The Pentair FNSP48 FNS Plus DE Filter gives you water that really sparkles. That’s because D.E. filters remove the tiniest of contaminants—particles as small as 5 microns (an average grain of sand is 1,000 microns). Even though these particles can’t be seen individually, collectively they greatly affect water clarity.
Here’s why D.E. 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 filters have been designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. Our 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. The FNS Plus filters were also designed for easy maintenance and long-term reliability.
- Curved vertical grids provide maximum filter surface area for greater dirt-trapping capacity and longer periods between cleanings.
- Internal design ensures optimum filtration and backwashing efficiency.
- Chemical-resistant, fiberglass-reinforced polypropylene tank for exceptional strength and longer life.
- Easily removable filter grid pack to simplify maintenance and save you time.
