Pentair® Pentek® RFC Series Cartridges’ unique radial flow design offers the benefits of granular activated carbon (GAC) filtration, such as low pressure drop, while at the same time significantly reducing the release of carbon fines commonly associated with GAC-style cartridges. These filters are constructed with a 70-micron porous polyethylene outer shell and durable polypropylene end caps. The 2-3⁄4″ outer diameter cartridges have a polypropylene core and the 4-1⁄2″ outer diameter cartridges incorporate a spun polypropylene core. Sandwiched between the outer shell and the core is a bed of granular activated carbon (GAC).
Pentek RFC Series Cartridges are ideal for point-of-entry (POE) and other high flow rate applications.
