AIR ABRASIVE SUPPLY REQUIREMENTS
Abrasive blasting requires a large volume of air at high pressure. The efficiency
of your abrasive blaster can be adversely affected by the use of too small an air
supply hose, insufficient air pressure or an overly large nozzle.

We recommend that air pressure in the range of 65/110 PSI will provide the best
Results.
LOADING ABRASIVES INTO THE TANK
1. Check your abrasive to be sure it’s dry, and won’t clog the metering valve
(19B), abrasive outlet pipe (23), hose (25), or other components.
2. Put on the protective clothing, full hood and MSHA/NICOSH approved
Respirator.
3. Turn the air supply valve (19) to the off (horizontal) position.
4. Push down to open the nozzle DEADMAN valve (34).
5. Watch the pressure gauge (16) and make sure it reads zero pressure.
6. Remove the filler cap (13) from the top of the tank.
7. Insert the funnel (31), and pour the abrasive into the funnel. Be sure to get
enough into the tank to do the job at hand. But if this is a big job, fill the
tank only 3/4 full, and reload as needed to finish the work.
TIP: if the humidity is 90/100%, the water trap (18) won’t be able to trap all of the
moisture in a 3/4 tank. Better to reduce the amount of abrasive, load more
frequently, and empty the water trap more open. This will reduce the possibility of
clogging the bottom of the tank or the line.
8. with the correct amount of abrasive in the tank, close the filler cap (13).
