Lennox 86K37 Actuator

The Lennox 86K37 Actuator is a high-torque, spring-return motorized solution designed for precise regulation in commercial and residential HVAC systems. Identified by the manufacturer model MS7110K2006, this 24V power-driven component delivers a robust 88 lb-in (10 Nm) of torque, ensuring reliable damper and valve positioning even in demanding high-static environments. As a veteran-grade OEM replacement actuator, it provides a direct field-swap for legacy Lennox 86K3701 and Honeywell ML7285A1015 models, eliminating the need for complex mounting modifications or linkage adjustments. Featuring a self-centering shaft adapter and a NEMA 2 rated enclosure, the MS7110K2006 actuator supports both 0/2-10 Vdc modulating control and floating signals. Its 95-degree mechanical stroke and rapid 20-second spring return timing provide the fail-safe security necessary for critical ventilation and zoning applications. This 24V 88 lb-in actuator is engineered for mid-to-large scale dampers, providing the consistent feedback and mechanical longevity required by professional contractors to maintain optimal airflow and thermal efficiency.

• Direct Replacement Compatibility: Seamlessly replaces 86K3701, ML7285A1015, 56M81, and 97J37, ensuring zero-downtime installations.
• High-Torque Performance: Delivers 88 lb-in (10 Nm) of driving torque to handle heavy damper loads and multi-zone commercial assemblies.
• Fail-Safe Spring Return: Integrated mechanical spring ensures the damper returns to a safe position during power loss in under 25 seconds.
• Versatile Control Input: Built to accept 2-10 Vdc modulating or floating control signals for precise environmental management.
• Simplified Mounting: Equipped with a self-centering shaft coupling that accommodates various shaft sizes without extra hardware.

What systems is the Lennox 86K37 compatible with?
This actuator is a standard component in many Lennox packaged rooftop units and large-scale air handlers. It is specifically designed to function as the primary damper actuator motor for systems previously using Honeywell ML7285 series or earlier Lennox 86K/97J part numbers.

Does this model support 0-10V or 2-10V feedback?
Yes, the MS7110K2006 provides a 2-10 Vdc feedback signal, allowing your building automation system or thermostat to monitor the exact position of the damper blades for advanced diagnostic reporting.

Can the rotation direction be adjusted during installation?
The actuator is reversible. By simply flipping the unit on the shaft, you can select between clockwise (CW) or counter-clockwise (CCW) spring return to match the required fail-safe orientation of your specific damper assembly.
