hardest and longest wearing nozzle material. It is strongly
recommended for use when blasting with aluminum oxide or silicon carbide medias.
A 3/8” boron Venturi nozzle is available for the MH-3 suction gun.
3.4.2 Air Jet
The air jet is located inside the Suction Blast Gun and is threaded into the air inlet
connector. It discharges the blast air to the rear of the nozzle. The air jet is hardened
steel for extended wear.

Page 10
SPCL36104-S Suction System
3.4.3 Air Jet Connector
The MH-3 air connector is fastened to the gun body by two socket head screws. Air
jet position is fixed within the gun and is not adjustable.
3.4.4 Media Hose
3.4.4.1 (N/A) The 5/8” media hose enters through the handle of the MH-2 gun. A
hose clamp nut and “O” ring seal the hose to the gunbody. Any air leak around
the media hose will cause premature wear and failure of air jet and gunbody.
See Figure 1.
3.4.4.2 The 5/8” media hose enters the MH-3 Suction Blast Gun at the back and is
held in place by four (4) screws. The gun hose entry must be sealed with
silicone. Any air leak around the media hose will cause premature wear and
gun body failure. See Figure 2.
NOTE:
Blast hoses must be routed with a sweeping gradual bend. Tight turns and hard bends
cause high wear locations where the hoses will prematurely wear out from the inside.
When replacing hoses, avoid sharp bends and turns.
3.4.5 Media Regulator Assembly (See Figure 3)
The SAR-2 Media Regulator is threaded onto a 1 1/4” pipe nipple under the Storage
Hopper. The media hose is inserted into the 1 1/8” horizontal bore of the regulator.
The thumbscrew is provided to apply slight pressure against the media hose to prevent
movement. The media hose will partly cover the secondary air port. A smaller
opening will increase media flow and a larger opening will decrease media flow.
3.4.6 Storage Hopper
The Storage Hopper has a four (4) cubic foot capacity and is used as a reservoir for
media. It should be one half (1/2) full or more at all times. There is a hinged access
door for loading media and trash screen removal.
3.4.7 Individual Suction Blast Gun Shutoff Valves
A ball valve is provided to shut off each Blast Gun. Rotate the valve handle 90
degrees to shut off the air supply and stop the blast.

Page 11
SPCL36104-S Suction System
3.5 PNEUMATIC RECLAIM SYSTEM
The Reclaim System consists of a pickup tube at the bottom of the Blast Cabinet cone, a
media recovery duct, and a Reclaimer Assembly. The Blast Cabinet ventilation air is used to
pneumatically convey spent media to the Reclaimer. Good media is centrifugally separated
from dust and broken down media (fines). Good media falls to the Storage Hopper while dust
and fines are conveyed to the Dust Collector. The Reclaimer has a secondary air metering
band and exterior wear plate. Optional wear resistant linings are available for the Reclaimer.
3.5.1 Secondary Air Metering Band (See Figure 4)
The metering band allows secondary air to enter the Reclaimer. The more secondary
air induced, the larger the particles removed from the system and sent to the Dust
Collector. If good media is carried to the Dust Collector, close the metering band. If
too much dust is being recycled along with the good blast media, open the metering
band. Changes should be made in 1/16” increments until the final setting is
determined. A system must normally be operated for (8) hours to “season” the filters
before it reaches equilibrium and the tuning band setting may be finalized. See the
appropriate section in Chapter 9.
3.6 DUST COLLECTION COMPONENTS
The Dust Collection System components consist of the Dust Collector with filters, the filter
cleaning controls, and the Blower. Dust and fines are drawn from the Reclaimer to the Dust
Collector. Clean air is discharged from the Blower. One of two types of Dust Collector may
be supplied and are described below. With any Dust Collector, filters require a coating of
dust to achieve maximum filter efficiency. The system may require several hours of operation
before filters are fully coated (“seasoned”).
3.6.1 (N/A) Bag Type Dust Collector
The Dust Collector must be shut down periodically to allow bags to be cleaned.
Tubular bags are mounted with the sealed end up and hooked onto a hanger rod on the
dust bag rack. The open end of the bag has a ring which seals into holes in the bag
plate in the hopper of the Dust Collector.
3.6.2 Filter Cleaning
Filter bags are suspended from the bag rack at the top of the Dust Collector housing.
The bag rack is lifted and lowered by a cylinder at a moderate rate, flexing the bags
and dislodging dust and fines. Filters should be cleaned every two (2) hours. This
may vary depending on dust loading. Manual cleaning is accomplished after the
Blower is shut down and the button on the side of the Dust Collector housing is
pressed and released.
3.6.3 (N/A) Optional Auto Bag Shake Control
The Auto Bag Shake Control Box, mounted on the Dust Collector, energizes and de-
energizes a solenoid valve to raise and lower the bag rack. A normally closed vacuum
switch enables the Bag Shake control only when the Blower is shut down. Auto Bag
Shake controls may be located in the Main Electrical Enclosure and not use a pressure

