Multi Products 2813C Actuator

The Multi Products 2813C Actuator is a heavy-duty 115V TB2000 series gearmotor designed for consistent performance in commercial and industrial HVAC applications. Built with a rugged zinc die-cast housing, this shaded pole motor and geartrain assembly is engineered to provide high-torque output for damper control, valve positioning, and air handling units. Operating at 2.2 RPM and 60 Hz, the 2813C offers the reliable, slow-speed rotation necessary for precise airflow adjustment in VAV boxes and ventilation systems.

This TB2000 actuator features a dust-proof enclosure and high-temperature bronze bushings, ensuring long-term durability in demanding environments. As a sub-fractional horsepower motor, it is optimized for high gear torque, allowing for easy backdrive in spring-return applications. For field technicians, the spec number stamped on the housing is critical for verifying exact shaft configuration and rotation requirements. This unit is a direct replacement for various Torque Box models, providing a seamless fit for legacy HVAC maintenance and newer installations alike.

• High-Torque Performance: The TB2000 geartrain is designed to handle the mechanical loads of heavy HVAC dampers and valves.
• Industrial-Grade Build: Features a zinc die-cast case and impedance-protected coils for maximum reliability in harsh duct environments.
• Precise Control: Enables accurate airflow regulation with a steady 2.2 RPM output, reducing hunting in automated systems.
• Versatile Integration: Operates on standard 115V 60Hz power, making it compatible with most commercial control circuits.

Is the TB2000 a universal part number?
No. TB2000 refers to the casting series. You must verify the specific 2813C designation or the 4-digit spec number on your existing unit to ensure matching shaft flats, keyways, and rotation.

Can this actuator be used in spring-return systems?
Yes, the Multi Products 2813C geartrain is designed for low back gear torque, allowing spring-return mechanisms to drive the actuator back to the safe position during power loss.

What maintenance is required for this gearmotor?
These units are permanently lubricated and sealed in a dust-proof housing, requiring no periodic maintenance under normal operating conditions.
