Round CAV Constant Volume Controller Double-Walled Diameter 200 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 where a constant air volume is required and where additional attention is needed for noise reduction and thermal insulation. The volume controller operates mechanically and automatically regulates the airflow independently of pressure fluctuations in the duct system, without requiring control from a building management system or external power supply.

Advantages and Features

• Constant volume control keeps the set airflow stable despite changing duct pressures within the ventilation system.
• Mechanical operation eliminates the need for external power or communication controls, enhancing operational reliability.
• Integrated flow adjustment allows the desired air volume to be easily set on site.
• 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 engineered for stable operation within the pre-set airflow range. Once set, the airflow remains constant even under varying pressure conditions within the duct. The double-walled design contributes to quieter operation and ensures even, predictable air distribution in practice.

Installation, Maintenance and Applications

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