Belimo Non Fail-safe Damper Actuators Types

In this article, we are going to discuss the Belimo non-fail-safe damper actuator series and types.

Belimo Actuators


Non Fail-Safe Actuators:

Belimo non fail-safe damper actuators are designed for use in a wide variety of HVAC damper applications.

The torque range from 2 Nm to 160 Nm 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 center’s.
