Efficiency acc. EN 1822:2009: H13
MPPS efficiency acc. EN 1822:2009: ≥99,97% at 0,3μm, ≥99,95% at MPPS, measured at 20ºC with DEHS
Recommended final pressure drop: 500 Pa
Temperature / Humidity: 350ºC / 100% RH Filter packed in plastic film. Due to the different thermal expansion coefficients of the individual filter components the ceramic potting may form cracks during the tempering process. At operating temperature (350ºC) these filters have an overall efficiency of 99,97% at 0,3μm, leackages are possible.
