Specification text
Mini Pleat filter insert type MFI 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. Used as fine dust filters, prefilters or final filters in AHU units; or as particulate filters, main or final filters for highest requirements of air purity and sterility, in areas such as industry, research, medicine, pharmaceuticals, and nuclear technology. Low installation depth due to compact V-design, for systems with high volume flow rates and long filter service lives. Filter media made of high-quality, wet-strength glass fibre papers, with spacers. Optimum pleat position and largest possible filter area allow low initial differential pressures. Mini Pleat filter inserts available in market sizes, filter groups ISO ePM10, ISO ePM1 (fine dust filters) and EPA, HEPA (particulate filters). As a fine dust filter (filter groups according to ISO 16890) as standard without seal, optionally available with flat seal, as a particulate filter, Mini Pleat filter inserts are equipped with a flat seal. Filter classes E11, H13 and H14 as standard with protection grid on the downstream side. Mini Pleat filter insert as fine dust filters are certified according to Eurovent. Mini Pleat filter inserts MFI are hygiene-compliant according to VDI 6022.
The filter insert MFI with optional EX protection MFI-EX may be used in areas with a potentially explosive atmosphere of zones 1 and 2 and zones 21 and 22 (EX II 2G Ex h IIC Gb and EX II 2D Ex h IIIB Db).
The filter must be connected to the ground potential. All conductive and dissipative parts must be connected to each other and to earthed. Conductive dusts are excluded from the application. Make sure that no metal particles can get into the filter. Ambient temperature range: -40 °C ≤ Ta ≤ +80 °C.
