Circular VAV Device

The Circular VAV Device is used in circular ducts to control air flow, especially in projects with special requirements such as comfort and hygiene. This system offers an important solution in terms of energy efficiency by saving up to 50% of the energy consumed by the fan motor. The air flow rate can be adjusted between minimum and maximum settings with a room controller with 0-10 V or 2-10 VDC analog signal. The products are calibrated according to the nominal flow rate values before shipment and sent to the customer. Duct connection with airtight rubber gaskets ensures tightness. Manufactured in accordance with EN 1946/4 and VDI 6022 hygiene standards, this device is suitable for use in both supply and exhaust lines. It withstands up to 1000 Pa pressure and operates effectively at air velocities between 28 m³/h and 5372 m³/h at ambient temperatures of 0-50°C and 95% relative humidity without condensation.
