Puretec ROS Series

Continuous Flow Reverse Osmosis System

Puretec ROS2700 Series represents a revolutionary breakthrough in the water treatment industry. This new reverse osmosis system features continuous-flow water production, a storage tank is no longer required.


This unit operates on line pressure, which eliminates the need for an electrical pump in most applications. It uses water pressure to reverse a natural physical process called osmosis. Water under pressure, is forced through a semi-permeable membrane to filter out minerals and impurities.
