ABSTRACT:
A dental office system including apparatus particularly adapted to high speed dental equipment. An aspirator operating valve having a coil spring trap catches inlays and crowns and other large pieces while permitting amalgum and other small pieces to pass without clogging the trap. A vacuum/venturi line avoids sludge buildup by constantly moving air through the lines. A water separator using a baffle arrangement avoids water creeping up the separator walls to reach and damage the vacuum pump. A slidable instrument console panel for ease of use by a dentist or his assistant includes automatic switches that operate when a dental handpiece is lifted.
