<p>The invention is directed to an air flow controllable register for controlling a flow of air through the register from a register airflow supply duct (18) in response to an externally provided control signal that commands differing airflow rates through the register. More specifically, the airflow controllable register includes a register flow control unit that includes a rotary mounted fan (80) positioned within the register airflow supply duct. The fan is coupled to a motor. The fan when driven by the energized motor creates air pressure from the fan to reduce the flow of air from the supply duct.</p> |
