Round CAV Constant Volume Controller Single-Walled Diameter 125 mm

The round CAV constant volume controller is specifically designed to maintain a fixed airflow in duct-bound ventilation systems. This single-walled model is used in installations where a constant airflow is required, regardless of pressure fluctuations within the duct system. The volume controller operates mechanically and regulates the airflow automatically, without control from a building management system or external power supply.

Advantages and Features

Constant volume control keeps 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 adjustment allows easy on-site setting of the desired air volume.
Single-walled casing offers a compact and functional solution for applications where no sound or thermal insulation is 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 under varying pressure conditions in the duct. This ensures predictable air distribution and a reliably functioning ventilation system.

Installation, Maintenance and Applications

The controller is mounted directly within the round air duct and can be installed horizontally or vertically. For correct operation, a straight duct section before the controller is necessary to ensure even airflow through the controller. The casing is made of galvanized steel and equipped with seals for an airtight connection. Thanks to its simple mechanical design, the volume controller is low-maintenance and suitable for long-term use without periodic adjustments. This round CAV constant volume controller in single-walled design provides a practical solution for ventilation systems requiring a fixed and reliable airflow.
