Check that the opening is free to expand and contract and that it matches the dial, and zero the dial when there is no problem. When connecting the pipe, connect the two sections of pipe to each side of the damper. Check that they are secure.
Our dampers are equipped with a scale, which you can adjust to adjust the flow of air in the pipe. Our dampers can be adjusted with an adjustable lever to control the size of the centre opening and thus the amount of ventilation.
Dampers can be used wherever there is pipe, so they can be used in many places, including airports, museums, concert halls, and other places where airflow needs to be controlled.
