The wire frame forming the filter frame is factory-sewn with filter media of the required filtration class. The clogged filter can be replaced with a new complete filter, including a metal frame, or more economically, by changing the filter medium. After removing the dirty filter medium, a spare filter sleeve is threaded on the wire frame, the end of which must be fixed after folding.
We supply replacement filter media (filter sleeves) up to a length of 10 m.
They are used in the window and ceiling units for air filtration with the value of separation in the classes of filtration G2, G3, G4.
