In one embodiment, the present invention provides a high performance molded, substantially non-metallic fan capable of producing at least about 20 cubic feet per minute ("CFM") per input watt at a static pressure of about 0.00 inches of water. In one embodiment, the fan combines a substantially non-metallic housing, an airfoil cross-sectional fan blade, and a non-metallic hub. The fan blades may be detachable from the hub and rotationally indexable to a variety of pitch angles. Further, the hub and fan blades may include alignment indicia, so that the fan blades can be adjusted to a commensurate pitch relative of other fan blades around the hub.
