Dryfast G4 coarse filter for filter box

G4 coarse filter - pre-filter for coarse particles

The g4 coarse filter for the Dryfast FB300 filter box is an important pre-filter for capturing coarse particles. The filter captures initial contamination and is usually combined with an f7, f9 or hepa filter to extend the life of the finer filters. The g4 filter removes larger particles above 10 microns, such as coarse dust, sand, leaves, insects and hair, with a low pressure drop. The filter is cost-effective and easy to replace.
