    (China)YY378 -Dolomite Dust Clogging

    The product is applicable to EN149 test standard: respiratory protective device-filtered anti-particle semi-mask; Conforming standards: BS EN149:2001+A1:2009 Respiratory protective device-filtered anti-particle semi-mask requirements test mark 8.10 blocking test, EN143 7.13 and other test standards.

     

    Blocking test principle: the filter and mask blocking tester is used to test the amount of dust collected on the filter, the respiratory resistance of the test sample and the filter penetration (permeability) when the air flow passes through the filter by suction in a certain dust environment and reaches a certain respiratory resistance.
