An air diffuser with a series of parallel blades has an air deflector structure for reducing throw and promoting better air mixing near the diffuser, having support members diverging transversely from one another laterally outwardly. Each support member has a series of vanes that diverge transversely laterally outwardly and extend through inner and outer regions adjacent or between the blades. A vane may have a forwardly extending barb having a sharp apex projecting into a recess forwardly of an outer rear edge of a forwardly adjacent vane, for biting engagement with a blade, and the same or another vane may have an undercut portion projecting outwardly rearwardly beyond an inner edge portion of a rearwardly adjacent vane, for engaging under a blade for firmly locating the deflector structure relative to the blades.
