An air vent is provided that is capable of delivering a distributed divergent air flow with a predominant direction of flow that can be changed within a wide range of mutually perpendicular directions. In one embodiment, the air vent has an outlet grid that is generally ball shaped and that is rotatably mounted at an end of an air duct for rotation about its center. Each of the multiple outlet openings of the grid points to a direction that is different from pointing directions of all other outlet openings so that a divergent air flow is obtained. By rotating the ball shaped grid about its center, the predominant direction of air flow can nevertheless be changed in a within a wide range.
