The system consists of a Pressure Supply Unit (PSU); which pressurizes the source water, and a Reverse Osmosis Unit; which desalinates the water with a membrane, removing impurities and creating fresh potable water. The optional Rainman flow gauge enables the system to be used in brackish or fresh water applications.
