Round CAV Constant Volume Controller Single-Wall Diameter 100 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 airflow 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, increasing operational reliability.
Integrated flow setting allows easy adjustment of the desired air volume on-site.
Single-wall casing provides a compact and functional solution for applications where acoustic or thermal insulation is not required.

Performance and Usage

The CAV volume controller is engineered for stable operation within the predefined airflow range. Once set, the airflow remains constant even under 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 into the round air duct and can be installed both horizontally and vertically. For proper operation, a straight duct section upstream of the controller is necessary to ensure uniform airflow through the device. The casing is made of galvanised steel and equipped with seals for an airtight connection. Thanks to its straightforward 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 offers a practical solution for ventilation systems requiring a fixed and reliable airflow.
