Abstract
A packaged terminal air conditioner unit (PTAC) includes a vent aperture defined in a bulkhead of the PTAC and a fan assembly for urging a flow of make-up air through the vent aperture. The fan assembly includes a fan duct fluidly coupled to the bulkhead over the vent aperture, the fan duct defining an inlet that extends away from the bulkhead toward a rear of the PTAC. An auxiliary fan is mounted to the fan duct for urging the flow of make-up air through the vent aperture, the auxiliary fan including a plurality of fan blades and a stabilizer ring extending about the circumferential direction between the plurality of fan blades.
