The SpectraPure 180 GPD Flow Restrictor is a crucial component designed to regulate the wastewater flow in your reverse osmosis system. By creating the necessary back-pressure against the RO membrane, this restrictor ensures the system operates at its intended efficiency, maximizing purified water production while maintaining a proper rejection rate of total dissolved solids (TDS). It is specifically engineered to pair with reverse osmosis membranes rated for 180 gallons per day.

This standard flow restrictor is built to integrate seamlessly with most residential RO/DI systems that utilize 1/4-inch tubing. Proper flow restriction is vital for the health and longevity of your membrane, preventing issues like membrane scaling and premature failure. Without the correct GPD-matched restrictor, your system will not perform to specification, leading to excessive water waste and a lower quality of product water, which can negatively impact your aquarium's inhabitants.

This product is essential for aquarists who are building a new 180 GPD RO/DI unit or replacing a worn or incorrect flow restrictor on an existing system. It is a mandatory upgrade when changing your system's membrane to a 180 GPD capacity to guarantee peak performance and efficiency. For reef keepers who rely on ultra-pure water for mixing saltwater and for top-offs, this component is a small but critical part of a reliable water purification setup.
