Pentair 60 SqFt Quad Cartridge Style D.E. Filter

Pentair Quad D.E.® 60 Sq. Ft. Cartridge Style D.E. Filter (EC-188592)

The Pentair Quad D.E.® 60 Square Foot Cartridge Style Diatomaceous Earth (D.E.) Filter (Product #: EC-188592) is an elite, high-efficiency hybrid filtration system designed to bring exceptional commercial-grade water polishing to medium-to-large residential inground swimming pools. This innovative system combines the unparalleled microscopic filtering performance of diatomaceous earth—which traps microscopic dust, pollen, and algae down to an incredible 5 microns—with the physical ease and high-flow efficiency of traditional cartridge technology. Bypassing the traditional, complex curved multi-grid assembly that is notoriously tedious to disassemble and clean, the Quad D.E. utilizes a symmetrical four-cartridge internal matrix; these four heavy-duty polyester coreless elements support the D.E. precoat evenly while allowing users to easily remove, rinse, and service them like standard cartridges. The rugged filter housing is injection-molded as a single piece from chemical-resistant, fiberglass-reinforced polypropylene, establishing a durable, UV-stable unibody shell that can comfortably withstand weathering, chemical imbalance, and continuous working pressures up to 50 PSI. Because water flows through the pleated fabric with minimal internal restriction, the filter boasts highly optimized hydraulics that support a maximum residential design flow rate of up to 120 gallons per minute (GPM), working in seamless efficiency with modern energy-saving variable speed pumps to minimize utility costs. Manual maintenance and off-season storage are highly streamlined by a rugged tension clamp band with an integrated mechanical spring-gauge for rapid split-tank access, a continuous High Flow™ internal air relief assembly, and a convenient 1.5-inch bottom drain plug for fast cleanouts. Shipped open with side-mount bulkhead ports, it offers ultimate installation flexibility for pool builders to integrate high-flow multiport backwash valves or slide valves. The dry product weight of the Pentair Quad D.E. 60 Filter tank body is approximately 70 pounds (noting that a full operational deployment requires an initial charging of 6 pounds of standard D.E. filter powder), delivering pool owners an exceptionally rugged, low-resistance, and highly advanced centerpiece for pristine water clarity networks.
