Introducing the latest Alpha® Pneumatic Polishing Solution! Alpha® AIR-680UW is a Pneumatic Polisher for use underwater for polishing and grinding. This tool is a modified version of our best-selling AIR-680 which now has a 27ft vacuum hose to allow underwater polishing on most pool sizes. This high performance, pneumatic polishing tool has a central water-fed distribution system that produces the highest quality finishes. It has a maximum speed of 4,000 RPM, consumes 15 CFM and requires 85 PSI. With a 5/8”-11 spindle, the AIR-680UW is lightweight and ergonomically designed. It is now equipped with 15ft flexible air and water supply hoses and a 30ft air hose as well as oil port for easy maintenance. These new hoses are made of Hybrid Flexible Material and are all-weather flexible down to -40F. The versatile tool can also be used without the vacuum hose for wet polishing.
