Round CAV Constant Volume Controller Double-Walled Diameter 315 mm

The round CAV constant volume controller is designed to maintain a fixed airflow rate in ducted ventilation systems. This double-walled version is used in installations requiring a constant air volume and where extra attention is needed for noise reduction and thermal insulation. The volume controller operates mechanically and automatically regulates the airflow, independent of pressure fluctuations within the duct system and without control from a building management system or external power supply.

Advantages and Features

• Constant volume control keeps the set airflow stable despite varying duct pressures within the ventilation system.
• Mechanical operation eliminates the need for external power or communication control, enhancing reliability.
• Integrated flow adjustment allows easy on-site setting of the desired air volume.
• Double-walled, insulated casing reduces noise emission and heat loss, contributing to a more comfortable indoor climate.

Performance and Usage

The CAV volume controller is designed for stable operation within the preset airflow range. Once set, the air volume remains constant even with varying duct pressure conditions. The double-walled design contributes to quieter operation and ensures an even, predictable air distribution in practice.

Installation, Maintenance and Applications

The controller mounts directly into the round air duct and can be installed horizontally or vertically. For proper functioning, a straight duct section upstream of the controller is necessary to ensure uniform airflow through the device. The casing is made of galvanized steel and equipped with seals for an airtight connection. Due to its simple mechanical construction, the volume controller is low-maintenance and suitable for long-term use without periodic recalibration. This round CAV constant volume controller in double-walled execution provides a practical solution for ventilation systems requiring a fixed and reliable airflow combined with enhanced comfort.
