    Wide operating temperature range

    TUNE-AHU multi-blade dampers have a wide operating temperature from -20°C to 100°C in the duct and 50°C on the actuator.


    Maintenance-free

    TUNE-AHU dampers do not require regular maintenance once installed as part of air handling units and fan systems. 


    TUNE AHU rectangular multi-blade dampers are intended for use as part of air handling units and fan systems to cover the airflow adjustment and shut-off function. Available in different sizes, they can be used in indoor and conditionally outdoor climate conditions when installed on the body of a fan or in the rectangular duct section. They are equipped with a spring return electric actuator close in the event of power being interrupted. Manual operation and adjustment are also possible. They can operate in both directions of airflow. 

    TUNE-AHU dampers are mounted on AHU, FAN, or in ductwork by a 20mm flange connection. The damper can be installed in any spatial orientation. The multi-blade dampers have a wide operating temperature from -20°C to 100°C in the duct and 50°C on the actuator. TUNE-AHU-SE are manufactured from galvanized sheet steel, flange, and casing. The opposed action blades are extruded aluminium profiles and are equipped with a rubber gasket, eliminating air leakage in the closed position.
