Functional description

Multileaf dampers with external linkage can have parallel action blades or opposed action blades.

An external linkage transfers the synchronous rotational movement from the drive arm to the individual blades. Even very large multileaf dampers can be safely opened and closed with this type of linkage.

Opposed action blades close at different speeds since the linkage includes a transverse link. This facilitates the closing process and reduces the closed blade air leakage.

The torque for closing a multileaf damper must be such that the damper can be safely opened and closed.

For closure, the torque must suffice to ensure complete shut-off by the blades.

Opening is initiated without aerodynamic forces.

When air flows through the damper, the aerodynamic forces of the airflow create a closing force (torque) on the blades; this happens independent of the direction of the airflow. This closing force must be countered, or overcome. The blade position, or blade angle α, for which there is the largest torque depends, among other factors, on the fan characteristics.
