Abstract
An axial fan comprising a hub and a plurality of blades extending from a periphery of the hub. Each of the blades has a thickness which varies from a leading edge to a trailing edge and from a root to a tip. The blades are unevenly spaced around the periphery of the hub in a pattern which is not balanced. The fan is balanced by variance in blade thickness among the plurality of blades.
