Quad D.E.^®

Filters by Pentair

The crystal clarity of D.E. with cartridge convenience

Quad D.E.^® Filters provide the highest water clarity of D.E. with the convenience and easy-cleaning features of a cartridge filter. Four easily accessible and removable D.E. cartridges greatly increases the filter's cleaning capacity. And, cleaning couldn't be easier. In fact, you have three options…backwash and recharge like a traditional D.E. filter, remove and rinse off the cartridges, or simply remove the lid, leave the cartridges in place, open the drain plug, and rinse. You'll even save money—water flows through the Quad D.E.^® Filters so efficiently less pumping power is needed.

An Eco Select^™ Choice: Water flows very efficiently through Quad D.E.^® Filters filters allowing the use of smaller pumps or lower pump speeds to minimize energy use. And when consumers rinse cartridges rather than backwash, they can significantly reduce water use, too.

Features

Four large-capacity cartridges provide maximum filter surface area for greater dirt-trapping capacity and longer periods between cleanings
Unique internal flow path ensures optimum filtration and backwashing efficiency
Chemical resistant, fiberglass reinforced polypropylene tank for exceptional strength and long life
Easily removable cartridge elements make maintenance fast and easy
Water flows through the Quad D.E.^® Filters so efficiently that your pump will use less energy
You need to also purchase the backwash valve or the bulkhead kit to install your filter.
