Absolute filters | BWF Envirotec

The classification of clean rooms and other controlled work environments is specified in demanding technical standards. Therefore the filters used there must meet the highest standards of performance and effectiveness.

Filter made from pleated materials is called minipleat. Depending on the type, it can be separated by an aluminium foil separator or cotton threads separator, or glue. Filter medium is placed in an MDF frame (wooden board), made from aluminium or galvanised sheet. Normally, from the front of the frame an elastic polyurethane seal is placed.
