Round CAV Constant volume controller single wall diameter 250 mm

Round CAV Constant Volume Controller Single-Walled Diameter 250 mm

The round CAV constant volume controller is specifically designed to maintain a fixed air volume flow in ducted ventilation systems. This single-walled version is used in installations where a constant airflow is required, regardless of pressure fluctuations in the duct system. The volume controller operates mechanically and automatically regulates the air flow without the need for control by 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.
• 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 preset 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 is required upstream of the controller to ensure an even airflow through the device. The housing is made of galvanized steel and equipped with seals for an airtight connection. Due 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-walled construction offers a practical solution for ventilation systems that require a fixed and reliable airflow.
