Depth Filter Cartridges
With its gradient density depth construction, our depth filter cartridge products are an economical option for the removal of both fine and coarse deformable and non-deformable contaminants. Ideal for use as a prefilter, protecting costly downstream pleated cartridges/equipment, or as a final filter in a wide variety of industries and applications.
GWTB Series is a great replacement for the discontinued FSI Vorex (CMMF) filter cartridges.
