SPX Flow Hankison Membrane gas separation technology, previously used to generate nitrogen, is widely used for compressed air drying. It is simple and reliable. Compressed air, saturated with water vapor, flows through a bundle of tube-shaped membranes then the water passes through the membrane walls. Dry air then exits the tube bundle for use downstream.
