    Pentair FNS® Plus diatomaceous earth (D.E.) filters provide you with superior water clarity and self-cleaning convenience with minimal effort!

    The filter removes particles so small they are individually undetectable by the human eye – but collectively combine to decrease water clarity. In addition to providing the clearest possible water, FNS® Plus was also designed for easy maintenance and long-term reliability.

    FNS® Plus features curved vertical grids that will provide the maximum filter surface area for greater dirt-trapping capacity and longer periods between cleanings.

    With a unique internal design, the Pentair FNS® Plus ensures optimum filtration and backwashing efficiency. An easily removable filter grid pack simplifies maintenance and a High Flow™ manual air relief valve and continuous internal air relief valve work together to maintain efficient filtration and prevent over-pressurization. The fiberglass reinforced polypropylene tank provides exceptional strength and long life.

    All FNS® Plus Systems are powered by the Pentair SuperFlo™ pump and come complete with filter tank, 6-way multi-port valve and pressure gauge.

    PUMP TO FILTER FITTINGS ARE NOT INCLUDED.
