Pentair FullFloXF™ F72 High-Efficiency Fiberglass D.E. Filter with 72 SqFt Filter Area

The Pentair FullFloXF™ F72 High-Efficiency Fiberglass Diatomaceous Earth (D.E.) Filter (Product #: 188621) is a premium, heavy-duty commercial-grade fluid-sanitation vessel engineered specifically to bring pristine clarity to large residential swimming pools, multi-featured aquatic installations, and demanding estate properties. Representing a major architectural leap in hydraulic efficiency, this advanced filter features a computer-optimized internal layout and a perfectly balanced fluid-distribution grid that generates exceptionally low system backpressure, achieving up to 25% greater energy efficiency than traditional high-capacity filters. This specialized low-restriction design allows the vessel to comfortably manage a powerful design flow rate of up to 144 gallons per minute (GPM) when paired with modern variable speed pumps, driving utility costs down while providing the unmatched water-polishing performance of D.E. media to trap dust, pollen, and microscopic particles down to an incredible 3 to 5 microns. The massive tank body is injection-molded from a proprietary fiberglass-reinforced polypropylene composite, creating a seamless, UV-stable unibody shell that yields permanent resistance to chemical corrosion, structural cracking, and harsh outdoor weathering under continuous working pressures up to 50 PSI. It comes equipped with extra-large 2.5-inch and 3-inch plumbing bulkhead unions to eliminate hydraulic bottlenecks across complex equipment pads, and features standard vertical curved grid elements designed for maximum structural stability and uniform precoat adhesion. Routine servicing and winterization are highly simplified by a heavy-duty, low-force tension clamp band for secure split-tank access, an integrated continuous High Flow™ internal air relief assembly, and an easy-access bottom drain plug. The dry weight of the Pentair FullFloXF F72 D.E. Filter tank body is approximately 102 pounds (standing roughly 53 inches tall with a compact 21.5-inch tank diameter, noting that full operational deployment requires an initial media precoat charge of 7.2 pounds of standard D.E. filter powder), delivering an exceptionally rugged, energy-conscious, and ultra-high-performance centerpiece for elite pool filtration networks.
