GrowoniX EX1000 1000 GPD High Flow RO System with 1:1 Ratio

The EX1000 produces 1000 GPD (42 gallons per hour) at a 1:1 waste-to-pure ratio, so you get a gallon of purified water for every gallon sent to drain. It runs the best DOW membrane technology at up to 98.5% rejection and uses a high flow cold water membrane that trades a touch of rejection for much stronger output, which is exactly what you want when feed water runs cold. It operates on 40 to 80 psi of incoming pressure and handles feed water from 40°F to 90°F.

KDF85/CAT Carbon and Dual Stainless Gauges for Big Rooms

This KDF build includes the KDF85/CAT carbon filter for both chlorine and chloramine reduction, the cartridge to run when your municipal water is chloraminated. A pair of liquid-filled stainless steel pressure gauges reads the differential across the pre-filters so you change them when the pressure tells you to, not on a guess, and a manual flush valve purges the membrane to clear buildup and extend its life. Need more throughput? Add a booster pump to raise system pressure to 150 psi and roughly double the daily output. Mount it, plumb your feed and drain, and it's ready to run.

Key Features

• 1000 GPD / 42 GPH: High-volume output for large grow rooms and reservoir fills.
• 1:1 Waste Ratio: One gallon of pure water per gallon of waste for efficient production.
• Cold Water Membrane: High flow element that holds output up when feed water runs cold.
• Up to 98.5% Rejection: DOW membrane technology for near-zero-PPM purified water.
• KDF85/CAT Carbon: Reduces both chlorine and chloramine from municipal feed water.
• Dual Stainless Pressure Gauges: Liquid-filled gauges show when pre-filters need changing.
• Booster-Pump Ready: Raises pressure to 150 psi to roughly double daily output.
