TUNE-R-630-3-NF24A

Art. no.: 79893

Description

The TUNE-R, circular single-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 TUNE-R or fan or in the circular 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 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.

Design

TUNE-R dampers are constructed from galvanized steel sheet. The blade is equipped by rubber gasket eliminating leakage in closed position. The blade shaft is sitting in self - lubricating polymeric bearings.

The connection of to the ductwork is sealed by rubber gaskets contributing to the casing tightness.
