  Pentair FNS Plus Vertical DE Filter
 


 
THIS IS A MAGNOLIA FAVORITE.  Ships same day!  We have dozens in stock of all sizes.  The FNS+ is  a fantastic, efficient, reliable filter capable of handling the smallest and largest jobs.  Call (888)570-PROS if you need any assistance sizing your FNS+ filter.

Filtering with diatomaceous earth (D.E.) 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 is1,000 microns!) Even though these particles can't be seen individually, collectively they greatly affect water clarity.
That's because D.E. filters remove the tiniest of contaminants...particles as small as 5 microns. (An average grain of sand is1,000 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. Our 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.

NOTE: You will also need the Pentair Backwash Slide Valve when you purchase this filter.
