ABSTRACT:
The membrane air dryer includes a housing with an air inlet adjacent a first end of the housing, an air outlet adjacent a second end of the housing, a sweep air inlet and a sweep air outlet. A membrane separator has surfaces extending between and connected to the air inlet and the air outlet. A first sweep air passage in the housing extends between the first and second ends of the membrane along and including surfaces of the membrane. The first sweep air passage has an inlet adjacent the air outlet and an outlet adjacent the air inlet and connected to the sweep air outlet. The sweep air inlet and outlet is adjacent the air inlet. A second sweep air passage in the housing extends between the first and second ends of the membrane. The second sweep air passage has an inlet that is connected to the sweep air inlet and is adjacent the air inlet and has an outlet that is adjacent the air outlet and in fluid communication with the inlet of the first sweep air passage. The membrane air dryer may be mounted to extend into the reservoir.
