Pentair Pentek ECP5-20BB Polyester Pleated Sediment Filter 20" Large Diameter 5 micron (255494-43)

Pentair Pentek ECP Series Cartridges are manufactured from a special formulation of resin-impregnated cellulose and polyester fibres.

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 thermo-setting vinyl plastisol. The Big Blue cartridges have a moulded 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.
