A first vertical tube is connected to an upper air supply conduit and extends downwardly and opens rearwardly near the front of the unit to direct air towards the door structure outlet. A second vertical tube which extends downwardly near the rear of the unit and opens towards the outlet is connected to the air supply conduit to direct a sweeping blast of air towards the outlet near the floor of the door structure where plugging is a problem.
