• Replaces Pentek® CP and HFCP series cartridges Special formulation of resin impregnated cellulose and polyester fibers Provides higher wet strength than regular cellulose cartridges Minimal unloading and media migration 1 psi at 20 gpm initial pressure drop White vinyl plastisol standard endcaps, polypropylene big blue endcaps and core

Pentair Pentek ECP series cartridges are manufactured from a special formulation of resin impregnated cellulose and polyester fibers. This unique blend of materials provides a higher wet strength than regular cellulose cartridges. It also provides high-flow rates and dirt-holding capacity, while maintaining extremely low-pressure drop. The media is pleated around a polypropylene core for added strength. The pleated endcaps of-the standard cartridges are immersed in a thermosetting vinyl plastisol. The big BLUE® cartridges have a molded endcap with gaskets. The pleated ends are sealed to the endcap with a thermoplastic adhesive. The overlap seam is sonically welded to reduce internal bypass, improving filtration efficiency. ECP series cartridge endcaps feature a color-coding system for easy identification of micron ratings tan (1 um), white (5 um), blue (20 um) and yellow (50 um).
