Marketing InformationPentair Pentek RFC series cartridges are constructed with a 70 um porous polyethylene outer shell and durable polypropylene endcaps. The 2-3/4 in OD cartridges have a polypropylene core and the 4-1/2 in OD cartridges incorporate a spun polypropylene core. Sandwiched between the outer shell and the core is a bed of granular activated carbon (GAC). The 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. Pentek RFC series cartridges are available in a wide variety of sizes and are ideal for point-of-entry (POE) and other high-flow rate applications.
