DV Series Filter Material

1. Introduction of DV Series Filter Material

DV Series Filter Material is made of chemical fibers and manufactured by non-woven and high-temperature techniques. It is poison-free, odour-free, acid-proof and alkali-proof.

This series filter material is filled with different kinds of chemical fiber in different layers, which equips the material with the feather of high efficiency, small resistance and big dust holding.

This series filter with high strength can avoid deformation and fragment caused by stretching, curling, wind pressure, and dust retention, which increase its service life.

2.DV/G Series Primary Filtering Material Technical Data

This kind of filter material can be made into filter bag and applies to filter the dust which is bigger than 5μm.
