Pentair Ecp Series — Pleated Cellulose Polyester Cartridges
Resin-impregnated cellulose/polyester pleated sediment cartridges for residential, commercial, and industrial water filtration. Pleated media wrapped around a polypropylene core delivers higher wet strength than standard cellulose cartridges, low pressure drop, high dirt-holding capacity, and minimal media unloading. Endcaps are color-coded by micron rating for quick identification.
