Process and apparatus for treating an exhaust stream from a dental operatory

摘要

There is disclosed a process and apparatus for withdrawing an exhaust stream including gas, liquids and solids from the dental operatory connected to the suction side of a vacuum pump wherein solids and liquids are sequentially removed such that compressed gas from the vacuum pump is passed through a heat exchanger for cooling, thus permitting the use of lightweight, less expensive conduit piping for a vent exhaust conduit.
