Our Volume Control Dampers have numerous features designed to give maximum performance. We use an aerofoil blade, shaped to provide exceptionally low resistance to air travelling over it.
The standard out of airstream linkage is also fitted, protecting the precise gears from dust and moisture. This linkage system uses nylon gears and wearing parts, coming together to produce a damper with exceptionally low operating torque. Not only does this make it easier for you to adjust your damper manually, but, if motorised, it means dramatically reduced loading on actuators and therefore an extended working life
