Radial Flow Carbon 20 in, Big Blue

Pentair® Pentek® RFC Series Cartridges are constructed with a 70-micronporous 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 granularactivated carbon (GAC). The unique radial flow design offers the benefits of granular activatedcarbon (GAC) filtration, such as low pressure drop, while at the same timesignificantly reducing the release of carbon fines commonly associatedwith GAC-style cartridges. Pentek RFC Series Cartridges are available in a wide variety of sizes andare ideal for point-of-entry (POE) and other high flow rate applications.
