PROBLEM TO BE SOLVED: To obtain a unit composite damper which can achieve the cost down, the space saving, and the simplification of control, by omitting an overlapping drive motor or controller. SOLUTION: This unit composite damper is equipped with a drive module 3 where both ends of the drive shaft of a drive motor 7 installed within are surfaced to outside and both ends of the surfaced drive shaft 9 are provided with shaft coupling means 13; and a damper module 5 where a plurality of sub chambers 21 having duct connection ports 23 are connected to one main chamber 19 having a duct connection port 23 and each communication part 25 between the main chamber 19 and the sub chamber 21 is provided with a damper plate 27 set at a specified angle, both ends of the fixed damper shaft 29 of this damper plate 27 are surfaced to outside, and both ends of the surfaced damper shaft 29 are provided with shaft coupling means 13. The plural damper modules 5 can be coupled freely to one drive module 3 via the shaft coupling means 13.
