Abstract
An air moving device assembly in a computer system has an air moving device such as a fan or blower within a housing for moving air from an air inlet to an air outlet. A mesh with a plurality of openings covers the air outlet. A back flow damper assembly is positioned over the air outlet. The back flow damper assembly further comprises at least one damper door movable in an open position and a closed position. The damper door has at least one tooth such that when the damper door is in the closed position, the tooth interacts with at least one of the plurality of openings in the mesh. By periodically cycling the air moving device controlled by device management software, the teeth will close and open, loosening debris from the mesh, allowing the debris to be blown out the rear of the housing once the device is turned back on.
