Honeywell Commercial M9174B1027 Damper Actuator

Honeywell M9174B1027 Damper Actuator is a high-precision electric proportional damper actuator designed for commercial HVAC systems. This non-spring-return unit delivers reliable damper control with fast response, supported by UL and CE approvals.

Operate with 120 VAC at 50/60 Hz and 75 in-lb of torque to move dampers through a precise 90-degree, clockwise rotation in a 30–60 second window. This configuration makes it an ideal electric proportional damper actuator for accurate airflow modulation and energy efficiency in demanding environments.
