Patent-pending Sealing System Prevents Filter Bypass
SAAF Air Purification Systems are uniquely designed to hold and securely seal SAAF Cassettes. AAF’s patent-pending SAAF Seal High Integrity Sealing System prevents bypass of unfiltered air. Cassettes and filters are locked in place by a combination of cassette notches and cassette Iocator bars. Designed to maintain optimal positioning of the cassettes, the Iocator bar ompresses the cassette into the sealing gasket. This unique system is completely effective and ensures exceptional filter efficiency.
Clean Contaminated Air From Within or Without
SAAF Air Purification Systems are designed to support SAAF chemical media cassette filters, prefilters and after-filters, and high efficiency particulate filters in one self-contained stand-alone unit. The units are designed for optimal removal of gaseous contaminants and airborne particulate from intake and recirculated ventilation air.

Prefilters and After-filters
AmAir® filters are ideal prefilters used to prevent the buildup of lint and dust on the face of the SAAF cassettes and high efficiency filters.

High Efficiency Final Filters
Both the SAAFzRU and SAAF:PRUwiII accommodate a high efficiency final filter bank to ensure that filtered air meets the highest levels of efficiency. VariCel® M-Pak extended surface pleated filters (MERV 14, 13, and 11) are the perfect choice for high efficiency particulate removal. VariCel M-Pak filters boast a compact 6″ – deep filter design while maintaining the same media area and performance as 12″-deep filters.
