Air filter HT series

panelindustrialfor clean rooms

The filter frame is made from anodized extruded aluminium profile with two angles in each corner to get a rigid straight frame. The zinc coated hood with an attached collar is tie glued on top of the housing. At the damper (version A) the aerosol / pressure drop checking inlet is placed in a special middle bridge and is adjustable from downstream. The fibreglass media, which is pleated in ‘Minipleat-shape,’ is available in three different heights (47, 56 and 70 mm) and is cast into the filter frame and middle bridge. This design gives a highly active filter surface and ensures the minimal pressure drop of the HT model. Testing Each filter is tested and packed in accordance with American Standard IEST-RP-CC-001.3 (HEPA and ULPA Filters) or in accordance with the European standard EN 1822-1, 4&5 (testing filter elements HEPA and ULPA efficiency and scan method) or customer requested testing.
