The Tsunami membrane drying system requires no electricity and comes ready to install for applications requiring clean dry oil free air. After the air passes through the Tsunami Automatic Water Separator & Oil Coalescer it goes into the membrane dryer which removes water vapor and lowers the dew point of the air. A precision air regulator then reduces pressure to you requirements. The ½” ball valve included in the system allows the inlet air to be shut off when system is not in use, preventing wasting air.
