The Alpha AIR-300/304 Pneumatic Polisher is a compact wet air polisher designed for polishing sink cutouts, bowls, edges, and other detailed stone surfaces. Its small profile allows access to areas where larger polishers cannot operate effectively.
The polisher features a central water-feed system that delivers water directly to the polishing surface and operates at a maximum no-load speed of 5,800 RPM. It accepts 3" and 4" polishing discs, 2" to 4" backing pads, and is available with either a 5/8"-11 spindle thread (AIR-300) or M14-2 spindle thread (AIR-304).
