TUNE-S is a control and shut-off damper designed for rectangular ducts. It consists of a frame made from sheet steel and aluminium profile blades. The frame has 20mm wide flanges. It is available with blade tightness class C4, tested according to EN 1751. It is ideal for use as a control and shut-off damper where different parts of the system need to be airtight and separated from each other.
Available in different sizes, the damper can be supplied in both manual or motorised versions. It can be used on air handling units as an outer shut-off damper or with a modulating actuator as a control damper. The maximum recommended duct pressure is 1000 Pa. The aerofoil blades are equipped with rubber gaskets that minimize leakage when in closed positions. The blade axe sits in self-lubricating bearings which can be connected together by a cog-rod combination. This ensures a smooth ratio and transition from blade to blade.
