IB 200 Prefilter (G4)

This filter has a very high dust holding capacity, recommended to use as a first stage filter and/or as prefilter in air ventilation systems. This is an in-depth filter catching dust particles from the air on its full surface. In order to make fitting easier two sides of the filter, where the air enters are marked with blue. Can be washed and partially regenerated, but cleaning is not recommended as it decreases the filter’s efficiency.
