ABSTRACT:
An air handling duct system is provided wherein downstream duct segments are downsized proportionately relative to a immediate upstream duct segments including lateral outlets in order to maintain design air volumes in the upstream and downstream duct segments, wherein downstream duct legs of angular turns are proportionately up sized relative to upstream duct legs of the angular turns in order to prevent increases in flow resistance in the duct system as a result of the turns and wherein lateral branch duct runs are proportionately sized relative to established air flow volumes immediately upstream from said branch ducts and the flow volumes in the upstream ends of said branch duct runs.
