2 Inch Thick High Efficiency Commercial Electrostatic Air Filter

Permatron model HFA 2" thick frame is on of the best commercial washable electrostatic air filter available. Features a combination of woven electrostatic polypropylene, nonwoven polyester and wire reinforcement encased within a galvanized steel frame. Ideal for hospitals, laboratories, and nursing homes that require excellent particle arrestance efficiency.

A unitized filter bank design is featured in Permatron's distinctive Accumulator Chamber® construction. To develop a triple action filtering system, multiple sets of steel framed media are combined with distinct separation. While resisting face loading, this prefilter/afterfilter assembly supports unrestricted air flow with outstanding dust holding capacity. Excess particles pass through the prefilter, causing agglomeration and settling until the filter is washed clean. There are no system upgrades or electrical connections required.
