Pentair 500 32 1/2" SqFt Modular Media Filter

Pentair Sta-Rite® System:3® S8M500 / PLD Series 500 Sq. Ft. Modular Media Filter (32.5" Diameter)

The Pentair Sta-Rite® System:3® S8M500 is a commercial-grade, ultra-capacity 500 square foot modular media cartridge filter meticulously engineered to deliver crystalline water clarity for large-scale residential inground swimming pools, commercial water park features, and high-volume institutional aquatic facilities. Featuring a distinctively broad 32.5-inch tank diameter, this system utilizes a dual-concentric modular cartridge configuration comprising a perfectly matched inner and outer pleated element matrix. This advanced architectural design maximizes total surface area utilization to capture fine dust, organic contaminants, and microscopic debris with up to 15 times greater dirt-loading capacity than traditional sand filters of equivalent size, radically reducing manual cleaning intervals and conserving water by eliminating the need for routine backwashing altogether. The two-piece tank housing is injection-molded from Dura-Glas®, a proprietary high-density fiberglass-reinforced composite resin that provides absolute immunity to chemical corrosion, long-term UV weathering, and structural fatigue under a maximum continuous operating pressure of 50 PSI. Its highly balanced, computer-optimized internal flow distribution profile comfortably supports a maximum design flow rate of up to 130 gallons per minute (GPM), allowing it to work in flawless harmony with modern energy-saving variable speed pumps to lower overall utility costs. Maintenance is simplified by an easy-access split-tank design secured by heavy-duty, low-profile Posi-Lok™ clamps that allow tool-free access to the internal media, paired with a top-mounted dual-view pressure gauge and manual air relief system. The dry product weight of the Pentair System:3 S8M500 500 Sq. Ft. Modular Media Filter is approximately 122 pounds (with a boxed shipping weight of roughly 147 to 150 pounds), providing pool professionals and estate owners with an incredibly stable, robust, and hydraulically superior powerhouse for pristine water quality management.
