When your next project requires bag filtration we encourage you to consider one of PEP’s pre-engineered systems.  Each filter is designed for quick and easy installation.  Just pipe it in and wire to a single point contact and you are ready to produce clean water or other filtered fluids.

Each PEP BGSF series filter removes suspended solids from water and other process liquids. Contaminants such as pipe scale, grit, wax, metal chips, rust, and airborne debris are found in a broad range of particle sizes. PEP offers a variety of bags to capture particles ranging from 5 to 800 microns.
