Schematic illustration of JZ-S

① Casing

② Opposed blades

③ External linkage

④ Actuator

⑤ Transverse link

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 various speeds as the linkage includes a transverse link. This facilitates the closing process and reduces the air leakage in closed multileaf dampers.

The torques for operating multileaf dampers must be dimensioned in such a way 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 the impact of aerodynamic forces. When air flows through the damper, the aerodynamic forces of the airflow create a closing force (torque) on the blades; this happens independently of the direction of the airflow. This closing force must be countered, or overcome. The blade angle α with the largest torque depends, among other things, on the fan characteristics.

Quick sizing tables provide a good overview of the expected sound power levels and differential pressures. Approximate intermediate values can be interpolated. Precise intermediate values and spectral data can be calculated with our Easy Product Finder design program. The LWA sound power levels apply to multileaf dampers with a cross-sectional area (B × H) of 1 m². The differential pressures apply to multileaf dampers installed in ducts (installation type A).
