WM-05 series volume control dampers are aluminium volume control dampers for rectangular ducts with horizontal blades.

They find their application in the control, regulation, balancing and calibration of air distribution networks. The transmission of movement is achieved by means of a gear train, while the profile of the blades allows a good sealing characteristic in total closure.
