Honeywell Commercial MS8104F1010 Damper Actuator

The Honeywell MS8104F1010 Damper Actuator delivers reliable 24V AC control as a compact SPST, direct-coupled damper actuator. Its 2-Position, spring-return design ensures fast actuation and consistent position when controlling HVAC dampers. With a rugged aluminum body and a 1/2 inch shaft, this actuator is built for demanding environments while maintaining smooth, repeatable operation.

Designed for fire and smoke applications, it features a NEMA 1, IP40 enclosure and a 95-degree rotation to fit standard damper assemblies. The unit provides up to 30 in-lb torque, a 15-second actuation timing, and operates from a 24V AC supply at 50/60 Hz. Compliance with UL 873 and CUL/C-Tick approvals adds safety and reliability to commercial HVAC projects.
