More Surface Area for Better Pool Filtration and Less Maintenance

FNS Plus Pool Filters are designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. The internal design has been refined to minimize flow restrictions and, therefore, requires minimal pumping power to achieve a needed flow rate. This vertical-grid, D.E. filter is made of fiberglass-reinforced polypropylene for superior strength and reliability.

  • Superior strength
  • Service-Ease™ Grid Pack
  • Integrated Continuous High Flow™ Internal Air Relief*
  • Top-to-bottom backwash
  • High Flow Manual Air Relief Valve
 

Product Components

  1. Corrosion-resistant fiberglass tank for long life
  2. 2" plumbing connections for maximum flow
  3. Conveniently located 1" drain for easier and more efficient cleanout and 100% draining

Delivers Crystal Clarity

D.E. filters remove the tiniest of contaminants—particles as small as 5 microns (an average grain of sand is 1,000 microns). Just like a sponge, water can pass through, but microscopic impurities like dirt, algae and some forms of bacteria can’t.

 
 

Maximized Filtration, Minimized Costs

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.

Time-Tested Design

FNS Plus filters were also designed for easy maintenance, convenience and long-term reliability. So, you can count on them to keep your pool’s water clean and crystal clear for years to come.

180007, 180008, 180009: Flow rate is based on 2 GPM per sq. ft. of filter area. Actual system flow will depend on plumbing size and other system components. Valves must be purchased separately.

*Integrated Continuous High Flow Internal Air Relief is operational only when there is unobstructed flow in the circulating system.

Note: Operating limits—Maximum continual operating pressure of 50 psi. Pool/spa (bather) applications, maximum operating water temperature (internal filter) 104° F (40° C).
