Alpha AIR Series Pneumatic Polishers

The Alpha AIR Series Pneumatic Polishers are high-performance air-powered polishing tools designed for professional stone fabrication, wet polishing, profiling, grinding, and core drilling applications. Built upon Alpha's industry-leading center water-feed technology, these polishers deliver consistent water flow regardless of tool position, helping to improve polishing performance, reduce dust, and extend pad life. Equipped with a newly developed motor featuring advanced hybrid vane technology, the AIR Series produces greater power, improved efficiency, and longer service life than previous generations.

Designed for maximum operator comfort and productivity, the AIR Series features a lightweight ergonomic body, redesigned splash guard for improved visibility, silicon gear head cover for added comfort, and all-weather air and water hoses that remain flexible in extreme temperatures. Available in both standard-speed and high-speed configurations with either 5/8"-11 or M14-2 spindle threads, these polishers provide the versatility required for a wide range of fabrication applications.
