Multi Products 3159A Actuator

The Multi Products 3159A Actuator is a heavy-duty, 120V Torque Box motor designed for critical damper control and ventilation automation in commercial HVACR systems. As a veteran-grade replacement actuator, this unit features a CW (clockwise) rotation and a versatile Type G dual shaft configuration, allowing for seamless integration into existing damper linkage assemblies. The UL14 recognized impedance-protected coil and dust-proof zinc die-cast housing ensure long-term reliability in demanding industrial environments where precision and high stall torque are non-negotiable for system efficiency.

For contractors servicing Air Balance or specialized ventilation equipment, the 3159A provides a robust 2 RPM rated speed and 70 in-lb of stall torque. Engineered with a heavy-duty metal geartrain, this dual shaft motor is specifically optimized for HVAC damper applications requiring low back gear torque, facilitating smoother operation in spring-return and automated setups. Integrating the Multi Products 3159A ensures your ventilation control systems meet stringent safety standards while maintaining the mechanical integrity required for consistent airflow management.

• Dual Shaft Versatility: The Type G dual shaft design provides flexible mounting options for various HVAC actuator linkage requirements.
• High Torque Performance: Delivers 70 in-lb of stall torque, ideal for managing large damper blades and heavy-duty ventilation louvers.
• Industrial-Grade Build: Features a rugged zinc die-cast housing and heavy-duty metal geartrain for superior mechanical durability.
• Safety Compliance: UL14 recognized and impedance protected, ensuring safe operation within 120V electrical systems.

Is the 3159A compatible with my existing damper shaft?
This model uses a Type G dual shaft. One side is approximately 0.50" diameter while the other is 0.31". Always verify your damper linkage dimensions and rotation (CW) before installation.

Can I use this for spring-return applications?
Yes, the Multi Products 3159A is designed with low back gear torque, which is essential for proper function in spring-return damper assemblies.

What are the electrical requirements for this motor?
This is a 120V AC actuator with a stall current of 0.16 Amps. Ensure your control circuit matches these specifications to prevent electrical failure.
