Abstract
A damper assembly for use with an axial fan to prevent air from entering the discharge side of the fan when the fan is at idle. The damper assembly includes a damper door having multiple sections. The sections are able to pivot independently in response to the air flow created by the fan to minimize airflow resistance when the fan is operating.
