Pentair FNS Plus D.E. Filters Item: PENTAIR_FNS-PLUS

Product Line Information | Show Products From This Line ▼

Filtering with diatomaceous earth (D.E.) gives you water that really sparkles. Thats because D.E. filters remove the tiniest of contaminants. . .particles as small as 5 microns. (An average grain of sand is 1000 microns!) Even though these particles can't be seen individually, collectively they greatly affect water clarity. Here's why diatomaceous earth filters work so well. Water passes through a series of D.E. coated grids. Under a microscope, D.E. looks like a collection of tiny sponges. And just like a sponge, water can pass through, but microscopic impurities like dirt, algae, and some forms of bacteria can't.

FNS® Plus D.E. Filters have been designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. Pentair's exclusive internal design has been refined to minimize flow restrictions and, therefore, requires minimal pumping power to achieve a needed flow rate. That means lower utility costs!

In addition to providing the clearest water possible, FNS Plus was also designed for easy maintenance and long-term reliability. So you can count on it to keep your pool water clean and crystal clear for years to come.

The filter that delivers crystal clarity, FNS® Plus Filters feature the same, superior curved grid design as the FNS®, but with a fiberglass reinforced polypropylene body for advanced chemical resistance and superior strength. It also includes Service-Ease grid pack, high flow manual air relief value, and tension control clamp. 100% factory tested.
