The Side Access Polyseal housing utilizes a high density Nylon piled gasket which is automatically positioned against the final filter as it is installed into the mounting track. The “air actuated” seal prevents dirty air bypass while retaining its integrity over time. Vertical sealing between filters is provided by gasket strips applied to the sides of the final filters and to the housing doors.
Side Access PolySeal housing is offered in 96 sizes and 3 housing depths. It will accommodate both 2″ and 4″ prefilters and final filters used in combination or individually. When used with other AAF IAQ-engineered filter products, the Side Access PolySeal effectively removes particulate air contaminants from the air supply.
