MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as the air comes from the compressor pump. When humidity is high or
when a compressor is in continuous use for an extended period of time, moisture will collect in the tank. When using a
sandblast gun, this water will be carried from the tank through the hose and out of the gun as droplets mixed with the
material being sprayed.
IMPORTANT: THIS CONDENSATION WILL CAKE THE SAND AND CLOG THE SANDBLASTING GUN. A CLOGGED GUN WILL
NOT OPERATE.
A compressed air dryer and/or air line filter will help eliminate this moisture.
