Product Description

Pentair FNS 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 fl ow restrictions, and therefore requires minimal pumping power to achieve a needed fl ow rate. That means lower utility costs. In addition to providing the clearest water possible, FNS 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.

Pentair's FNS unique, patented process creates a fiberglass reinforced tank with unequaled strength and durability unsurpassed for use in all high pressure applications. Curved, modular grid assembly permits maximum filtration surface in minimum area.

Featured Highlight

  • Sturdy tank clamp of premium stainless steel has permanent spring mechanism to correctly indicate proper tightness for securing tank halves
  • Water flows in bottom, up and around filter grid for even distribution of diatomaceous earth, eliminating bridging between elements and providing highly efficient filtration
  • Exclusive grid assembly with molded-in handles lifts out easily for inspection and periodic cleaning
  • Backwashes from top to bottom utilizing gravity for complete cleaning of accumulated dirt and D.E. powder
  • 2 in. bottom drain assembly permits unrestricted flow when draining filter

I need a replacement large o ring for Nautilus 180760. Since that part number is no longer available, what should I order?
