Claim:
1. A rotary adsorbent dryer including a stationary outer housing having spaced stationary end walls, a rotor rotatably mounted within said outer housing for rotation about a rotation axis, the rotor having substantially open opposed ends, each of which is positioned adjacent to a respective one of the end walls of the outer housing, a plurality of first compressed gas flow passages passing through the end walls providing, in use, compressed gas flow to or from a respective substantially open end of the rotor, and a drive arrangement for rotating the rotor about the rotation axis, the drive arrangement being cooperable with an outer circumferential region of the rotor, wherein the drive arrangement provides discontinuous movement of the rotor whereby the rotor is stationary for a predetermine period of time between periods of discontinuous rotational movement.
