Abstract: A housing receives ambient air through an inlet located so as to direct the airflow against blades of a rotor which disperses the airflow. A gas inlet conduit discharges hazardous gas into a chamber of the housing. The dispersed airflow acts on the hazardous gas entering the chamber to disperse and mix with the gas. The mixed air and hazardous gas flow impinges against a wall surface of the housing prior to discharge from the housing via an outlet conduit. A source such as the intake side of a blower induces the flow of air and hazardous gas through the housing and the outlet conduit. The rotor is located near an air inlet of the housing for rotor operation by airflow drawn into the housing. A flow sensor and damper control system are provided.
