Leakage: The amount of air passing through a damper with a given pressure drop and a given torque holding the damper closed. Thus, in a partially closed position, a forced vortex with the same rotational direction as the fan impeller will be generated within the inlet box. Electric motors, air cylinders, and oil cylinders are able to actuate louver dampers with little difficulty. It then gives a signal tomatches the input signal.
