Multi Products 3756 Actuator

The Multi Products 3756 Actuator is a heavy-duty 24V replacement motor engineered specifically for Greenheck damper systems and industrial ventilation applications. As a veteran-grade gear motor solution, this unit is designed to replace legacy components like the MP2986A, providing consistent torque for precise airflow control in demanding environments. Built with a rugged steel frame and a compact housing footprint, the 3756 ensures seamless integration into existing VCD (Volume Control Damper) assemblies without extensive field modifications. For technicians managing building automation, this 24VAC low voltage actuator offers the high-starting torque required for intermittent duty cycles in dust collection, process cooling, and general HVAC exhaust systems. Its specialized winding and gear ratio are optimized for the TB2001 torque box configuration, maintaining reliable performance across a wide operating temperature range. As an industry-standard component for Greenheck 24V systems, the Multi Products 3756 is the go-to choice for contractors prioritizing mechanical durability and exact OEM compatibility.

• Direct OEM Replacement: Functionally replaces obsolete Multi Products part numbers, including 2986A, ensuring 100% compatibility with Greenheck 826859 kits.
• Enhanced Torque Output: Optimized gear train designed for high-cycle industrial dampers and ventilation shutters.
• Robust Construction: Features a durable steel frame and zinc die-cast gearcase for long-term mechanical stability.
• Low Voltage Efficiency: Standard 24V power input integrates directly with most existing HVAC control transformers and BAS controllers.
• Precise Control: Maintains exact airflow positioning to help optimize system-wide operating conditions.

Is this motor compatible with 120V systems?
No, the 3756 is specifically wound for 24V AC operation. If your system requires 120V, you would typically need the MP-3754 model. Always verify your supply voltage at the transformer before installation.

Does this include the linkage and hardware?
This item is the actuator motor (3756) only. If you are performing a full field conversion or replacing a different brand, you may need separate Greenheck linkage kits or hardware specific to your damper model.

Can I use this for modulating service?
The 3756 is a two-position (On/Off) actuator motor. For applications requiring 0-10V or 4-20mA modulating signals, verify the specific control sequence required by your building automation system before swapping components.
