Pentair Quad DE Cartridge Style Filter

The Pentair Quad DE In-Ground Pool Filter provides the highest level of filtration out of all the filtration types available. It is capable of filtering out particulate as small as 5 microns. The Quad DE uses a set of 4 cartridges coated in pool grade diatomaceous earth to provide filtration. The Quad DE tank is made with fiberglass-reinforced polypropylene that enhances durability and product life. It uses a hi-flow manual air relief valve that eliminates air buildup in the tank rather than having it force back through the system.

A 1-1/2" drain is used for quick drainage, and a steel tension control clamp rests securely around the tank, a brass barrel nut securely fastens each half tightly together. Before removing the dome lid, it is suggested to backwash the filter to discharge the contaminated DE powder.

The Pentair Quad DE In Ground Pool D.E. Filter contains 4 cartridge style DE filter elements instead of the standard curved DE grids.
