A system and method for separating air into components uses an air dehydration membrane for removing water vapor from compressed air. Dried compressed air is then directed, from the dehydration membrane, into a gas separation module which may be a membrane system, different from the air dehydration membrane, or a pressure swing adsorption (PSA) system. The air dehydration membrane is made of a hydrophilic polymer having a permeability for water vapor which is greater than its permeability for air, and having low selectivity between oxygen and nitrogen. The air dehydration membrane has a hydrophilic coating, which itself may be a polymer. The coating does not affect the selectivity of the coated dehydration membrane with respect to oxygen and nitrogen, but does increase selectivity of the membrane with respect to water vapor.
