This comprehensive replacement pack consists of eight pre-formed vertical grid elements matching the standard 24-inch technical height configuration: seven full-width curved grids and one specialized partial or \"small\" grid that accommodates the internal plumbing standpipe. Each individual element is injection-molded from virgin, high-impact styrene structural cores wrapped tightly in a chemical-resistant, multi-filament polypropylene fabric shroud with ultrasonically welded seams.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eIts primary operational role is to establish an expansive, high-surface-area foundation that uniformly captures fine Diatomaceous Earth powder, allowing the media to screen out organic contaminants down to an microscopic 5 microns while safely handling distribution velocities up to 96 GPM and sustaining continuous internal operating pressures up to 50 PSI without hydraulic bypass or fabric tearing under pump vibration surges. Engineered to endure decades of dynamic hydraulic stress and permanent submersion in a highly treated aquatic framework, this robust grid assembly completely resists premature blinding, fabric rot, and material degradation from concentrated pool sanitizers like chlorine, bromine, and winterizing acid flushes. Due to the combined mass of the high-impact polymer cores and tight-weave technical fabrics across all eight bundled units, this complete grid replacement pack carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"1\" data-index-in-node=\"960\"\u003e17.0 pounds\u003c\/b\u003e.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416200962159,"sku":"198082","price":499.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/5257230_2ee5ac52-b22d-4579-9efd-0b8bf373f87f.webp?v=1782744652","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-48-fns-plus-grid-replacement-pack","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
