Membrane compressed air dryer
max. 25 scfm | SUNSEP-W ™ series Twin Tower Engineering

At the heart of the SUNSEP-W ™ brand membrane air dryer technology is the patented membrane fibers developed by Asahi Glass Company (AGC) which has nearly 50 years of experience in the separation of gases with membranes.

The Sunsep drying process works by passing compressed air inside the hollow fiber membranes where the water vapor molecules permeate through the wall of the membrane leaving the oxygen and nitrogen molecules to exit the outlet as dry air. The permeated water vapor is then swept away by a small amount of dry air fed back over the outside of the membrane fibers through a purging valve or orifice.
