Inlet Blower Filters (MF)

Advanced Filtration Technology

Freudenberg Filtration Technologies manufacture Inlet Blower Filters commonly known in the market as “MF” filters (deriving from MicroFresh) for General Mining and Industrial Process Air applications.

Inlet Filter Elements are produced primarily for blowers and compressors. Inlet Blower Filters (MF) are installed in such industries as mining, foundries, food manufacturing, waste treatment, plastic manufacturing, recycling, and many more.

The filters are designed using materials to suit industry and the operating environment. Changing safety standards and the need to improve performance means that new materials are being used in our manufacturing processes.

All intake silencers require an air filter element as an important part of the silencer.  

These elements should be selected so that the filtration is adequate to protect the tolerances of the blower and take into account the type and concentration of dust in the ambient air.

Filter cartridges should be selected for different efficiency requirements according to the following details.
