With 36 sq ft of effective filtration surface and a 72 GPM flow rating, it is well suited for residential or light commercial pools that require robust, efficient filtration performance.\u003c\/p\u003e\n\u003cp data-start=\"2231\" data-end=\"2555\"\u003eThe tank is built of fiberglass‑reinforced polypropylene, giving superior resistance to corrosion and chemical degradation compared to traditional materials. The curved vertical grids increase the available filtration area, which helps trap dirt and debris more effectively and extends the time between required cleanings.\u003c\/p\u003e\n\u003cp data-start=\"2557\" data-end=\"2990\"\u003eKey design enhancements include the integrated Continuous High Flow™ internal air relief system and a high‑flow manual air relief valve — both of which prevent air buildup, ensuring consistent filtration performance. Backwashing is facilitated by a top‑to‑bottom flow path that more fully cleans the grid pack. The Service‑Ease™ grid pack simplifies maintenance by allowing grid removal one at a time, reducing effort and downtime.\u003c\/p\u003e\n\u003cp data-start=\"2992\" data-end=\"3291\"\u003eInstallation flexibility is aided by a sizeable bottom clean‑out port (1½\"), standard‑sized plumbing connections (2\"), and smart valve compatibility (valves sold separately). Operating limits include a maximum continuous pressure of 50 PSI, making this filter suitable for many common pool setups.\u003c\/p\u003e\n\u003cp data-start=\"3293\" data-end=\"3427\"\u003eIf you want crystal‑clear water, durable filtration, and reduced cleaning frequency, the Pentair 180007 FNS Plus is a strong choice.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":44134101155883,"sku":"180007","price":1109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/1589\/7131\/files\/PEN180007_0_392b71aa-62c5-4cf0-990f-27872249e125.png?v=1779954556","url":"https:\/\/auremontdirect.com\/products\/pentair-180007-fns-plus-36-sq-ft-de-filter-72-gpm-high-capacity-fiberglass-pool-filtration","provider":"Auremont Direct","version":"1.0","type":"link"}
