    Airflow adjustment & shut-off damper

    The TUNE-R for AHU devices act as both an air flow tuner and shut-off damper when installed into circular ducts. 


    Galvanised steel

    Tune-R dampers are constructed from galvanised steel sheet. The blade is equipped with a rubber gasket that eliminates leakage when closed. 


    Indoor/Outdoor use

    The dampers can be used effectively in indoor and conditionally in outdoor settings. 


    The TUNE-R for AHU devices is principally designed to be used as part of air handling units and fan systems to cover the airflow tuning and the airtight shut-off functionalities. The dampers can be used in indoor and conditionally in outdoor climates. They are equipped with an electric actuator that features a spring return to a closed position in the event of a power interruption. Manual operation and adjustment are also possible. 

    Available in different sizes, the dampers can operate in both directions of airflow. The air tightness of the dampers is classified as C4 according to the standard EN1751 in a pressure range up to a maximum of 1000 Pa. The product has an operating temperature range from -20°C  to 100°C when installed in a duct, or to 50°C on an actuator. TUNE-R dampers have a galvanised steel sheet construction. The blade is equipped with a rubber gasket that eliminates leakage when in a closed position. The blade shaft sits in self-lubricating polymeric bearings.
