Model V750 – C: Constant Volume

CONNOLS-AIR DDC microprocessor based V750 air terminal units are the latest, state-of-the-art, high quality terminal units, that provide good control accuracy and capabilities required in every modern intelligent building. The air terminal units are capable of stand-alone operation, however, optimum functional benefits are derived when network communication capabilities are used.

Each air terminal unit consists of an air damper with an integrated pressure differential multiple point airflow sensor, a digital thermostat and a BACnetTM compliant DDC controller. The damper is constructed of galvanized steel circular double-skin casing with 25 mm fiber glass-filled annular space. Damper blade is constructed of double-skin steel plate with solid silicon all round that provides an excellent seal when closed.

The X-Sensor (Cross sensor) is a true averaging pressure differential sensor with amplification of 2 and is able to accurately measure airflow to turndown of 2 m/s. The performance of V750 X-Sensor and damper is AMCA certified to accuracy of 3.7% or better in the velocity range of 4 to 13 m/s.
