Rainman Watermaker – Portable Fresh Watermaker

Rainman Watermaker – Water Everywhere

A compact and portable solution designed to generate a fresh water supply from salt or brackish water. 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.

Built to last

We use only top quality components from the best manufacturers: Honda, DOW FILMTEC, General Pump, Jabsco. Our ﬁlters, membranes and replacement parts are non-proprietary for ease of service worldwide.

Versatile

Our system can easily be transferred between boats or used in remote land based locations. You can even use Rainman as a salt water pressure washer with our optional pressure gun attachment.
