A compact damper needs automatic intermediate positions.
The modulating drive follows an analogue command rather than only opening or closing.
Alternating aerofoil blades vary the opening within a shallow rectangular frame. An external linkage couples the blades to the side-mounted actuator, allowing an analogue signal to position the compact damper as ventilation demand changes.
