RAINMAN High output Reverse Osmosis Case


Our highest output RO system is compatible with either the petrol (gasoline) or AC electric pressure supply units.

Water Everywhere
Rainman watermakers are a compact and portable solution designed to generate a fresh water supply from seawater.
Our system consists of a Pressure Supply Unit (PSU) and a Reverse Osmosis Unit (RO). The PSU draws water up, filters it, and pressurises it for the RO unit, which extracts fresh potable water for your tanks. With the brackish water flow gauge, you can use the system in seawater, brackish water, or freshwater applications.

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

Our system can be easily transferred between boats or used in remote land based applications. Keep your watermaker when you change your boat.

The Rainman Advantage
Our simple and robust system is designed for ease of use and low maintenance. This fresh approach to desalination eliminates unnecessary componentry and electronics. Not only will the initial cost of a Rainman watermaker be lower than other systems, but the simple design and high build quality reduces ongoing maintenance costs.

Choose to install your system or run it portable, allowing you to reduce weight while not cruising.

Using simple pumps and no electronics maximises the uptime of your watermaker.

Modest initial price and low maintenance requirement minimises life cycle cost.

High output
Up to 140 litres per hour (37 gph).

Investment retention
Keep your watermaker when you change boats.
