General Information
Application
- Mini Pleat filter cell type for the separation of fine dust and suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in ventilation systems with large volume flow rates and the requirement for long filter life
- Fine dust filter: Prefilter or final filter for the separation of fine dust in ventilation and air conditioning systems.
- Particulate filter: Main or final filter used for the most critical requirements of air cleanliness and sterility in areas such as production, research, medicine, pharmaceuticals industry, and nuclear engineering

- Spacers provide a uniform spacing of the pleats
- Sealing compound made of permanently elastic two-component polyurethane adhesive
- Frame optionally made of stainless steel
Standards and guidelines
- Tested according to ISO 16890; International standard for general ventilation and air conditioning; classification of separation efficiency based on the measured fractional separation efficiency, which is processed into a reporting system for the fine dust separation efficiency (ePM)
- For fine dust filters, the fractional separation efficiency of a certain size range is determined by aerosols (DEHS and KCl)
- Depending on the test values, the filters are classified into filter groups ISO ePM10 and ISO ePM1
- Testing of particulate filters to EN 1822-1 and ISO 29463-2 up to ISO 29463-5 (EPA, HEPA and ULPA filters): Standards for testing of filtration performance in the factory, based on particle counting method using a liquid test aerosol
- Uniform classification of particulate filters according to separation efficiency, using a test aerosol with an average particle size within the minimum separation efficiency (MPPS)
- Particulate filters are classified into the filter groups EPA (filter classes E10, E11, E12), HEPA (filter classes H13, H14) and ULPA (filter classes U15, U16, U17), according to the values determined for local separation efficiency and integral separation efficiency.
- Hygiene conformity in accordance with VDI 6022, VDI 3803, DIN 1946 Part 4, ÖNORM H 6020, SWKI VA 104-01 and WKI 99-3 as well as EN 16798
