MFP

Application

• Mini pleat filter panel type MFP for the separation of fine dust and suspended particles such as aerosols, toxic dusts, viruses, bacteria from the supply and extract air in ventilation and air-conditioning systems with large volume flow rates and long filter service lives.
  
  
• 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

Special characteristics

• Leakage test is standard for all particulate filters of classes H13, H14

Construction features

• Perimeter flat seal on the upstream side for constructions MDF, GAL, STA, ALN, ALZ and ALY
• Some constructions with optional foamed continuous seal or with a test groove seal (filter classes H13, H14) on the upstream side; the flat section or continuous seal can also be fitted on the downstream side or on both sides
• 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
