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.
European Association of Air Handling and
Refrigerating Equipment Manufacturers,
Eurovent’s certification tells our clients that
Ulpatek fine filters are tested by
independent research laboratory and that
Ulpatek's published product information
must be accurate. Ulpatek has also ISO
9001 to ensure quality operations since the
day production started.
