1 Differential pressure sensor
2 Damper blade
3 Gear
4 Control components, e.g. Easy controller

The VAV terminal unit is fitted with an effective pressure sensor for measuring the volume flow rate.
The control components (attachments) include an effective pressure transducer that transforms the effective pressure into an electric signal, a controller, and an actuator; the control functions can be achieved with an Easy controller or with a Compact controller or with individual components (Universal or LABCONTROL).
For most applications, the setpoint value comes from a room temperature controller.
The controller compares the actual value with the setpoint value and alters the control signal of the actuator if there is a difference between the two values.

Nominal sizes

200 × 100 – 1000 × 1000 mm

Volume flow rate range

42 – 17,223 l/s or 149 – 62,005 m³/h

Volume flow rate control range (unit with dynamic differential

pressure measurement)

approx. 20 to 100 % of the nominal volume flow rate

Minimum differential pressure

Up to 109 Pa (without secondary silencer)

Maximum differential pressure

1000 Pa

Operating temperature

10 to 50 °C
