Membrane Technology

Rainman systems utilize Reverse Osmosis technology at the core of the design.

Integrating DOW filmtech membranes and premium pre-filtration, the Rainman system can be operated in challenging environments where fresh, clean and safe drinking water is required.

​The below table illustrates the filtration spectrum of Reverse Osmosis systems compared to alternate means of filtration. 

"Completely portable, with no installation required for operation - 2 minute from storage to operational"

The Rainman System
​Component One
