Features:
Provides effective chlorine taste & odor reduction
BB cartridges are ideal for point-of-entry (POE) and other high flow rate applications
Unique design reduces carbon fines in filtered water
Available in a wide variety of sizes
Reduces chlorine taste and odor in drinking water
Porous polyethylene 70-micron outer shell reduces carbon fines and other particles
Temperature range of 40 to 125 degrees F (4.4 to 51.7 degrees C)
Granular activated carbon (GAC) media with spun polypropylene core and polypropylene end caps for strength

RFC Series cartridges are constructed with a 25 micron porous polyethylene outer shell and durable polypropylene end caps. The 23⁄4" OD cartridges have a polypropylene core and the 41⁄2" 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.
Radial flow cartridges are ideal for 'whole house' or other point-of-entry applications due to their high flow rate and low pressure drop compared to standard GAC and carbon block cartridges
This Pentek RFC20-BB carbon filter cartridge reduces chlorine taste and odor in residential and commercial drinking water. It is made of granular activated carbon (GAC) media with a spun polypropylene core and polypropylene end caps for strength, and there is a nitrile butadiene rubber (Buna-N) gasket to ensure a watertight seal. The filter has a porous polyethylene 70-micron outer shell to reduce carbon fines and other suspended particles in the filtered water. It will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 75% in up to 70,000 gallons at a flow rate of 4 gallons per minute (gpm). The filter has an initial pressure drop of 0.90 pounds per square inch (psi) at a recommended flow rate of 4 gpm, and operates over a temperature range of 40 to 125 degrees F (4.4 to 51.7 degrees C). This carbon filter cartridge is used for treatment of residential and commercial drinking water.
