Hayward PVC and CPVC Bag Filter Housings For use with standard #2 size filter bags

Hayward PVC and CPVC bag filter housings are compatible with industry standard #1 (7″ diameter x 16″ long) and #2 (7″ diameter x 32″ long) filter bags. The filter bags themselves determine the particle retention and filtration efficiency. Generally speaking Hayward PVC and CPVC bag filters are used for 1 to 200 micron nominal filtration applications. “Nominal” is a reference to the initial efficiency of the filter bag material; as the filter bag becomes clogged its efficiency increases as the pathways for fluid narrow or become increasingly complex. Most manufacturers use filter bag material that is at least 65% efficient and perhaps as high as 75% for their nominal rated filter bags. Absolute rated filter bags are also available, although the seal interface between the filter bag and Hayward bag filter is not supportive of absolute filtration <25 microns.

Inside each bag filter housing are a restrainer basket (supports the filter bag) and a sealing ring (transfers the chamber cover force across the circumference of the filter bag seal). Hayward bag filter vessels are ergonomically designed to be installed and maintained without the need of tools. The true union connections enable flexibility for a high or low side outlet and even same side outlet. An additional lower port can be used as a drain or as an additional outlet port.
