Abstract: A portable self-contained air distribution unit, and system incorporating same, are useful in assisting in the distribution of air within a vehicle. The unit comprises an elongate conduit having an inlet, an outlet and a top portion spaced from a bottom portion. A chamber is within the elongate conduit in airflow communication with the inlet and the outlet. A front flap is joined to the inlet of the conduit. The front flap is moveable between an open position and a retracted position and when the front flap is in the open position air flows into the inlet through the chamber and exits the at least one outlet. Various additional features may be combined as desired.
