Growonix Membrane 800 GPD High Flow Cold Water Membrane for EX800-T

GrowoniX 800 GPD High Flow Cold Water Membrane for the EX800-T This is the 3 in high flow membrane that drives the EX800-T, producing 800 GPD (33 gallons per hour) of nearly 0 ppm water at 97% rejection on a 1:1 ratio. It's a cold-water-optimized element, which matters more than most growers expect. RO output drops sharply as water cools, and this membrane is built to keep flow up where a standard element would stall. Cold Water RO Membrane Built to Hold Output in Winter Cold water is denser and more viscous, so it's harder to push through any membrane. Production can fall by roughly 50% between 77°F and 50°F, and the system ratio drifts toward the drain as feed water cools. This high flow cold water element is engineered to resist that drop, but it's still smart to check your system ratio through winter and, if needed, add a booster pump or warm the feed slightly to recover throughput. Drop it into your EX800-T as a direct replacement when rejection falls off or output no longer recovers after a flush. Key Features 800 GPD / 33 GPH: High output of nearly 0 ppm purified water for the EX800-T. 97% Rejection: Consistent contaminant rejection at a 1:1 system ratio. Cold Water Optimized: Holds production up better than standard elements when feed water runs cold. 3 in High Flow Element: The membrane size and design that the EX800-T is built around. Direct EX800-T Replacement: Drop-in element to restore output and rejection at end of membrane life.
