Round CAV Constant Volume Controller Double-Walled Diameter 100 mm

The round CAV constant volume controller is designed to maintain a fixed airflow rate in duct-based ventilation systems. This double-walled model 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, regulating the airflow automatically, 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 maintains 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 setting allows easy on-site adjustment 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 engineered for stable operation within the pre-set airflow range. Once set, the airflow remains constant even under varying pressure conditions in the duct. The double-walled design contributes to quieter operation and ensures 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 required to ensure even airflow through the device. The casing is made from galvanized steel and fitted with seals for an airtight connection. Thanks to its simple mechanical construction, the volume controller is low-maintenance and 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 requiring a fixed and reliable air volume combined with enhanced comfort.
