VAV Box Unit

The VAV Box Unit is designed for variable air volume systems and duct pressure control applications. Its ability to calibrate with high precision between 150 and 5000 m³/h makes this unit suitable for various airflow requirements. Galvanized or stainless steel material options are available for production, providing durability and flexibility for different operating conditions. Equipped with an average differential pressure sensor for air flow measurement, this unit also includes a control damper and integrated silencer, which reduces airborne noise and increases system efficiency.
