Abstract
A dental vacuum assembly utilizes a rotary vane vacuum pump. The pump is operatively connected to a vacuum reservoir and driven by an electric motor commonly mounted with the pump on a vibration-isolated platform. The vacuum reservoir is operatively connected to a number of different dental stations, each including a dental aspirator tip. The vacuum reservoir is supported by a support component which receives a drain valve in the bottom of the vacuum reservoir, and has a false bottom connected to a drain pipe section which extends through a side wall of the support component for easy connection to a sewer.
