ABSTRACT:
An apparatus is provided for supplying vacuum and compressed air utilities for dental and medical applications. The apparatus comprises a reciprocating piston air compressor for simultaneously producing vacuum pressure at an intake valve thereof and compressed air at an exhaust valve thereof, the vacuum being used to draw air, water vapor, and effluent such as bodily fluids and tissue through a conduit. Effluent and water vapor are separated from the air stream and discharged into a drain. The desired vacuum is maintained by a regulator carried by the compressor. A receiver is also carried by the compressor for receiving and storing the compressed air from the compressor.
