Pentair FNS Plus 36 sq ft DE Filter | EC-180007

The Pentair FNS Plus 36 sq. ft. D.E. (Diatomaceous Earth) Filter is engineered to deliver the highest possible level of water filtration. While sand and cartridge filters catch large particles, D.E. filters remove microscopic contaminants as small as 3–5 microns, resulting in water that is literally polished and sparkling clear. The EC-180007 model features a curved vertical grid design that provides a massive surface area for D.E. powder, ensuring your pool stays pristine even during heavy bather loads or high-pollen seasons.

Features

Micro-Micron Filtration: D.E. is the most effective filtration media available, stripping your pool water of fine silt, algae, and microscopic debris that other systems simply cannot catch.

Curved Vertical Grid Design: Specifically engineered to provide balanced water flow and even D.E. coating across the entire grid surface, maximizing dirt-holding capacity and extending the time between backwash cycles.

Fiberglass-Reinforced Polypropylene Tank: The high-strength, chemical-resistant tank is UV-stabilized and built to withstand the toughest outdoor conditions and high-pressure operation for years of service.

High-Flow Manual Air Relief: Includes Pentair’s specialized High Flow™ manual air relief valve and a continuous internal air relief to ensure safe operation and consistent pressure levels.

Service-Friendly Design: The tension control clamp allows for quick and safe access to the internal grid assembly for seasonal deep-cleaning and inspections.

2" Plumbing Connections: Large 2-inch bulkhead unions reduce flow resistance, allowing your pool pump to operate more efficiently and move more water with less energy.
