Multi Products 1424 Actuator

As a core component in many zoning and ventilation systems, the Multi Products 1424 Actuator is engineered for high-torque, low-speed damper control. This 120V AC HVAC actuator operates at a precise 2 RPM with a standard clockwise (CW) rotation, making it a reliable drop-in for damper motor replacement in residential and commercial air handling units. Its 3/16-inch square output shaft provides a secure, non-slip connection to standard HVAC zone dampers and louvers, ensuring consistent airflow regulation throughout the system.

The Multi Products 1424 features a rugged zinc die-cast housing designed for the demanding environments of mechanical rooms. With an impedance-protected coil and heavy-duty metal geartrain, this 2 RPM actuator motor delivers steady performance without the risk of overheating during continuous duty cycles. For technicians troubleshooting HVAC actuator symptoms like restricted airflow or noisy operation, this direct-drive solution offers the high-performance torque required to move large damper banks or stuck linkages. Integrating this 120V CW actuator ensures your automation system maintains optimal static pressure and temperature control.

• High-Torque Performance: The heavy-duty metal geartrain ensures consistent 2 RPM speeds even under the load of large dampers.
• Universal Compatibility: Features a standard 3/16" square shaft actuator design that fits most common HVAC linkage systems.
• Durable Construction: The dust-proof, zinc die-cast housing protects internal components in harsh industrial environments.
• Easy Installation: Designed as a direct 120V replacement actuator motor for rapid field service and reduced downtime.
• Reliable Operation: The impedance-protected coil prevents motor burnout if the damper blades become mechanically obstructed.

What are the symptoms of a failing Multi Products 1424 actuator?

Common signs include clicking or grinding noises (stripped gears), failure of the damper to reach the fully open or closed position, or a lack of response to 120V power signals despite a healthy control board.

Can I use a 24V actuator as a substitute for the 1424 model?

No, the 1424 is a 120V AC component. Using a 24V unit without a transformer will result in immediate failure. Always verify your supply voltage and rotation direction (CW vs. CCW) before installing.

Is the 3/16" square shaft compatible with round damper shafts?

This specific model is designed for square-input linkages. If your damper uses a round shaft, you may need a universal mounting adapter or a different shaft-style motor to ensure a secure mechanical fit.
