PolySeal ASHRAE Housing
PolySeal ASHRAE air filter housing
The Side Access ASHRAE Housing is designed to hold 2 stages of ASHRAE rated air filters. With multiple unit depths and filter tracks available, Side Access Housings can meet the specific requirements of many systems.

Units are available in 22-1/4”, 34-1/4”, and 42” depths and are constructed from either galvanized or stainless steel. Depending on the configuration, housings are bolted and/or intermittently welded together and seams are caulked with silicone to prevent air bypass. Additionally, the upstream corners are gusseted to increase rigidity.

Side Access Housings can be made utilizing a large number of options, meaning housings can be customized to meet a variety of different situations and requirements.
