Growonix Membrane High Rejection 4 x 40 2700 GPD at 77F 225 psi, 98.5% Rejection

GrowoniX 2700 GPD High Rejection RO Membrane in 4 x 40 Format

This is a commercial 4 x 40 in element rated at 2,700 GPD with 98.5% rejection, measured at the industry-standard 77°F and 225 psi. The high-rejection design trades a little raw flow for cleaner permeate, so it's the membrane to run when low end-water PPM matters more than squeezing out every last gallon. It's manufactured in an ISO-9001 compliant facility with precision rolling for consistent, repeatable performance across elements.

Commercial 4 x 40 Membrane for High-Volume Water Purification

At 2,700 gallons a day this element feeds serious operations, and the 4 x 40 commercial format slots into GrowoniX systems built around that housing. Keep in mind the 2,700 GPD and 98.5% figures are rated at 77°F and 225 psi; cold feed water and lower line pressure will pull real-world output below the spec, so a booster pump and feed-temperature management keep it performing through winter. Swap it in as a direct replacement when your rejection rate climbs or production no longer recovers after a membrane flush.
