From the paper mills on the West coast, to textile mills on the East coast, and to the hospitals and airports in the Midwest, Permatron’s commercial air filters are the original industrial workhorses of permanent, washable electrostatic air filtration, proven effective for over 60 years. Model HFA is one of the best and the oldest washable electrostatic air filters available today, ideal for facilities that require a high particle arrestance efficiency like a hospital, laboratory or nursing home.
Our exclusive Accumulator Chamber® construction features a unitized filter bank design. Multiple sets of steel framed media is assembled with distinct separation to create a triple action filtration system. This prefilter/afterfilter assembly promotes free air flow with superior dust holding capacity while resisting face loading. Excess particulates sweep through the prefilter and cross currents within the chamber cause further agglomeration and settlement until the filter is rinsed clean. No system modifications or electrical hook-ups are needed.
