Bag Housings
Bag filter housings are available in a wide range of configurations and materials. Bag filters are ideal for high flow filtration applications. They are often used for coarse filtration but they are capable of filtering down to 1 micron. A size #2 bag is the standard size for high flow, multi round housings. There are several parameters that must be taken into account but as a guideline, a single #2 bag housing is typically good for flow rates of 100 GPM.
How Bag Filtration Works
Bag filter housings use a perforated mesh basket to support the filter bag. Unfiltered liquid enters above the bag, filling the housing, then flows through the bag from the inside out. Particles are trapped while filtered liquid exits. O-rings ensure a secure seal between the lid, basket, and housing. Multi-bag systems operate similarly. Systems are designed for a clean differential pressure of ~1 PSID, with filter bag replacement recommended at 15-20 PSID.
