① Double lip seal
② Casing
③ Damper blade including effective pressure sensor
④ Shaft with effective pressure channel
⑤ Electronic volume flow controller
The control damper blade works as an actuator and as an effective pressure sensor. Through the effective pressure channel in the shaft of the detected effective pressure reaches the transducer (static or dynamic), is converted into an electrical signal and compared with the setpoint value.
In the case of a control deviation, the integrated actuator changes the position of the control damper blade. As a result, the volume flow rate is kept constant in close tolerances over the entire differential pressure range.
Nominal sizes | 100 – 250 mm |
Volume flow rate range | 4 – 637 l/s or 14 – 2293 m³/h |
Volume flow rate control range (unit with dynamic effective pressure measurement) | Approx. 4 to 100 % of the nominal volume flow rate |
Minimum differential pressure | <5 – 82 Pa |
Maximum differential pressure | Control component with dynamic transducer: 900 Pa, Control component with static transducer: 600 Pa |
Operating temperature | 10 to 50 °C |
Quick sizing tables provide a good overview of the room sound pressure levels 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 programme.
The first selection criteria for the nominal size are the actual volume flow rates qvmin and qvmax. The quick sizing tables are based on generally accepted attenuation levels. If the sound pressure level exceeds the required level, a larger air terminal unit and/or a silencer is required.

Upstream conditions
The effective pressure, which is decisive for the volume flow rate, is recorded and averaged on the control damper blade. Therefore, the volume flow rate accuracy Δqv is independent of the upstream section.
Duct connections, e.g. branches off the main duct, must comply with EN 1506 and EN 13180.
