 AIR-300 OVERVIEW
 SPECIAL FEATURE 
The Alpha® Air Polisher was designed with human engineering for operator comfort.  
It comes equipped with a silencer which reduces the level of noise as well as 
guiding the cold exhaust air away from an operator during the polishing process.  
This feature also eliminates excess lubricant dripping on the work piece.  Portions 
of the body design are made with synthetic materials and covered with rubber to 
prevent fatigue and coldness to hands.

system should include a regulator and a moisture trap.
