ABSTRACT:
A method and means for providing an improved air distribution for a plurality of rooms insuring that rooms further along the main duct line from the blower source are adequately provided with air. This is accomplished by providing a counterweighted closure for the ceiling plenum return outlet of each of a plurality of air control boxes. Each of said closures is counterweighted to provide a back pressure to the air in the main duct when the main damper of the air control box is closed, equivalent to the back pressure provided by the resistance to air flow through the control box, diffuser outlets of each control box and the static pressure present in the rooms supplied by the diffuser outlets when the main damper of the control box is open.
