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.
ECP cartridges contain more media surface area than most competitive cartridges. For example, our standard 10" ECP Cartridge contains six square feet of media, where most competing cartridges contain only 4.5 square feet.
