A-T Controls TRIAC® Floor Mounted Pneumatic Damper Drives

TRIAC floor mounted damper drives are for operating dampers, vanes and fan control where direct coupling of actuators to shafts is difficult due to high vibration, heat, extreme cold, dust and inaccessibility.

Their rugged frame construction includes a welded steel housing with pillow block bearings, maintenance access panel, and a unique infinite position lever arm.

TRIAC damper drives withstand harsh environments in refineries, power plants, steel-making boiler rooms, water treatment facilities, pollution controls, pulp and paper industries, and cogeneration turbine units.