Page 12
SPCL36104-S Suction System
switch. A timer controls the duration of the shake cycle and a flasher controls the
cylinder movement by powering the solenoid valve.
3.6.4 Cartridge Dust Collector
These Dust Collectors can operate continuously without Blower shutdown.
Electronically timed pulses of compressed air clean the dust from the cartridges
without interfering with normal airflow. Refer to the manufacturer’s manual for
complete information.
3.6.5 Dust Collector Efficiency
Dust Collector efficiency may not be stated as an absolute value since it will vary
depending on:
a. Dust loading of inlet air
b. Micron size distribution of dust carried by inlet air
c. Amount of dust cake on filters (frequency of filter cleaning)
Emissions from Empire Dust Collectors in good condition will normally be within the
OSHA limit for “nuisance dust”. The OSHA limit is 5 milligrams of dust per cubic
meter of air (.002l85 grains per cubic foot). This emission rate is equal to .0042
pounds of dust per 1000 pounds of air at standard temperature and pressure. To
determine the actual emission rate, an air sample from the blast operation must be
analyzed.
Dust Collector efficiencies are stated to show the normal range which might be
expected and are not a guarantee of performance.
If dust contains any toxic substances, secondary filtration of discharge air from the
Blower may be required. Consult Empire if dust to be filtered is classified as other
than “nuisance dust”.

Page 13
SPCL36104-S Suction System
4.0 OPTIONAL COMPONENT FUNCTIONS
Additional options may be supplied with the system. The following are available at time of
manufacture.
4.1 POWERED PART HOLD DOWN ROLLERS
Pneumatic powered rollers hold the part down against the mandrel. The rollers come down on
each end of the part to secure it during a blast cycle. One set of these rollers moves
horizontally to accommodate the length of the part to be blasted This is accomplished thru the
PLC .
4.2 NOZZLE OSCILLATOR
The Nozzle Oscillator drive is mounted on the back wall of the Blast Cabinet. An oscillating
bar extends into the Blast Cabinet to support the Blast Guns. The Oscillator moves
horizontally over the surface of the part. Home (park) position may be extended or retracted
and is determined at time of manufacture.
4.2.1 (N/A) Pneumatic Cylinder Driven Oscillator
This Oscillator provides an inexpensive means of increasing blast coverage.
Oscillation speed is adjustable with flow control valves at each of the cylinder’s two
(2) ports. Limit switches control the cylinder stroke length. The duration of the blast
is controlled by a Blast Timer or a Blast Counter.
4.2.2 D.C. Motor Driven Timing Belt Oscillator
The D.C. driven Oscillator permits improved control of oscillation speed and distance.
This is required when precise blast specifications must be met. A DC Motor Control
Board controls the Oscillator Speed. Stroke length is controlled with the PLC.
4.2.3 D.C. Motor Oscillator with PLC Control
When incorporated with a PLC, the processor may be programmed to control the
Oscillator movement including Park Position, Blast Length and Blast Strokes/Time.
A DC Motor Control Board controls Oscillator Speed.
4.3 (N/A) AUTOMATIC MEDIA REPLENISHING SYSTEM
This system includes a 4 cubic foot capacity Makeup Hopper, an automatic Sure-Flo®Grit
Valve and a Makeup Hopper Low Level Sensor. The Sure-Flo®Grit Valve at the bottom of
the Makeup Hopper will open and add media to the system if the media level in the Storage
Hopper is not at the proper level. The Makeup Hopper Low Level Sensor and a panel
mounted indicating light which will illuminate when the Makeup Hopper must have media
added.
This option is particularly useful when media must remain consistent. As media breaks down
and is drawn to the Dust Collector, fresh media of the proper size will mix with the reclaimed
media ensuring a consistent mix and repeatable finish.

