The AF 22 is the top seller among the standard extraction units and is available as a mobile or stationary model. With a footprint of only 51" x 23", the AF 22 is a true space-saver. Its vacuum power measures an exceptional 1,800 CFM, which means the AF 22 is unmatched in this price/performance class. The two chip bags can hold up to 106 gallons and are especially easy to change thanks to the chip double-bag system. As required, the AF 22 can be ordered configured a vacuum hose or vacuum pipe connection.
