Multi Products 2781 Actuator

The Multi Products 2781 Actuator is a high-performance gearmotor solution engineered for precision damper control in commercial HVAC and industrial ventilation systems. This heavy-duty 120V actuator motor utilizes a shaded pole design within a rugged, dust-proof zinc die-cast housing, ensuring reliable operation in demanding environments. Frequently used in replacement motor applications for Ruskin and other major damper brands, this model features counter-clockwise (CCW) rotation and a Type C round shaft configuration for seamless mechanical integration. With a stall torque rated at approximately 45 in-lb and a synchronous speed of 2 RPM, it provides the necessary force for consistent air modulation. The unit is UL6 recognized, highlighting its compliance with rigorous safety standards for impedance protected coils. For contractors performing HVAC system maintenance or actuator motor replacement, this 2781 model offers a drop-in technical solution that prioritizes geartrain durability and long-term stall-duty performance.

• Industrial Durability: Features a heavy-duty metal geartrain and zinc die-cast housing to withstand high-cycle ventilation control environments.
• Precise 2 RPM Output: Delivers consistent, low-speed timing essential for accurate damper positioning and airflow regulation.
• High Stall Torque: Rated for 45 in-lb stall torque to handle the resistance of large commercial HVAC dampers without overheating.
• Ease of Installation: Standard Type C round shaft and 120V power requirements facilitate fast field swaps for technicians.
• Safety Compliance: UL6 and UL14V compliant design with an impedance protected coil for enhanced operational safety.

Is the Multi Products 2781 compatible with Ruskin dampers?
Yes, the 2781 is a common technical replacement for older Ruskin damper motors. Technicians should verify the CCW rotation and round shaft dimensions to ensure a proper fit with existing linkages.

What is the difference between the 2781-A and the 2781?
The standard 2781 typically denotes Counter-Clockwise (CCW) rotation, whereas the "A" suffix often indicates Clockwise (CW) rotation. Always check the rotation direction of your specific damper actuator motor before installation.

Does this unit require a run capacitor?
No, this specific 120V shaded pole gear motor operates without an external capacitor, simplifying the wiring process for field service technicians.
