2.4 Installing the Compressed Air Supply
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

* Standard nozzle
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”).
Line Size (in) Length of Air Line (ft) Air Volume (SCFM)
¾ Up to 95 13 to 38
1 95 to 190 38 to 59
1-1/4 190 to 350 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
Blast System. Certain media, such as sand and slag, are not to be used in Pro-

cabinets, both for health
reasons and because they pulverize on impact and cannot be recirculated.

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
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.
at pressures up to 100 PSI. Garnet
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.

3.3 Pneumatic Controls
The Pro-Finish 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.
®
system uses a patented
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.

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 3: Place parts to be blast-treated in the cabinet. The parts must be free of oil, grease, and moisture.
Suction Blast Pressure Blast
Glass Beads 30-60 PSI 20-60 PSI Aluminum Oxide 30-100 PSI 20-80 PSI Steel shot or grit 80-100 PSI 20-80 PSI Walnut shells or plastic 20-100 PSI 20-80 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.
Step 4: Close the cabinet door(s).
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.
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.
