Detail
This Pentek CRFC20-BB carbon filter cartridge reduces chlorine and chloramine in residential and commercial drinking water. It has nominal filtration rating of 20 microns at an efficiency of 85%. The cartridge is made of granular activated carbon (GAC) media with a spun polypropylene inner wrap for post filtering of carbon fines and a porous polyethylene outer shell. A Santoprene gasket provides a watertight seal. The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 75% in up to 200,000 gallons at a flow rate of 4 gallons per minute (gpm), and reduce 3 ppm chloramines by at least 75% in up to 25,000 gallons at a flow rate of 2.5 gpm. The filter has an initial pressure drop of 2.5 pounds per square inch (psi) at a recommended flow rate of 5 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.
