This flat bank ASHRAE air filter housing is designed to accommodate a variety of ASHRAE-rated air filters with different efficiencies and configurations. It is available in both 8-1/2" deep single-stage and 12" deep multi-stage designs.

The single-stage housing can accommodate either 2" or 4" standard filters, while the multi-stage version can hold two filter stages using standard 2" and 4" filters.

Using the included flange, the housing can be installed in space-restricted locations such as inside ductwork or adjacent to air handling units. Upstream corner gussets provide added structural rigidity.

Flat bank housings are available with a wide range of options, allowing customization to meet specific application requirements.
