AIR FILTER TECHNOLOGY



       Coarse, Medium and Fine Filters






       Classification Standard EN779:2012
       The EN 779:2002 classification system (comprising groups F and G filters) has
       been changed to three groups (F-,M- and G-filters).
       Filters found to have an average efficiency value of less then 40 % of 0,4 μm
       particles will be allocated to group G and the efficiency reported as “< 40 %”. The
       classification of G filters (G1 - G4) is based on their average arrestance with the
       loading dust.
       Filters found to have an average efficiency value from 40 % to less than 80 % of
       0,4 μm particles will be allocated to group M (M5, M6) and the classification is
       based on their average efficiency (0,4 μm). The filter classes F5 and F6 have
       changed to M5 and M6, but with same requirements, as in the old classification
       system.

       Filters found to have an average efficiency of 80 % or more of 0,4 μm particles
       will be allocated to group F (F7-F9) and the classification is based on their average
       efficiency (0,4 μm) as in the old system and the minimum efficiency during the
       test.
