Fine dust filters manufactured by TROX are EUROVENT certified and tested in accordance with European Standard EN779, filter class F5 – F9.
All TROX filters fulfil the required criteria such as initial pressure drop and filter class which are tested and confirmed once a year by a neutral test institute.The complete TROX range of filters is produced in the Goch plant and, depending on the filter class, tested in accordance with EN779 or EN1822.
For both standards there are scan testing devices which are ISO9001 certified. The technical data of the coarse dust and fine dust filters are determined on the filter test bench according to EN779.
HEPA and ULPA filters are tested with the scan testing device (EN1822-4) for leakage limit (testing the local filtration efficiency) and the integral filtration efficiency.
