ABSTRACT:
The present invention relates to a multi-valve damper which divides a section of an airflow duct into at least two airflow sections. The damper has a plug body having a proximal end and a distal end. The plug body is adapted to separate a section of an airflow duct into at least two airflow sections. At least two damper blades may be mounted on the distal end of the plug body, each of the damper blades controlling airflow in a respective airflow section. At least one airflow sensor may be provided in each of the airflow sections for controlling the respective damper blades. An actuator mechanism responsive to the sensors may be provided for opening and closing the damper blades.
