TUNE-AHU-SE011-400x200-TF24

The TUNE-AHU-SE, rectangular multi - blade dampers are mainly intended as a part of air handling units and fan systems to cover the air flow tuning and tight shut-off functionalities. The dampers can be used in indoor and outdoor climate conditions installed on the body of a fan or in the rectangular duct. They are equipped by electric actuator with spring return to closed position in case of electric power interruption. Manual operation/adjustment is also possible. They can operate in both directions of air flow. The air tightness of the dampers is classified as C3 according to the standard EN 1751 in pressure range up to 1000 Pa which is the maximum recommended duct pressure for this product. The operation temperature range is -20°C ... 100°C in duct, 50°C on actuator.

TUNE-AHU-SE are manufactured with galvanized steel flanged casing. The opposed action blades from extruded aluminium profile are equipped by rubber gasket eliminating leakage in closed position. The blade shafts are sitting in self-lubricating polymeric bearings. The connection to the ductwork is secured by 20 mm wide flanges.
