Air Volume Control | 3 / 8
Description
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 ow 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 ow. The air tightness of the dampers is classied 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.
Design
TUNE-AHU-SE are manufactured with galvanized steel anged casing. The opposed action blades from extruded
aluminium prole 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 anges.
