There are different ways to branch out from the air transfer channels, such as taking off, but in places where there is space limitation, using an air damper is an easy and logical way to connect the valves to the air transfer channels, which allows the control of the outgoing air flow. slow
The air damper has a crescent-shaped vane the size of the opening on the channel, which, by opening against the direction of the air flow in the channel, directs the air towards the opening. The more the crescent shaped vane of the damper is opened, the more air is directed from the main path; This value can be controlled by the damper handle mounted on the main shaft axis. It is possible that by installing the damper motor on the shaft, the volumetric control of the air intake can be done dynamically and without access to the damper.
