filtering half mask (ffp2 mask)-pg电子麻将胡了下载

ffp2 masks are tested under en 149:2001 a1:2009 standard and approved to the personal protective equipment (ppe) regulations. these masks are designed to help protect the wearer from exposure to airborne particles, and to offer high levels of particle filtration and to seal tightly to the wearer’s face therefore reducing the potential of air leaking into the wearer’s breathing zone from around the edges of the mask.

total inward leakage: ≤ 8

particulate filtration efficiency (%) ≥ 94%

breathing resistance (mbar): inh. 2.4 @95lpm, exh. 3.0 @160lpm