Page 14
SPCL36104-S Suction System
4.4 (N/A) VIBRATORY CLASSIFIER (SCREENER)
The purpose of a Vibratory Classifier is to have more control over the media that is reclaimed
from the blast process and put back into the Storage Hopper. When media “breaks down” as
a result of hitting the part being blasted, it may change shape (deform), and it may fracture,
resulting in smaller particles of media. Consequently, what is often found in the Storage
Hopper consists of a combination of properly sized media particles, undersized media
particles, virgin media from the Makeup Hopper, material that has been removed (e.g.
cleaning or surface-etching processes) from the part being blasted and possibly dust.
Contaminants such as dust and particles dislodged from the part being blasted are usually
carried over to the Dust Collector by the cyclonic Reclaimer, which is better than 90%
efficient. However, small amounts may wind up in the Storage Hopper. These contaminants
plus undersized media particles may reduce the efficiency of the blasting process. Blast
processes that require very precise control of the media often include a Vibratory Screener,
which is practically 100% efficient. A series of mesh “screens” located on successive “decks”
sequentially filter the material that is removed from the Blast Cabinet. Dust and undersized
media particles are removed and dumped into a waste drum and good reusable media is sent
to the Storage Hopper.
4.5 (N/A)FRONT ACCESS PRESSURE REGULATOR
This option allows the operator to monitor and/or change the Blast Pressure from the front of
the Blast Cabinet.

Page 15
SPCL36104-S Suction System
5.0 SYSTEM START-UP PROCEDURE

5.1 Open the main air valve.
5.2 Close the Main Electrical Disconnect switch and turn on the Blast Cabinet lights. Listen for
the Automatic Bag Shake control to operate if your system has a Bag Type Dust Collector.
NOTE: Reverse Pulse Cartridge Dust Collectors only clean while the Blower is in operation.
5.3 Perform Daily Maintenance and Operation Check. See Section 6.0.
5.4 The system is now ready for production.
5.5 Follow the Sequence of System Operation. See Section 7.0.

Page 16
SPCL36104-S Suction System
6.0 SYSTEM MAINTENANCE AND OPERATION CHECK
Follow all the steps in this section to insure the system is ready for production.
6.1 DAILY CHECKS
6.2 Dump the Dust Collector waste. Inspect the waste for good media. If large quantities of
usable media are present, refer to Section 9.7.
6.3 Inspect the contents of the Storage Hopper. It must be one half (1/2) full or more at all times.
Clean the trash screen. Check the size and condition of the media and look for large
quantities of dust and fines. If poor media quality and/or large quantities of dust and fines are
found, empty the Storage Hopper and install new media into the hopper. Refer to Section 9.7.
6.4 Inspect all supply and control airlines and hoses for wear or leaks. Repair or replace as
needed before operating the system.
6.5 Inspect the media hoses for leaks and wear. Interior wear of the media hose may be checked
by pinching the hose to detect soft spots. Bends in the media hose will wear before straight
sections. If a hose is worn, replace it before operating the system.
6.6 CABINET INTERIOR WEAR DUE TO BLAST
Special precautions have been taken to protect the interior of the Blast Cabinet from
premature wear. Due to the high volume of abrasive media being delivered by the Blast
Nozzles at a high pressure, wear is unavoidable. Careful daily maintenance and inspection
are mandatory to the longevity of this system.
6.6.1 Operators and maintenance personnel should familiarize themselves with the expected
high wear areas within the Blast Cabinet.
6.6.2 There will be a high wear area opposite each Blast Nozzle. If the system is blasting
without parts, the blast stream will impact upon the surface in front of the nozzles.
6.6.3 Inspect the Blast Cabinet interior for wear to the rubber curtains and metal surfaces.
Replace worn curtains promptly. They prevent wear to the sound absorbing material
(when supplied), Blast Cabinet walls and cone.
6.7 Clean debris from the Blast Cabinet screens and cone. Replace light bulbs and globes as
needed.
6.8 Inspect the rolling mandrel components for wear. Check the drive for loose and worn
components, and oil leaks.
6.9 Inspect the nozzles and couplings for external wear and holes in the sides of the assembly. If
holes are found, replace the worn components before operating the system.
6.10 (N/A) Inspect the top of the Blast Cabinet for loose components and gearbox oil leakage.
Repair the oil leaks and check oil levels before operating the system.

