Abstract
A separator for dental aspiration apparatus comprises a drainage pump and a suction pump activated by two respective electric motors. Fluid coming from a patient's mouth during an operation comprises a liquid part and a gaseous part which must be separated from the liquid part before the liquid part is discharged. The fluid to be separated is introduced into the drainage pump. The liquid part is discharged through an outlet of the drainage pump, while the gaseous part is aspirated back by the suction pump and then evacuated through an outlet. A control and command unit comprises a timer, of known type, which is able to command start-up of the motor of the suction pump after a predetermined time lapse after startup of the motor of the drainage pump.
