Description
Application
- Mini Pleat filter panel for the separation of suspended particles such as aerosols, toxic dusts, viruses, bacteria from the supply and extract air in cleanroom facilities with controlled air cleanliness and airflow.

Standards and guidelines
- Testing of particulate filters according to DIN EN 1822-1 and DIN EN ISO 29463-2 – DIN EN ISO 29463-5 (EPA, EPA, and ULPA particulate filters): Standards for testing filtration performance at the manufacturing plant, based on particle counting methods using a liquid test aerosol.
- Testing in accordance with DIN EN ISO 16890; international standard: air filters for general ventilation. Classification of fractional efficiency based on the measured fractional efficiency which is processed into a reporting system for the particulate matter efficiency (ePM)
- For fine dust filters, the fractional efficiency of a certain size range is determined by aerosols (DEHS and KCl)
- Depending on the test values, the filters are classified into the filter groups ISO ePM10 and ISO ePM1
- 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, according to the values determined for the local separation efficiency and the overall separation efficiency, into EPA (filter classes E10, E11, E12), HEPA (filter classes H13, H14) or ULPA (filter classes U15, U16, U17)
- Hygiene compliance: VDI 6022, VDI 3803, DIN 1946 Part 4, ÖNORM H 6021 and ÖNORM H 6020, SWKI VA 104-01 and SWKI 99-3, and EN 16798
Technical information
* With a pleat depth of 20 mm, the upstream velocity is 0.45 m/s.
Depending on the filter class and the pleat depth, the initial pressure differential [Pa] is determined.
The nominal volume flow is the product of the associated upstream velocity and upstream face area of the filter (B × H), minus the profile thickness. See chapter Quick sizing.
