MFPCR

* 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.

Specification text
Mini Pleat filter panels MFPCR for the separation of suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in clean room systems with controlled air cleanliness and airflow. Use as particulate filters, i.e. main or final filters, for the most critical requirements of air cleanliness and sterility in areas such as production, research, medicine, pharmaceuticals industry, and nuclear engineering. Mini Pleat filter panels for clean room technology, consisting of an extruded aluminium frame, filter media of high-quality, moisture-resistant glass fibre papers with spacers made of thermoplastic hot-melt adhesive. Variable pleat depths enable optimal adjustment to individual requirements. Cleanroom technology available in standard and special sizes, filter groups ISO ePM10, ISO ePM2.5, ISO ePM1 (fine dust filter) and EPA, HEPA, ULPA (particulate filter). As standard, mini pleat filter panels for cleanroom technology are equipped with a continuous seal or fluid seal on the upstream side, depending on the version. Optional designs are available with a seal on the downstream side, on both sides, or with protection grid (arrangement as needed), and with full-surface laminar fleece or laminar fleece strips. Mini pleat filter panels for cleanroom technology are tested as standard from filter class H14 using the automatic scan test.

• Optimal pleat geometry of the filter medium
• Low-turbulence outflow of clean air
• Leakage test using the scan test as proof of leak-tightness and as assurance for compliance with separation efficiency and pressure loss
  
  

• Filter media made of high-quality, wet-strength glass fibre papers, pleated
• Spacers made of thermoplastic hot-melt adhesive provide a uniform spacing of the pleats
• Joint sealing compound made of permanently elastic two-component polyurethane adhesive
• Frame made from extruded aluminium section
