Honeywell Commercial M9174C1025 Damper Actuator

The Honeywell M9174C1025 Damper Actuator is a high-precision electric proportional damper actuator designed for commercial HVAC systems. This model features non-spring return operation and a 120 VAC supply, delivering smooth, modulated damper positioning across a 90-degree rotation. UL and CE approvals confirm its robust performance, while the NEMA 3 enclosure protects it in demanding environments.

Key specifications include 75 in-lb torque, a driving power of 12 VA, and compact dimensions (5-1/2 in W x 7-5/16 in D x 6-7/16 in H). It operates from -40 to 150 degrees Fahrenheit and offers a precise 30–60 second actuation timing. The unit mounts via a convenient foot-mount and uses quick-connect terminals for fast wiring. The package includes a transformer and an auxiliary switch for seamless integration with control systems.
