Abstract
A dental vacuum system includes a vacuum reservoir and at least one positive displacement dry vacuum pump operatively coupled to the vacuum reservoir to create a vacuum in the reservoir. One or more dental aspirators are coupled to the vacuum reservoir through a conduit system, whereby vacuum pressure developed in the reservoir by the pump is applied to the aspirators. The vacuum pump operates without a working fluid in its pumping chamber.
