" AAF " 560-595-003 AMERICAN AIR FILTER

Designed to meet the stringent requirements of HEPA filter applications, AstroSeal^® Type S housings are engineered to perform reliably, even in the toughest environments. The AstroSeal^® Type S was specifically developed to perform as efficiently as your HEPA filters. The innovative design ensures uniform and constant pressure against the sealing surface of the HEPA filter. Type S housings are available with prefilter tracks to meet the exacting specifications of HEPA filtration.

AstroSeal^® Type S housings are available with a 2" or 4" wide prefilter track. Blank off panels are provided to prevent prefilter bypass. Prefilters are accessed through the final filter access door. Factory pressure testing of the housing and filter sealing surfaces guarantees complete HEPA filtration integrity. Available in a wide range of efficiencies, cell side materials and separator designs, AAF manufactures and tests AstroCel^® filters to fit Type S housings.
