Round CAV Constant Volume Controller Single-Wall Diameter 315 mm

The round CAV constant volume controller is specifically designed to maintain a fixed airflow rate in ducted ventilation systems. This single-wall version is used in installations where a constant air volume is required regardless of pressure fluctuations within the duct system. The volume controller operates mechanically, automatically regulating the airflow without the need for control by a building management system or external power supply.

Benefits and Features

• Constant volume control keeps the set airflow rate stable despite changing duct pressures within the ventilation system.
• Mechanical operation eliminates the need for external power or communication control, enhancing reliability.
• Integrated flow adjustment allows for easy on-site configuration of the desired air volume.
• Single-wall casing provides a compact and functional solution for applications where no acoustic or thermal insulation is required.

Performance and Application

The CAV volume controller is designed for stable operation within the preset airflow range. Once set, the airflow remains constant even with varying pressure conditions in the ductwork. This contributes to predictable air distribution and a reliably functioning ventilation system.

Installation, Maintenance and Applications

The controller is mounted directly into the round air duct and can be installed both horizontally and vertically. For correct operation, a straight duct section is required upstream of the controller to ensure uniform airflow through the device. The casing is made from galvanized steel and fitted with seals for an airtight connection. Thanks 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 single-wall design provides a practical solution for ventilation systems requiring a fixed and reliable airflow.
