Abstract
An air drying system for a vehicle including a membrane air dryer is provided. The air dryer is supplied with a stream of compressed air that has a low and constant concentration of oil vapor. A coalescing filter element may be used to maintain the oil vapor concentration. The filtered material may be discharged from the coalescing filter by a pressure swing drain valve, which discharges the filtered material upon unloading of the compressor.
