Maintenance
① Effective pressure sensor
② Damper blade with seal
③ Gears
④ Control components, e.g. an 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 × 600 mm |
Volume flow rate range | 42 – 8010 l/s or 149 – 28836 m³/h |
Volume flow rate control range (unit with dynamic effective pressure measurement) | approx. 20 to 100 % of the nominal volume flow rate |
Minimum differential pressure | up to 104 Pa (without secondary silencer) |
Maximum differential pressure | 1000 Pa |
Operating temperature | 10 to 50 °C |

Specification text
Rectangular VAV terminal units for variable and constant air volume systems, suitable for supply or extract air, available in 36 nominal sizes. High volume flow rate control accuracy. Ready-to-commission unit which consists of the mechanical parts and the electronic control components Each unit contains an averaging effective pressure sensor for volume flow rate measurement and damper blades. Factory mounted control components complete with wiring and tubing Effective pressure sensor with 3 mm measuring holes, hence resistant to contamination. Position of the damper blades indicated externally at the shaft extension. The damper blade is factory set to open position, which allows a ventilation airflow even without control; this does not apply to variants with defined safe position NC (normally closed).
