Round CAV Constant Volume Controller Single-Wall Diameter 400 mm

The round CAV constant volume controller is specifically designed to maintain a fixed airflow in duct-bound 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 and automatically regulates the airflow without the need for building management system control or external power supply.

Benefits 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-wall housing provides a compact and functional solution for applications where sound or thermal insulation is not required.

Performance and Application

The CAV volume controller is designed for stable operation within the preset airflow range. Once set, the airflow remains constant even under varying pressure conditions in the duct, contributing 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 device. The housing 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 recalibration. This round CAV constant volume controller in a single-wall design offers a practical solution for ventilation systems requiring a fixed and reliable air volume.
