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.
The chamber cover has large handles with large buttress threads enabling removal and re-installation of the chamber cover manually without tools; the chamber cover o-ring (available in EPDM or FPM) is a captured design so it does not fall out during chamber cover removal. A vent valve is provided to evacuate air during initial filling. The cover itself is designed to displace air to keep venting to a minimum and to make it safer to access the filter bag chamber if it has not been drained.
The base of Hayward PVC and CPVC bag filters has a flat and thick molded bolt holes to secure the housing to grade. Ergonomically these bag filter housings are a very well thought-out design which should endure many years of harsh service.

Request Pricing Order Filter Bags Call 908.362.9981Hayward PVC and CPVC FLV housings accept industry standard #1 bags (7" diameter x 16" long) and #2 bags (7" diameter x 32" long). The bag determines micron rating and efficiency.
They are rated up to 100 GPM at 150 PSIG. Actual flow may be limited by pipe size or the filter bag selected.
PVC is the standard choice for many water and chemical services. CPVC is selected when higher temperature capability or a different chemical compatibility profile is required. End connection material matches the body material.
True-union socket, threaded and flanged connections from 1¼" through 4" depending on bag size. True-union ends support high-side, low-side or same-side outlet layouts. A lower port can be used as a drain or second outlet.
No. Large cover handles and buttress threads allow hand removal. The captured EPDM or FPM cover o-ring stays in place. A cover vent valve is included for fill and drain.
