Damper Drives

Pneumatic and Electric Floor Mounted Damper Drives

  • Pneumatic Damper Drives up to 35,000 in.-lbs. torque
  • Electric Damper Drives up to 26,000 in.-lbs. torque

Triac floor mounted damper drives are the best choice for operating dampers, vanes and fan control where high vibration, heat, extreme cold, dust and inaccessibilty render direct coupling of actuators to shafts impractical.

Available in pneumatic (on-off and modulating), and electric (24 VDC, 120 VAC 1-phase, 220 and 440 volt 3-phase configurations, these rugged drives combine industry proven Triac pneumatic and electric actuators with our engineering expertise.

The rugged frames can be ordered to dimensionally replace older drives manufactured by several previous suppliers. Triac frames consist of welded steel housings with pillow block bearings, maintenance access panels, and our unique infinite position lever arms. The units are tough enough for the harshest environments found in today’s refineries, power plants, steel-making boiler rooms, water treatment facilities, pollution controls, pulp and paper industries and co-generation turbine units.
