Web1 feb. 2016 · The efficiency of this medium is class E11 (EN-1822). This medium makes it possible to easily observe the two filtration phases on the pressure drop change curves, i.e. depth filtration and filtration on the surface. The packing density of this medium is approximately 0.06 and the average thickness is 480 μm. WebThe primary factor in filter replacement is pressure drop. Typically, HEPA filters are replaced when the pressure drop exceeds 100 mm WG. By specification, HEPA filters must have sufficient structural pressure to withstand a continuously applied overpressure of 250 mm WG or higher for at least 15 minutes without visible damage or loss of ...
