Filter cassettes

EFC cassettes are equipped with an accordion-shaped filter media. The filter media is self-supporting and equipped with shape memory. It is made of cardboard or a thin layer of polyester fibres or fiberglass without the addition of a bonding agent.

Cassette frames are available in cardboard, polyester, galvanised or stainless steel, and can be inserted into the galvanized steel or stainless steel support frame. The accordion shape of the filter media substantially increases the filtration surface and thus, at an equal pressure, allows for the decrease in resistance.
