Pentek EPM-20BB Carbon Block Filter Cartridge, 20' x 4-5/8', 10 Microns: Industrial & Scientific. Buy Pentek EPM-20BB Carbon Block Filter Cartridge, 20" x 4-5/8", 10 Microns: Replacement Under-Sink Water Filters - ✓ FREE DELIVERY possible on eligible purchases. none 。 Imported 。 Reduces fine sediment and chlorine taste and odor in residential and commercial drinking water 。 Nominal filtration rating of 10 microns 。 Bonded PAC media with polyolefin pre-filter and polyethylene netting for extended life 。 Initial pressure drop of 4 psi at a flow rate of 4 gpm 。 Temperature range of 40 to 180 degrees F (4.4 to 82.2 degrees C) 。 This EPM-20BB carbon block filter cartridge reduces fine sediment and chlorine taste and odor in residential and commercial drinking water. It has a nominal (85%) filtration rating of 10 microns. The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 90% in up to 30,000 gallons at a flow rate of 4 gallons per minute (gpm). This cartridge is made of bonded powdered activated carbon (PAC) filter media wrapped in polyolefin with polyethylene outer netting. The nitrile butadiene rubber (Buna-N) gaskets seal the cartridge against the housing (sold separately). The cartridge has an initial pressure drop of 4 pounds per square inch (psi) at a flow rate of 4 gallons per minute (gpm), and operates over a temperature range of 40 to 0 degrees F (4.4 to 82.2 degrees C). This carbon block filter cartridge meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is used for purification of residential and commercial drinking water.。SpecificationsNominal filtration rating10 micronsInitial pressure drop at 4 gpm4 psiChlorine reduction capacity30,000 gallons at 4 gpmTemperature range40 to 0 degrees F (4.4 to 82.2 degrees C)Maximum dimensions (H x W)20 x 4-5/8 inches (508 x 1 mm)Materials certificationNSF/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 the free available chlorine (FAC) at a concentration of 2 ppm is reduced by at least 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 horizontal distance from front to back.。Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.。Pentair manufactures industrial, commercial, and residential water filtration components and systems. The company, founded in 1966 and headquartered in Minneapolis, MN, meets International Organization for Standardization (ISO) standards 9001 and 14001 for quality assurance.。 。 。 。
