Round CAV Constant Volume Controller Double-Walled Diameter 160 mm

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

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