TUNE-AHU-DE007-042-588x588-M0

The TUNE-AHU-SE, are rectangular multi - blade dampers intended as a part of air handling units and fan systems to cover the air flow adjustment and shut-off function. The dampers can be used in indoor and outdoor climate conditions installed on the body of a fan or in the rectangular duct section.

They are equipped with a spring return electric actuator which close on power interruption.

Manual operation and adjustment is also possible. They can operate in both directions of air flow. The air tightness of the dampers is classified as C4 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 from galvanized sheet steel, flange and casing. The opposed action blades are extruded aluminum profiles and are equipped by rubber gasket, eliminating air 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.

TUNE-AHU-SE is mounted on AHU, FAN or in ductwork by a 20 mm flange connection. The damper cannot be installed carrying any mechanical loads from other structures. The damper can be installed in any spatial orientation.

Maintenance: maintenance-free.

Operating temperature range: -20°C ... 100°C in duct, 50°C on actuator.
