Testing of particulate filters
EN 779: Particulate
air filters for general room
air-conditioning
This Norm is concerned with the performance testing of
particulate
air filters with an Efficiency against atmospheric
dust of up to 98% (see leaflet: F0/2/EN/.) The particulate
filters are divided into filter grades F5 to F9 according to
their test results to EN779.
Testing of high efficiency particulate filters
EN 1822: High efficiency particulate filters
(HEPA and ULPA)
This new European Norm testing procedure is based on
particle counting using a liquid test aerosol of varying
particle sizes.
The filters are rated by filter class according to extract
efficiency or penetration.
Leak test
Tests are carried out in accordance with an oil mist test
to EN 1822, a local scan test to verify the filters are free
from leaks.
TROX offers the following:
F781: Filter panels individually tested for leaks
0 = Standard with oil mist test
or at increased price:
E = Scan test (particle counting)
