Multi Products 2914B Actuator

Upgrade or service your commercial ventilation systems with the Multi Products 2914B 120V Actuator. This heavy-duty HVAC damper motor is a staple for contractors requiring reliable, high-torque performance in demanding airflow control applications. Engineered with a robust die-cast zinc housing and a precision-machined metal geartrain, the 2914B provides consistent 2-3 RPM operation for precise damper positioning. As a 120V AC electromechanical actuator, it integrates seamlessly into standard line-voltage control circuits, offering an impedance-protected coil to prevent overheating during stall conditions. Whether you are performing a replacement for Multi Products 2914B units or retrofitting older "Torque Box" style systems, this unit is built to withstand the rigors of continuous or intermittent duty cycles in industrial environments. Ensure your damper actuator wiring is properly configured to the specific rotation required—CW or CCW—to maintain optimal system pressure and ventilation efficiency.

Key Benefits

• Industrial Durability: Features a rugged zinc die-cast enclosure that protects internal components from dust and mechanical impact.
• Precision Geartrain: The heavy-duty metal gears ensure high stall torque and minimal backlash for accurate damper plate control.
• Simplified Integration: Designed for 120V AC systems with standard mounting footprints, making it a direct-fit solution for many commercial HVAC brands.
• Thermal Protection: Includes a UL-recognized, impedance-protected coil to maintain operational integrity under heavy loads.

Common Questions

How do I confirm this matches my existing motor?
Verify the 4-digit SPEC number stamped on your current actuator housing. This SPEC number dictates the specific shaft diameter, length, and rotation direction required for your linkage or damper shaft.

Can this actuator be used for spring-return applications?
Yes, the 2914B is designed with low back-gear torque, making it compatible with many external spring-return damper assemblies used in fire and smoke safety systems.

What should I check if the motor buzzes but does not move?
First, disconnect the actuator from the damper linkage to ensure the damper itself isn't seized. If the motor still fails to rotate under 120V power while disconnected, inspect the geartrain for mechanical obstructions.
