Back to Regulation

The WM-10 Series dampers are aluminium volume control dampers for rectangular duct with horizontal counter-rotating blades. They find their application in control, regulation, balancing and calibrationof the air distribution net. The movement transmission if obtained thanks to two gear trains
while the blades profile allows a good holding characteristic in total closing.
