850 Float Switch GAC Reverse Osmosis System with Blending, TDS Meter and UV

Product Info

Built for serious coffee pros: this all-in-one beast delivers crystal-clear, perfectly mineralized water at 850 gallons per day—perfect for high-volume cafes, roasters, or espresso bars.

High-efficiency reverse osmosis strips out chlorine, metals, and scale first. Then the smart blending valve lets you dial in calcium/magnesium exactly—locking TDS to your 120-150 ppm sweet spot (SCA gold). Dual TDS meters track everything: inlet raw water on one, output on the other—so you see rejection rate and nail consistency every brew.

UV sterilizer kills bacteria, GAC carbon wipes tastes/odors. Float switch control auto-shuts when full—needs an atmospheric tank (required, sold separate) for steady flow. Compact, easy install, low-maintenance—keeps machines scale-free and shots on point.

Free shipping in the continental United States—restrictions apply.

Perfect for pour-over, espresso, batch: fruity Ethiopians pop, dark roasts stay bold without flatness.
