Pentair FullFloXF™ Q120 High-Efficiency Cartridge-Style D.E. Filter

The Pentair FullFloXF™ Q120 High-Efficiency Cartridge-Style Diatomaceous Earth (D.E.) Filter (Product #: 188616) is an ultra-premium, heavy-duty hybrid sanitation vessel engineered to provide commercial-grade water polishing for large-scale residential pools and complex backyard water features. This advanced system represents a breakthrough in pool equipment design by blending the microscopic particulate-trapping capability of D.E. media—which strains fine dust, pollen, and algae down to an incredible 3 to 5 microns—with the physical layout and easy serviceability of a multi-element cartridge filter. Eliminating the fragile, curved fabric grids and complicated plastic manifolds found in traditional D.E. setups, the Q120 utilizes a symmetrical matrix of four heavy-duty cartridge elements totalizing 120 square feet of high-capacity filtration area, which pool owners can easily remove, rinse, and service like a standard cartridge filter. The massive tank body is injection-molded from a proprietary chemical-resistant, fiberglass-reinforced polypropylene composite, establishing a seamless, UV-stable unibody shell that yields permanent resistance to corrosion under a maximum continuous operating pressure of 50 PSI. Engineered with computer-optimized internal hydraulics and oversized 2.5-inch or 3-inch plumbing bulkhead connections, the vessel minimizes internal flow restriction to achieve up to 25% greater energy efficiency than conventional setups, effortlessly managing a powerful maximum design flow rate of up to 180 gallons per minute (GPM) in seamless harmony with modern variable speed pumps. Operations are simplified by a heavy-duty tension clamp band with an integrated safety gauge for secure split-tank access, an integrated continuous High Flow™ internal air relief system, and a convenient bottom drain plug for fast cleanouts or total winterization draining. The dry product weight of the Pentair FullFloXF Q120 Filter tank body is approximately 102 pounds (standing 42 inches tall with a tank diameter of 21.5 inches, noting that full operational configuration requires an initial media precoat charge of standard D.E. filter powder), delivering a structurally superior, eco-conscious, and ultra-high-performance centerpiece for pristine water clarity networks.
