Versatile in Performance and Function

Belimo non fail-safe damper actuators are designed for use in a wide variety of HVAC damper applications. With our comprehensive torque range from 18 in-lbs to 1400 in-lbs and the ability to direct mount on standard damper shafts or jackshafts, these solutions are ideal for controlling dampers found in built-up or packaged air handlers, VAV terminal units, fan coil units, and unit ventilators used in hospitals, schools/universities, and data centers.

Increased Efficiency

Accuracy and Controllability

The Belimo non fail-safe return damper actuators use brushless DC motor technology, which is controlled by an Application Specific Integrated Circuit (ASIC) guaranteeing minimum torque over the entire operating range with no loss in performance due to temperature, supply voltage or speed.
