ALPHA AIR-830 Pneumatic Polisher 

The Best Polisher just became Better! The Alpha® Air polisher set a standard as the pneumatic polisher with a center water feed many years ago and changed how stone fabricators polish the edges of hard surfaces. Since then competitors have copied the design in various ways just emphasizing the high Alpha® standard. Introducing the latest Alpha®: the AIR-850 Pneumatic Polishers that will make the polishing operation easier than ever. The polisher comes with new splash guard which blocks the splash while providing better visibility. The end case was also re-designed to improve the water and air control operation and minimize the risk of breakage. In addition, we added a silicon boot for the gear head, and water quick coupler with shut off valve, for your comfort and convenience. The Alpha® polisher always come with an enhanced spindle shaft and full size wrenches for easy tool removal. The all-weather air and water hoses are 15ft. and rated for -40°F or +140°F. The AIR-830 has a maximum no-load RPM of 4,000 and the AIR-850 has 5,500.