Page 17
SPCL36104-S Suction System
6.11 Inspect all Oscillator limit switch arms for free movement and all split collar limit switch
trippers for tightness and proper orientation. Repair and/or adjust before operating the
system.
6.12 Replace all cracked or frosted windows, worn window curtains, and damaged door gaskets.
6.13 Turn the “BLAST” selector switch to “OFF”. Press the “SYSTEM ON” pushbutton.
6.14 Observe the operation of the rotating mandrel. Check that hoses do not rub on the interior of
the Blast Cabinet.
6.15 Turn the “BLAST” selector switch to “ON”. Observe blast from each nozzle. Pay special
attention to media flow, direction, and consistency of flow. Correct any problem before
operating the system. Refer to Section 9.0.
6.16 Press the red “SYSTEM OFF” pushbutton to shut the system down. On Bag Type Collectors,
listen for the Dust Collector Automatic Bag Shake to operate. If the Bag Shake does not
function, repair it before operating the system. Cartridge Dust Collectors Reverse Pulse clean
only when the system is “ON”.
6.17 PERIODIC CHECKS - (N/A)
6.18 MANDREL REPLACEMENT
If the Mandrel needs replacement due to different part diameters, locate the coupling that
secures the mandrel to the main drive shaft. Before loosening this coupling properly support
the mandrel through out its length then diassemble it. When installing a new mandrel be sure
to add the rubber washer that is located in between the end of the drive shaft and the matching
end of the mandrel. This washer creates the necessary seal required when appling air for the
I.D. blowoff.

“PART LENGTH” for the next cycle. Pressing in
the orange field or the corresponding soft-touch function
key will bring up a numeric entry panel. Here the
desired value is entered.
If the length of the part to be run is shorter then the
previously run part, the “PINCH OSCILLATOR”
will have automatically repositioned itself. In the
event that the new part to be run is Longer than the previous part, the oscillator will need to be
reset by either pressing the “F7” button or the “reset” button on the screen.
Once the parameters are correct and the oscillator is in the correct position, the operator then
needs to acknowledge that the Part Setup is Complete by pressing the “YES” button or “F8”.
Movement from this screen to other screens is done by pressing the desired button on the
screen or their corresponding function key.
The current Cycle Status is also displayed on this SETUP SCREEN.
7.11.4 PROCESS MONITOR
This screen displays the current setup parameters
and the process variables at the current point in the
operation cycle.
The current “CYCLE STATUS” is also shown on
this display.
Movment between screens is again performed by
touching the desired button of pressing the desired
function key.
7.11.5 MAINTENANCE SCREEN

Page 20
SPCL36104-S Suction System
Pressing the “MAINTENANCE” button or “F4” on the main screen brings up the
“MAINTENANCE” menu screen. From here a choice of “ADDITIONAL SETUP
PARAMETERS”, OSCILLATOR JOG SCREEN” , or “CYCLE TROUBLE SCREEN” can
be made.
In the event that communication problems arise or the operator interface program acts
irratically, the “GO TO CONFIG SCREEN” button can be pressed.
This switches to the panelview operations setup screen where the program can be restarted
and/or setup changes made.
Again, movement between screens is performed with the touch screen or the function keys.
7.11.6 ADDITIONAL SETUP PARAMETERS
This screen allows the setting of four additional
process control variables. These variables are to be
used for fine tuning of the process and are not meant
to be continually adjusted.
“PART SURFACE SPEED” is used to set the speed
at which the part will rotate. Adjusting this setting
will speed up or slow down the mandrel rotation and
thus the surface speed the part is processed at.
“MANDREL BLOWOFF” turns ON or OFF the
flow of air thru the mandrel and into the ID of the
part.
“OSCILLATOR REFERENCE SPEED” sets the reference value used to calculate the
horizontal travel speed of the BLAST OSCILLATOR during a cycle. This is also the speed
that the largest diameter part would be run at. The actual Oscillator speed is the ratio of the
largest part diameter / the current part diameter multiplied by this reference value.
“BLOWOFF SPEED” is the travel speed of the BLAST OSCILLATOR during its
BLOWOFF stroke , return to home.
7.11.7 OSCILLATOR JOG SCREEN
This screen is used to manually position the
oscillators for assisting in setup of the guns and or
Maintenance of components. The mode of operation
must be in the MANUAL mode in order to activate
any of these motions. The Pinch Oscillator will not
move unless the cyclinders are in the UP position.
Homing of the Blast Oscillator will move the gun
assembly automatically back to their HOME
position and should be performed any time the
BLAST OSCILLATOR is jogged or the cycle is
aborted during running. This resets all required counters to allow proper operation in future
cycles.
7.11.8 CYCLE TROUBLE SCREEN
In the event that a cycle will not start, this screen
will give a possible indication as to the reason why.
All indicators should be in their “GREEN” satisfied
state in order to perform a cycle. The Media Status
