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 hygienecompliant 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 f Ta f +80 °C.

Product details

  • PRODUCT DETAILS
Recommended final differential pressure - service life of filters


Depending on the operating mode and system design, the optimum service life should be as long as possible with energy-efficient low pressure differences and safe hygiene. We recommend that the filter change be carried out according to the following sequence when criteria are met:


1. Defective filter


2. Hygienic reasons


3. Reaching the recommended final differential pressure
3.1 Filter group COARSE
The lower value from:
  • Addition of 50 Pa to the differential pressure for unpolluted filters
  • Triple the value of the differential pressure for unpolluted filters


3.2 Filter group ePM
The lower value from:
  • Addition of 100 Pa to the differential pressure for unpolluted filters
  • Triple the value of the differential pressure for unpolluted filters


4. Economic optimisation of the system


5. Temporary limit
5.1 First filter stage after one year at the latest
5.2 Second filter stage after 2 years at the latest
5.3 Final filter (HEPA filter) no later than 8 years after the date of installation


6. Reaching the maximum permissible final differential pressure depending on the filter used
