A fresh approach to desalination


Petrol or Electric

Rainman Watermakers are a compact and portable solution designed to generate a fresh water supply from salt or brackish water. Our 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 PSU comes in 240v, 12VDC or Petrol option and can be paired with single 21″ membranes up to twin 40″ membranes.

The optional Rainman flow gauge allows our system to be used in brackish or fresh water applications.

Portable or Installed

Although the Rainman watermaker was originally designed as a portable system not requiring installation, many of our customers choose to partially or fully install the system in their boat. The variations can range widely, including installation of both the pressure supply unit and reverse osmosis case to installing one or the other of the units.

Built to last

Using 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.


Our system can easily be transferred between boats, for caravanning, camping and fishing trips. You can even use Rainman as a salt water pressure washer with our optional pressure gun attachment.
