Round CAV Constant Volume Controller Double-Walled Diameter 250 mm

The round CAV constant volume controller is designed to maintain a fixed airflow in duct-based ventilation systems. This double-walled model is used in installations where a constant air volume is required and where additional emphasis is placed on noise reduction and thermal insulation. The volume controller operates mechanically and automatically regulates the airflow, independent of pressure fluctuations in the duct system and 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 controls, increasing operational reliability.
• Integrated flow setting allows the desired air volume to be easily adjusted on site.
• Double-walled, insulated housing reduces noise emission and heat loss, contributing to a more comfortable indoor climate.

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 with varying pressure conditions in the duct. The double-walled design contributes to quieter operation and a uniform, predictable air distribution in practice.

Installation, Maintenance and Applications

The controller is installed directly into the round air duct and can be mounted horizontally or vertically. For proper operation, a straight duct section upstream of the controller is required to ensure an even airflow through the device. The housing is made of galvanized steel and equipped with seals for an airtight connection. Thanks to its simple mechanical construction, the volume controller is low maintenance and suitable for long-term use without periodic recalibration. This round CAV constant volume controller in a double-walled version offers a practical solution for ventilation systems where a fixed and reliable airflow is combined with increased comfort.
