This Pentek EP-20BB carbon block filter cartridge reduces fine sediment andchlorine taste and odor in residential and commercial drinking water. It has anominal (85%) filtration rating of 5 microns. The filter will reduce freeavailable chlorine (FAC) at 2 parts per million (ppm) by at least 90% in up to40,000 gallons at a flow rate of 4 gallons per minute (gpm). This cartridge ismade of bonded powdered activated carbon (PAC) filter media wrapped in apolyolefin pre-filter with polyethylene outer netting. The nitrile butadienerubber (Buna-N) gaskets seal the cartridge against the housing (soldseparately). The cartridge has an initial pressure drop of 5.5 pounds persquare inch (psi) at a flow rate of 5 gallons per minute (gpm), and operatesover a temperature range of 40 to 180 degrees F (4.4 to 82.2 degrees C). Thiscarbon block filter cartridge meets National Sanitation Foundation/AmericanNational Standards Institute (NSF/ANSI) standard 42 for quality assurance, andis used for purification of residential and commercial drinking water. Specifications Nominal filtration rating 5 microns Initial pressure drop at 5 gpm 5.5 psi Chlorine reduction capacity 40,000 gallons at 4 gpm Temperature range 40 to 180 degrees F (4.4 to 82.2 degrees C) Maximum dimensions (H x W) 20 x 4-5/8 inches (508 x 118 mm) Materials certification NSF/ANSI standard 42 The nominal filtration rating is for a particle removal efficiency of 85%.Chlorine reduction capacity is the minimum total amount of water for which thefree available chlorine (FAC) at a concentration of 2 ppm is reduced by atleast 90%. H is height, the vertical distance from lowest to highest point; W is width,the horizontal distance from left to right; D is depth, the horizontaldistance from front to back. Water filters remove undesirable particles, chemicals, and microorganisms fromwater by means of a semipermeable barrier, adsorption, or biologicalprocesses. They are made of densely packed synthetic or natural fibers thattrap suspended particles, materials that block microbes or adsorb unwantedchemicals, or substances that cause a chemical change, such as acidneutralization. For most residential, commercial, and industrial applications,water filters are manufactured in the form of replaceable cartridges that fitinside permanent housings. Filtration systems typically consist of a series oftwo or more types of filters, each designed to remove different contaminants.The performance of filters is measured by the minimum particle size that isblocked, the percentage of particles or microorganisms that are removed, thedownstream concentration of unwanted chemicals, the maximum flow rate, and theamount of water that can be filtered before the filter must be replaced. Waterfilters are used in a wide range of applications, including drinking waterpurification, swimming pools, industrial processes, and irrigation, amongothers. Pentair manufactures industrial, commercial, and residential water filtrationcomponents and systems. The company, founded in 1966 and headquartered inMinneapolis, MN, meets International Organization for Standardization (ISO)standards 9001 and 14001 for quality assurance.
