Abstract

A dental evacuation unit has a plurality of evacuation devices, each of the devices being connected to a common separator by its respective debris conducting line, and each line having a venturi located therein. Gas supply means are provided for selectively directing a flow of gas through one of the venturis toward the separator, thus creating a suction at the selected device to carry entrained matter through the respective debris conducting line to the separator. Distributing means are provided for diverting a minor portion of the gas flow to each of the other venturis to create a minor suction at the other devices to prevent unfiltered gas within the separator from escaping through the other debris conducting line.
