Abstract
In one embodiment, a filter cleaning system and method pertain to, during a filter cleaning operation, reversing a flow direction of an inlet fan associated with a filter of the electrical device, the inlet fan being adapted to force air into a housing of the electrical device during normal operation of the electrical device, and reversing a flow direction of an outlet fan adapted to draw air out from the electrical device housing during normal operation of the electrical device so as to increase pressure within the electrical device housing during the filter cleaning operation, wherein the combined action of the reversed inlet fan and the reversed outlet fan purges particulate matter from the filter.
