The FNS Plus uses curved vertical grids that maximize filtration area, which adds dirt trapping capacity and extends the time between cleanings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConstruction and maintenance\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tank is chemical resistant, fiberglass reinforced polypropylene for strength and long service life. A top manifold design pairs with a Service-Ease grid pack so the full grid pack can be removed and serviced without disturbing other components. A high flow manual air relief valve works with continuous internal air relief to maintain efficient filtration and prevent over-pressurization, and a 2 in. drain makes cleanout easier.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is an almond colored, full grid, in-ground filter, part number 180007.
