The pre-swirler includes an array of spaced apart vanes extending radially outwardly from a central hub. The vanes extend from the hub to an outer ring that is attached to the housing of the blower assembly. The vanes are configured to cooperate with the blower wheel to minimize a noise, a vibration, and a harshness (noise, vibration, harshness (NVH)) of the blower assembly, while maximizing an efficiency thereof. |
