Pentair Pentek PBH Series Bag Filter Housings keep your system on stream longer by reducing bag filter change time. Molded from rugged reinforced polypropylene, this PBH-410-1 bag vessel is lightweight and corrosion-resistant, giving you the strength you need without the weight. This 10-inch, 1" NPT housing holds a standard 4" x 8.25" filter bag that reduces sediment and particulate. Bags are available in polypropylene felt, absolute-rated high-efficiency polypropylene, and nylon monofilament mesh for filtering and straining from 1 to 800 microns. The single large ACME thread closure ensures quick opening and positive sealing, and the vessel comes complete with a lead-free gauge, wrench, and 3/8" drain valve. Ideal for residential pre-filtration, food service, and commercial and industrial water and chemical filtration, the PBH-410-1 is rated to 100 psi maximum and 40 to 100 degrees F. Filter bags are sold separately; guard against freezing to avoid cracking and water leakage.
