AIR-300
Introducing the Alpha® AIR-300, designed for unique applications that are difficult to
accomplish using conventional polishers. A smaller version of the well-known
Alpha® AIR-658, the AIR-300 is ergonomically designed to fit comfortably in your
hand and only weighs 1.6 pounds reducing fatigue from long hours of polishing. The
smaller design is easy to maneuver and produces flawless sink rims and bowls. The
Alpha® AIR-300 accepts 3" and 4" discs along with 2", 3" and 4" rubber pads. It
requires a 3HP compressor with air consumption of 10 CFM and air pressure
between 85–95 PSI. The Alpha® AIR-300 Polisher easily converts from in-shop to
on-site; a must have for all fabricators!
