Nature2 Professional Purifier Vessel for 2" Plumbing - W25904
The Nature2 W25904 Professional G vessel is the housing for a compatible Nature2 G-series mineral cartridge in residential in-ground pools. This is the vessel only; the mineral cartridge is sold separately.
The vessel supports pools up to 45,000 gallons when paired with the appropriate cartridge: G25 for 10,000–25,000 gallons, G35 for 25,000–35,000 gallons, or G45 for 35,000–45,000 gallons. Match the cartridge model to the vessel label and pool size.
Connections are 2-inch PVC socket inlet and outlet or 1.5-inch female pipe thread. The manufacturer specifies a circulation-system flow rate of 30–120 GPM, an internal-bypass vessel flow rate of 10–18 GPM, and a maximum operating pressure of 50 PSI.
Follow the vessel installation manual and the separate cartridge owner’s manual for installation, activation, and the required low-chlorine care program. The six-month replacement interval applies to the mineral cartridge, not the vessel.
