Claim:
A static air mixing apparatus adapted for intermixing airstreams of different temperatures flowing through a common duct having walls defining a passageway, said apparatus comprising: a plurality of vanes mounted transversely in the duct with respect to a direction of the airstreams flowing therethrough, said plurality of vanes diverging away from a center of said duct and terminating at their outer distal ends adjacent to said duct, at least one vane of said plurality of vanes having an inner section traversing a first distance from the center, and an outer section connected to said inner section along a leading radial edge of said vane, said outer section traversing a remaining distance toward said duct, said inner section curving rearwardly in a first direction away from said leading radial edge, and said outer section curving rearwardly in a second direction away from said leading radial edge.
