ABSTRACT:
A compressed air drying apparatus employs a hollow fiber membrane dryer to provide a compressed air stream having a low dew point for outdoor use. Energy efficiency is obtained by purging water vapor from the hollow fiber membrane dryer with an adsorption-dried atmospheric air flow and by using a portion of the atmospheric air flow to regenerate the adsorption drying medium, preferably with heat from the compressor.
