Air flow regulator VAV

Automatic adjustment with precise readings (accuracy – 5% between 1-8 m/s). Flow rate shown in real time (in l/s or m3/h). Wide range of diameters. Easy to install and use. The motor can be positioned in any position. Factory pre-sets vor V.min & V.max. V.min & V.max pre-sets can be adjusted on-site, using a screwdriver. 0V signal used to fully close the damper. Single product for both air supply and exhaust. 2 models: Standard VAV and soundproofed VAV (double wall of 50 mm of insulation). Available diameters in mm: 100, 125, 160, 200, 250, 315, 400, 500 & 630. Airflow range: 50 to 9000 m3/h. Accuracy 5% for air speed > 1 m/s (15% below). Air speed: 1 – 8 m/s. Leak tightness – Class 3 upstream & downstream – Class B casing in accordance with EN 1751. Galvanised steel body and damper. Can use presence sensors, CO2 sensors or thermostats (set point 0 – 10 V or 2 – 10 V). GENERAL INFORMATION RANGE - The VAV is an Air Flow Regulator. It is used to control and adjust the air flow rate based upon a set point level, either on the air supply or air return side. It assures hygiene (ventilation) or the thermal comfort of occupants (air conditioning). FIELD OF APPLICATION • Variable flow rate adjustment based upon a set-point defined by a min. and max. value, calibrated in the factory and adjustable on-site after installation, if necessary. • Airflow regulation for CMEV or air-conditioning installations. • Can be used both for air supply and air return. • Airflow adjustment ranges (see opposite). RANGE • 2 models: - Standard VAV, - Insulated VAV. • 9 diameters (mm): 100, 125, 160, 200, 250, 315, 400, 500 & 630. • Airflow rates: 50 - 9000 m3/h. • Air speed: 1 - 8 m/s.
