This is a 20″ x 2-7/8″, 5 micron Pentek EP carbon block water filter. EP Series carbon briquette cartridges are manufactured using a patented process that yields a cartridge with a nominal 5-micron filtration rating, high dirt-holding capacity. A high porosity design helps prevent the cartridge from plugging before its adsorption capacity is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. Pentek EP 20″ 5 Micron Carbon Block Filters These cartridges are protected by Endurawrap, a uniquely formulated polyolefin bilaminate pre-filter designed to significantly increase the cartridge’s useful life by trapping sediment that typically plugs carbon block cartridges. EP Series cartridges are manufactured entirely from FDA-compliant materials, making them ideal for a wide range of residential, food service, commercial, and industrial applications. Pentek is the: largest brand in the filtration industry originator of carbon block production technology largest producer of carbon blocks worldwide Model Maximum Dimensions Nominal µm Rating* Initial ΔP @ Flow* Chlorine Capacity @ Flow* EP-10 9-3/4″ × 2-7/8″ 5 µm 3.4 psid @ 1.0 GPM >6,000 gal @ 1.0 GPM EP-20 20″ × 2-7/8″ 5 µm 3.4 psid @ 2.0 GPM >12,000 gal @ 2.0 GPM EP-BB 9-3/4″ × 4-5/8″ 5 µm 4.3 psid @ 2.0 GPM >22,000 gal @ 2.0 GPM EP-20BB 20″ × 4-5/8″ 5 µm 5.5 psid @ 5.0 GPM >40,000 gal @ 4.0 GPM * Based on manufacturer’s internal testing.
