Abstract
An air delivery system includes a visor having an outer peripheral edge and an inner peripheral edge. An air filtration assembly is removably mounted above an opening in the visor between the outer and inner peripheral edges, the air filtration assembly comprising a fan having an air inlet and an air outlet, an anode layer disposed over the air inlet, a filter layer disposed over the anode layer and a cathode layer disposed over the filter layer. In a first configuration, the air filtration assembly provides air flow toward an inner surface of the visor and, in a second configuration, the air filtration assembly provides air flow away from an outer surface of the visor. The air filtration assembly includes a mode actuator configured to control operation of a filtration mode indicator in dependence upon positioning of the air filtration assembly in the first or second configuration.
