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.
FilterSource can help you select the right system based on your specific needs. We offer a wide range of filter bag housings in stock that are available for immediate shipment. Current inventory includes single bag housings all the way up to 12 round bag housings. Housings can also be custom built to your precise needs.

Bag filter housings have an internal perforated mesh basket that provides support for the filter media (bag). Unfiltered liquid enters the housing above the filter bag and liquid fills the interior of the housing. Liquid flows thru the filter bag from the inside out. Particles are trapped while the processed liquid moves out of the filtration system. O-Rings are used to create a positive seal between the lid, basket and housing. Multi bag systems function the same way. Systems are typically designed with a clean differential pressure of around 1 PSID. It is recommend to change out the filter bag when the system reaches a differential pressure of 15-20 PSID.
