Round CAV Constant Volume Controller Double-Walled Diameter 125 mm

The round CAV constant volume controller is designed to maintain a fixed airflow in duct-bound ventilation systems. This double-walled version is used in installations where a constant air volume is required and where extra attention is needed for noise reduction and thermal insulation. The volume controller operates mechanically and regulates the airflow automatically, independent of pressure fluctuations within the duct system and without control by 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 operational 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 Application

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

Installation, Maintenance and Applications

The controller is mounted directly in the round duct and can be installed both horizontally and vertically. For correct operation, a straight duct section before the controller is necessary to ensure uniform airflow through the controller. The casing is made of galvanized steel and equipped with seals for an airtight connection. Due to its simple mechanical design, the volume controller requires minimal maintenance and is suitable for long-term use without periodic adjustment. This round CAV constant volume controller in double-walled design provides a practical solution for ventilation systems where a fixed and reliable airflow is combined with enhanced comfort.
