Maintenance
Multileaf dampers with gears can only have opposed action blades.
The internal gears transfer the synchronous rotational movement from the drive arm to the individual blades.
The torque for actuating multileaf dampers must be dimensioned so 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 sound power levels and differential pressures that can be expected. Approximate intermediate values can be interpolated. Precise intermediate values and spectral data can be calculated with our Easy Product Finder design program.
The sound power levels LWA 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).
