Abstract
Combined air duct apparatus and silencer for attachment to both the inlet and the outlet of a fan unit for a building wherein each silencing apparatus has an exterior housing with an air inlet and an air outlet, one of which is adapted for connection to the fan unit. The inlet and outlet are connected by an airflow passageway defined by interior walls of the housing. First and second series of splitters are also provided in the outlet duct unit. The splitters in each series are spaced apart to form smaller air passageways and mounted side-by-side in a row. In the outlet duct unit, the air inlet is circular or annular while the outlet is rectangular. In one embodiment, the outlet lies in a plane at a substantial angle to the plane of the annular inlet and the main airflow passageway is substantially curved in its lengthwise direction.
