Gear Drive Dampers

Gear Drive Dampers weigh less and require less torque than certain others types of dampers, since they run on gears in order to open and close. These gears may be attached to a motor, which makes the system entirely automated. This is less work for personnel in industrial settings, since the job of opening large dampers is left up to machines.

A sensor that reads pressures and/or temperatures alerts the damper as to when and how it should adjust rather than relying on manual movement. They still require occasional checks, however, to ensure that they are working properly.
