Multi Products 2781S Actuator

The Multi Products 2781S Actuator is a heavy-duty industrial solution designed for precise control of damper and ventilation systems. Operating on a 120V power supply, this UL6 rated actuator features a counter-clockwise (CCW) rotation and is built with a type B square shaft configuration for secure mechanical interface. Engineered for the rigors of commercial HVACR environments, the unit is housed in a dust-proof zinc die-cast housing and utilizes a heavy-duty metal geartrain to ensure consistent torque delivery and long-term reliability in high-cycle applications. As a direct replacement actuator motor, the 2781S is often identified as a Torque Box actuator, providing a high-stall torque around 45 in-lb to manage demanding air-side components. This HVAC damper motor is essential for technicians requiring a drop-in 120V replacement that meets strict safety standards while maintaining low back-gear torque for specific spring-return or atmospheric control requirements.

• Industrial Durability: Constructed with a rugged zinc die-cast housing and internal metal gears for maximum resilience.
• Reliable Performance: Delivers precise 2 RPM speed and high stall torque for consistent damper positioning.
• Safe Integration: Features a UL6 compliant, impedance-protected coil for enhanced electrical safety in commercial settings.
• Application Specific: The Type B square shaft and CCW rotation ensure compatibility with specific OEM ductwork assemblies.

What is the primary application for the Multi Products 2781S?
This 120V HVAC actuator is primarily used as a damper control motor in ventilation and air management systems where a square shaft and counter-clockwise rotation are required for mechanical actuation.

Can I use this model if my current system requires a round shaft?
No, the 2781S utilizes a type B square shaft. If your configuration requires a round shaft, you would typically look for the standard 2781 model or verify the specific shaft dimensions against the HVAC part number.

Does this actuator support 24V control circuits?
This specific model is a 120V AC actuator. For low-voltage 24V applications, a different version or a step-down transformer would be necessary to ensure compatibility with the control signal.
