Multi Products 3754 Actuator

The Multi Products 3754 Actuator is a field-proven 120/240V actuator designed for heavy-duty damper motor replacement and industrial ventilation control. Engineered with a rugged torque box architecture, this unit features a dual-voltage 110-240V AC impedance-protected coil within a high-grade zinc die-cast housing. This HVAC actuator delivers a consistent 2 RPM output with a robust stall torque of 70 in-lb, making it the go-to choice for technicians managing spring return applications and industrial air-handling units. The metal geartrain is built to withstand high-cycle environments, providing low back-gear torque to ensure reliable damper positioning even in complex zoneline systems. By utilizing this replacement actuator motor, contractors can ensure seamless HVAC part compatibility across a wide range of OEM equipment, maintaining system efficiency without the need for extensive retrofitting. Designed and manufactured in the USA, the model 3754 maintains strict performance standards for mission-critical environmental control.
