Construction features

• As standard, constructions ALU/ALV are fitted with a fluid seal
• Protection grid made of expanded metal, can be fitted on the downstream or upstream side or both sides as required

Materials and surfaces

• Filter media made of high-quality, wet-strength glass fibre papers, pleated
• Spacers provide a uniform spacing of the pleats
• Sealing compound made of permanently elastic two-component polyurethane adhesive
• Frame made of either plastic, MDF, galvanised sheet steel, stainless steel, or extruded aluminium sections

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 according to EN 1822-1 and ISO 29463-2 to ISO 29463-5 (EPA, HEPA and ULPA particulate filters): Standards for testing the filtration performance in the factory, based on particle counting methods 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.

• Hygienic conformity for versions ALN, ALZ, ALY, ALU, ALV: VDI 6022, VDI 3803, DIN 1946 Part 4, ÖNORM H 6020, SWKI VA 104-01 and SWKI 99-3 as well as EN 16798
