An air distribution chamber that allows selective distribution of air to a variety of vents or combinations thereof is provided. The distribution chamber comprises a nested pair of chambers that define a central cavity having an open and closed end, a shaft that allows axial and rotational movement of the inner chamber within the outer chamber, an actuator that controls such movement, a stabilizer for maintaining the open end and receiving the shaft, and a seal between the inner and outer chambers. The outer chamber defines a series of flanged openings, and the inner chamber defines a series of apertures. The flanged openings are of a form that allows connection of the distribution chamber to ducts. When the inner and outer chambers are aligned such that the openings and apertures overlap, defining one or more communicative passageways, air is able to escape from the cavity, through the aperture and opening, and into the duct. By responding to mode selection by a user, the actuator moves the inner chamber such that appropriate alignments are made, and the selected mode of air distribution is achieved.
