At Brewing Water, we offer two versions of the 500 GPD Reverse Osmosis System tailored for the Coffee brewing industry. Both systems come equipped with a blending valve and a dual TDS meter, giving you precise control over your water’s total dissolved solids. The difference? One system features GAC carbon filtration, while the other offers catalytic carbon (CAT carbon) for broader contaminant reduction. Both systems also include a 20-inch sediment filter and two 20-inch GAC carbon filters (for the GAC version). Pair either with a pressure tank, and you have a complete water solution. Free shipping is included within the continental U.S., though restrictions may apply.
