Greenheck 826840 Actuator
The Greenheck 826840 Actuator, specifically the MP-100 115-230V model, is a vital component for technicians converting WD-100 series backdraft dampers to motorized operation. This spring return actuator is designed for horizontal mount configurations, ensuring reliable damper closure during power loss through integrated spring tension. Engineered for durability, the multi-voltage motor pack operates on 115V or 230V (50/60Hz), offering flexibility for diverse commercial HVAC and industrial ventilation projects. As a UL Listed internal actuator kit, the 826840 includes essential mounting hardware and actuator arms to facilitate professional damper motor replacement or new installs on single or double panel systems. For contractors, the impedance protected shaded pole motor provides a stall-type design that prevents burnout during prolonged hold periods. When your system requires precise HVAC damper control, this Greenheck motor pack offers the mechanical advantage needed to maintain airflow integrity and energy efficiency in demanding environments.
Key Benefits
- Universal Voltage Compatibility: Supports both 115V and 230V power supplies, reducing the need for multiple SKUs on the service truck.
- Fail-Safe Performance: Features a spring return mechanism that guarantees the damper returns to a closed position during electrical failure.
- Complete Installation Kit: Includes the actuator bracket, arm assembly, and linkage hardware required for a seamless field conversion.
- Industrial-Grade Construction: Built for WD-100 series dampers with a focus on longevity in high-cycle ventilation applications.
- Precision Linkage: Adjustable actuator arms ensure the blades achieve a tight seal to prevent backflow and air leakage.
Common Questions
Can the MP-100 be used on vertical mount dampers?
No, the Greenheck 826840 is specifically designed for WD-100 horizontal mount dampers. For vertical exhaust applications, a different motor pack series should be selected to match the gravity load requirements of the blades.
How do I adjust the closing force of the damper?
The integrated actuator spring can be adjusted during installation. Technicians should apply just enough tension to ensure complete blade closure without overstressing the motor during the opening cycle.
What should I check if the motor fails to open the damper fully?
First, verify the supply voltage matches the internal wiring configuration (Blue for 115V, Brown for 230V). Then, inspect the damper linkage for binding or "out of square" frames that may be causing mechanical resistance.
