Tunnel dampers with a linkage have same or opposed action. An external linkage transfers the synchronous rotational movement from the drive arm to the individual blades. Even large dampers can be safely opened and closed with this type of linkage. Opposed action blades close at different angular velocities due to the transverse link. As a result, the closing properties are better and the air leakage is low when the damper is closed.
Nominal sizes | 357 × 345 – 2000 × 1998 mm |
Volume flow rate range | 200 – 40,000 l/s or 720 – 143,640 m³/h |
Maximum static differential pressure | Up to 3000 Pa |
Operating temperature | -20 – 150 °C in normal operation, 400 °C, 120 min in the event of a fire |
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.
