Pentair 60 SqFt Plus D.E. Filter

Pentair FNS® Plus 60 Sq. Ft. Vertical Grid D.E. Filter

The Pentair FNS® Plus 60 Square Foot Vertical Grid Diatomaceous Earth (D.E.) Filter is a premier, high-capacity filtration powerhouse engineered to achieve unmatched, commercial-grade water clarity for large residential swimming pools. Utilizing a curved vertical grid assembly coated with fine D.E. powder, this system provides 60 square feet of highly efficient filtration area capable of trapping microscopic particulate matter, dust, and algae down to an incredible 5 microns. The tank body is constructed from chemical-resistant, fiberglass-reinforced polypropylene, utilizing a unibody design that guarantees exceptional structural integrity under a continuous operating threshold of 50 PSI. Engineered with highly optimized internal hydraulics, it minimizes flow restriction to maximize hydraulic efficiency, easily handling a robust design flow rate of up to 120 gallons per minute (GPM) while working seamlessly alongside modern variable-speed pumps. Servicing the unit is streamlined by a heavy-duty tension control clamp band for quick tank access, a continuous High Flow™ internal air relief system, and a convenient bottom plug for rapid winterization. The side-port design leaves valve selection flexible, allowing integration with specialized multi-port or slide valves to match varying equipment pads. The dry shipping weight of the Pentair FNS Plus 60 D.E. Filter tank body is approximately 90 pounds (noting that it requires 6 pounds of standard D.E. filter powder for operational charging), making it a rugged, ultra-efficient centerpiece for pristine water management.
