ABSTRACT:
A multi-function control component for use in dental vacuum systems includes, within a single housing, a vacuum control device for controlling the vacuum intensity within the system; a first air filter device for cleaning air permitted to enter the system by the vacuum control device; a second air filter for filtering gases flowing from an associated separating tank to a vacuum pump; a moisture detection device mounted in the housing for shutting down the vacuum pump drive motor upon detection of a predetermined level of moisture in the housing; a vacuum intensity measuring device; and a sealing device for sealing off the separating tank from the vacuum pump. The vacuum pump is a rotary vane pump, and is operatively connected to dental aspirator tips.
