Round CAV Constant volume controller single wall diameter 160 mm

Round CAV Constant Volume Controller Single-Walled Diameter 160 mm

The round CAV constant volume controller is specifically designed to maintain a fixed airflow rate in ducted ventilation systems. This single-walled 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 and automatically regulates the airflow without the need for control by a building management system or external power supply.

Advantages and Features

• Constant volume control maintains the set airflow rate 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.
• Single-walled casing provides a compact and functional solution for applications where no sound or thermal insulation is necessary.

Performance and Usage

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

Installation, Maintenance and Applications

The controller is mounted directly in 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 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 construction, the volume controller requires minimal maintenance and is suitable for long-term use without periodic adjustment. This round CAV constant volume controller in a single-walled design provides a practical solution for ventilation systems requiring a fixed and reliable airflow.
