GrowoniX GXM-3000-HF High-Flow Replacement RO Membrane
The GrowoniX GXM-3000-HF is a 3000 GPD high-flow replacement membrane for GrowoniX's commercial CX-series reverse osmosis banks. It is a 4" x 40" polyamide thin-film composite element that moves up to 16 GPM, roughly 125 GPH. Each CX system stacks several of these elements, so you replace them as a set when rejection drops or output falls off. Chlorine tolerance stays under 0.1 ppm, so keep a working carbon prefilter upstream.
Fits the CX4000 through CX21000 Commercial Systems
This element fits the CX4000, CX6000, CX9000, CX12000, CX15000, CX18000, and CX21000 banks, not the GX or EX 1000-class systems that use the smaller GXM-1000 element. It runs across a 50°F to 113°F operating range. Chlorine destroys polyamide membranes, so never send chlorinated water straight into it. Swap elements when TDS creep or a drop in GPH tells you the membrane is spent.
