Filter","description":"\u003ch2 data-path-to-node=\"0\"\u003ePentair Quad D.E.® 80 Sq. Ft. Cartridge Style D.E. Filter (EC-188593)\u003c\/h2\u003e\n\u003cp data-path-to-node=\"1\"\u003eThe Pentair Quad D.E.® 80 Square Foot Cartridge Style Diatomaceous Earth (D.E.) Filter (Product #: EC-188593) is an advanced hybrid pool filtration system engineered to deliver commercial-grade water polishing for large residential inground swimming pools. This innovative design combines the unparalleled particulate-trapping performance of diatomaceous earth—which filters out microscopic impurities, dust, and algae down to an incredible 5 microns—with the simple maintenance and high-flow layout of traditional cartridge systems. Rather than utilizing a complex, curved multi-grid nest that is famously tedious to disassemble, the Quad D.E. features a symmetrical four-cartridge internal grid assembly. These four heavy-duty, coreless polyester elements provide an evenly distributed surface area to support the D.E. precoat powder while allowing pool owners to easily remove, rinse, and service them like standard cartridge filters. The rugged tank body is injection-molded from a specialized chemical-resistant, fiberglass-reinforced polypropylene composite, forming a durable, UV-stable unibody shell built to withstand decades of harsh weather, chemical exposure, and continuous working pressures up to 50 PSI. Thanks to optimized internal hydraulics that minimize fluid restriction, the system effortlessly manages a powerful maximum design flow rate of up to 160 gallons per minute (GPM), working in seamless harmony with modern energy-saving variable speed pumps to drop overall monthly utility costs. Manual servicing is simplified by a rugged tension clamp band with an integrated mechanical spring-gauge for fast, tool-free split-tank access, alongside a continuous High Flow™ internal air relief assembly, an easy-to-read top pressure gauge, and a 1.5-inch bottom drain plug for fast cleanouts. Shipped with open side-mount bulkhead ports, it gives installers total flexibility to integrate custom 2-inch multiport backwash manifolds or slide valves. The dry product weight of the Pentair Quad D.E. 80 Filter tank body is approximately \u003cb data-path-to-node=\"1\" data-index-in-node=\"2051\"\u003e69 pounds\u003c\/b\u003e (with a boxed shipping weight of roughly 73 pounds, noting that full operational deployment requires an initial precoat charging of 8 pounds of standard D.E. filter powder), establishing a robust, low-resistance, and highly efficient cornerstone for pristine water clarity networks.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53159803813999,"sku":"188593","price":3179.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/pentaircleanclearplus-160340_cdf6448b-8934-4da0-a839-3257e7032081.png?v=1779822410","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-80-sqft-quad-cartridge-style-d-e-filter","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
