A membrane air dryer includes a housing with an air inlet, an air outlet, a sweep air inlet and a sweep air outlet; and a membrane separator having surfaces extending between and having an inlet and an outlet respectively connected to the air inlet and the air outlet. A sweep air passage in the housing extends between first and second ends of the membrane along and includes surfaces of the membrane. The sweep air passage has an inlet adjacent the air outlet and has an outlet adjacent the air inlet and connected to the sweep air outlet. A volume is concentric to the membrane separator, has an inlet connected to the outlet of the membrane separator and has an outlet connected to the sweep air inlet. The filter may be mounted in a reservoir with the membrane separator extending into the reservoir.
A membrane air dryer comprising:
A combination of a reservoir having a reservoir inlet and a membrane separator having a housing with a separator member between an air inlet and an air outlet, a sweep air passage having a sweep air inlet and a sweep air outlet and a volume housing defining a volume fluidally connecting the air outlet to the sweep air inlet, wherein the housing extends from the reservoir inlet into an interior of the reservoir so that the air inlet and sweep air outlet are exterior to the reservoir and the air outlet, and the membrane separator and the volume are interior to the reservoir.
