Pentair FNS® Plus Filter

Experience superior water clarity with Pentair Quad D.E.® Filters. These filters combine the fine filtration power of Diatomaceous Earth (D.E.) with the convenience of a four-cartridge system. This design traps microscopic impurities, algae, and some forms of bacteria, delivering exceptionally sparkling clear pool water. The four-cartridge configuration increases the filter's surface area, extending the time between cleanings and ensuring efficient operation.

• Exceptional Water Clarity: D.E. filtration captures particles as small as 5 microns, providing the clearest possible water.
• Four-Cartridge Design: Maximizes filter surface area for greater dirt-trapping capacity and longer cycles between cleanings.
• Convenient Maintenance: Offers multiple cleaning options, including backwashing (if valved) or easy removal and rinsing of the four D.E. cartridges.
• Durable Construction: Features a chemical-resistant, fiberglass-reinforced polypropylene tank for exceptional strength and long life.
• Efficient Flow: Designed for optimal internal flow, which can lead to energy savings by allowing the pump to operate at lower speeds.

Key features and operational notes for Pentair Quad D.E.® Filters:

• Hybrid Technology: Combines the particulate-trapping ability of D.E. with the easy-to-service nature of cartridge filters.
• Cleaning Options: Depending on your setup and preference, you can backwash and recharge with D.E. (requires a multiport or slide valve, sold separately), or remove the four internal D.E. coated cartridges for manual rinsing.
• Extended Cleaning Cycles: The large surface area provided by the four D.E. coated cartridges means longer periods before cleaning is required compared to some other filter types.
• Manual Air Relief: Equipped with a high-flow manual air relief valve to easily vent trapped air from the system, ensuring optimal performance.
• Valve Requirement: For backwashing functionality, a compatible multiport or slide valve must be purchased and installed separately.
• D.E. Application: After cleaning or backwashing, new D.E. powder must be mixed into a slurry and added to the system (typically through the skimmer) to coat the cartridges.
