This flagship model utilizes an optimized internal layout featuring a symmetrical cluster of four premium, non-woven polyester cartridge elements. By splitting the work across four distinct cores, this design maximizes the total surface area to collect vast amounts of fine dust, suspended algae, and microscopic organic debris down to 20 microns. This immense dirt-holding capacity extends the operational timeframe between manual cleanings so significantly that most pool owners only need to service the filter once or twice a swim season. The massive, chemical-resistant tank body is injection-molded from a specialized fiberglass-reinforced polypropylene composite, creating a durable, UV-stable unibody shell that yields complete immunity to rust and harsh outdoor weathering under a maximum continuous operating pressure of 50 PSI. Because it captures all debris within the fabric pleats, the system operates flawlessly without ever requiring routine backwashing, effectively saving tens of thousands of gallons of treated, chemically balanced pool water over its lifespan. Equipped with high-flow internal hydraulics and 2-inch quick-connect bulkhead unions, the vessel reduces system backpressure to effortlessly accommodate a powerful maximum residential design flow rate of up to 150 gallons per minute (GPM), working in seamless synergy with modern variable speed pumps to minimize operational electricity costs. Routine service and offseason winterization are simplified by a heavy-duty, spring-loaded tension control clamp band for secure split-tank access, an integrated continuous High Flow™ internal air relief assembly, and an accessible 1.5-inch bottom drain plug for rapid cleanouts.
