Air handling unit filter (AHU Filter)
Air handling unit filter V (vertical) washable extended surface filters are used as a pre-filter for ventilation systems designed with galvanized steel, aluminum and PVC frames.
V WASH Washable extended surface pre-filter G3/G4. The synthetic poly fiber filter material is arranged pleated in a zig-zag frame for low-pressure loss and to support high dust holding capacity. The media is made of high-density synthetic poly fiber and another feature is V wash filters are washable. For low impact applications, flat and replaceable material models are available. The filter efficiency class is ISO-16890- Coarse 65%. EN997- Efficiency Class: G3 (EU3) – G4 (EU4).
Available at standard size and nonstandard sizes can be produced upon request.
