HEPA/ULPA Housings
Side Access HEPA Filter Housings are designed to accept all gasket-type HEPA filters. They are all-welded factory-assembled flanged units suitable for installation in a duct on the downstream side of an air handling unit. Housings guarantee filter system efficiency equal to the efficiency of the individual filters. Optional prefilter tracks are designed to accommodate 2in. pleated panel filters with efficiency ranges up to 50% per ASHRAE Standard 52.1 dust-spot test methods. Both prefilters and primary HEPA filters are serviceable through gasketed access doors.
