Round CAV Constant volume control single wall diameter 200 mm

Round CAV Constant Volume Controller Single-Walled Diameter 200 mm

The round CAV constant volume controller is specifically designed to maintain a fixed airflow rate in duct-based ventilation systems. You apply this single-walled version 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 control from 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 setting allows easy on-site adjustment of the desired air volume.
• Single-walled housing provides a compact and practical solution for applications where sound or thermal insulation is not required.

Performance and Usage

The CAV volume controller is designed for stable operation within the pre-set airflow range. Once set, the air volume remains constant even under fluctuating 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 proper functioning, a straight duct section upstream of the controller is required to ensure uniform airflow through the controller. The housing is made of galvanized steel and equipped with seals for an airtight connection. Due to its simple mechanical design, the volume controller is low-maintenance and suitable for long-term use without periodic adjustment. This round CAV constant volume controller in single-walled design offers a practical solution for ventilation systems that require a fixed and reliable airflow rate.
