Pentair FNS Plus

The Pentair FNS Plus D.E. Filter Systems have been designed to remove particles so small they are individually undetectable by the human eye, providing the clearest possible water. Their exclusive internal design ensures optimum filtration and backwashing efficiency. An easily removable curved filter grid pack simplifies maintenance and because they're designed to extend the time between cleanings, you can spend more time enjoying your pool instead of maintaining it. A high flow manual air relief valve and continuous internal air relief valve work together to maintain the filtration and prevent over-pressurization. The FNS Plus offers a unique design for a more efficient filter system with maximum performance, convenience, and reliability with minimal utility costs. The fiberglass reinforced polypropylene tank provides exceptional strength and long life for a sparkling clean and clear pool environment.

Here’s why diatomaceous earth filters work so well. The 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. Our exclusive internal design has been refined to minimize flow restrictions, therefore requiring minimal pumping power to achieve a needed flow rate, lowering your utility costs.
