EFKC filtered shelter fans are used to supply fresh air. It can be used in two different positions thanks to the by-pass cell. Normally, the air is sent indoors only by passing through the G4 Filter. When we want the air to be cleaned, it is passed through the G4 cassette filter, active carbon cassette filter and M6 cassette filter, which is more sensitive than the coarse filter, and sent indoors. By-pass air dams are made with a sliding system.
