Abstract
A separator for a suction air-solid-liquid mixture in a dental suction apparatus has an intermediate container situated beneath an air separation chamber, which has an outlet for the separated mixture. Associated with and situated along side the mixture outlet, a separation device for the solids has a removable sedimentation basin and a clean liquid outlet through which the clean liquid is conveyed into the intermediate container. A tube connecting with the second segment of the suction line passes through the intermediate container from the air separation chamber and has a clean liquid admission port so that the solids-free liquid is fed back into the suction air.
