Multi Products 1493 Actuator

As a field technician, you know that finding an exact replacement for high-voltage damper controls is critical for maintaining system pressure and airflow. The Multi Products 1493 Actuator is a robust, stall-type 440V actuator engineered for heavy-duty commercial and industrial HVAC applications. Designed to handle the high-torque demands of HVAC damper control, this sub-fractional gearmotor excels in ventilation automation where consistent positioning is non-negotiable. Whether you are servicing a VAV system, exhaust dampers, or large-scale mixing boxes, this 440-volt motor provides the reliable mechanical force needed to actuate louvers without the risk of mid-cycle failure. Built with a durable zinc die-cast housing and a completely enclosed gearcase, it is the industry standard for damper motor replacement in environments ranging from agricultural greenhouses to industrial mechanical rooms. This OEM-quality component ensures your low-speed high-torque motor requirements are met with precision, preventing the common "hotdog machine" continuous rotation issues found in mismatched aftermarket parts.

• Stall-Type Design: Engineered to hold position under load, ensuring dampers remain in the required state without constant power cycling.
• Industrial Durability: Features a rugged zinc die-cast housing and enclosed geartrain to protect internal components from dust and debris.
• High-Voltage Compatibility: Specifically rated for 440V AC systems, eliminating the need for step-down transformers in industrial footprints.
• Proven Torque Output: Optimized for the high-resistance demands of large ventilation louvers and multi-blade damper assemblies.
• Precision Engineering: Manufactured to strict OEM standards to ensure seamless mechanical alignment with existing linkages.

How do I verify if this is the correct replacement for my existing motor?
Locate the 4-digit SPEC number stamped on your current housing near the output shaft. If your spec matches the 1493 series or your documentation calls for a 440v actuator with these physical dimensions, this is your direct replacement.

Does this actuator require a spring return?
This model is a stall-type motor typically used in applications where the motor holds the damper open or closed against a stop. Verify your wiring diagram to confirm if your system utilizes a power-open/spring-close or power-open/power-close configuration.

What applications is the Multi Products 1493 best suited for?
It is primarily used for HVAC damper control in commercial air handlers, industrial exhaust systems, and agricultural ventilation where high-voltage power is standard.
