 Manual and automatic damper

Manual air dampers are a device to stop or adjust the air flow in the ducts. The damper may be placed on the main line of the air duct, or it may be placed on any side line of the room to room between the channels to block the air entering the room that is not in use. or adjust the incoming air (hot or cold air) to each room. Dampers between manual channels are adjusted in two ways, manual and automatic. Manual dampers are adjusted by the damper handle that is installed on the outer space of the damper.
