Side Access Polyseal

Side Access Housings

Product Overview

The Side Access Polyseal filter housing is engineered for use with air handling units or other side access equipment. It offers the convenience of servicing the filter from outside the air duct and is especially suited for installations involving limited headroom. It is a general purpose filter housing that provides mechanical strength, ease of use and economy. It will accommodate both 2″ and 4″ prefilters and final filters used in combination or individually.

The Side Access Polyseal housing was specifically designed to meet IAQ air cleaning requirements when used with AAF high-efficiency filters treated with an antimicrobial. Many factors contribute to IAQ problems, but the primary contributors are particulate dust and microbial contamination in the air we breathe.
