McQuay 107179808 ACTUATOR

The McQuay 107179808 is a professional-grade 24VAC HVAC actuator engineered for precise two-position control in commercial and industrial air handling systems. As a normally open (N/O) component, this unit ensures fail-safe performance by defaulting to an open state upon power loss, a critical requirement for maintaining airflow or fluid circulation in many Daikin McQuay configurations. This 2-position actuator is commonly utilized in valve control and damper applications, providing the dependable torque necessary to manage HVAC zone control and damper automation accurately. Designed for seamless integration, it is the direct replacement for Erie AG23A020 and AG23A020Q1 models, also cross-referencing to McQuay 107179810. Techs will appreciate the 18-inch leads and 50/60Hz compatibility, allowing for straightforward field installation into existing 24-volt control circuits. Whether you are performing a thermostat replacement or HVAC system diagnostics, this genuine OEM HVAC part maintains original equipment specifications for timing and electrical load, ensuring system stability without the risk of control lag or premature failure.

• Fail-Safe N/O Configuration: Automatically defaults to the open position during power interruptions to protect system integrity.
• 24VAC Versatility: Standard voltage requirement for broad compatibility with most commercial HVAC maintenance protocols and control boards.
• Precise 2-Position Logic: Reliable on/off actuation eliminates "hunting" and provides definitive state control for Daikin McQuay valves.
• Field-Ready Design: Features 18-inch wire leads for easy termination in crowded control enclosures or fan coil units.

Is the McQuay 107179808 interchangeable with Erie actuators?
Yes, this unit is the specified technical equivalent for Erie AG23A020 and AG23A020Q1, sharing the same footprint and 24V actuator electrical specs.

Does this actuator include an end switch?
No, the 107179808 is a standard 2-wire / 3-wire two-position control model without an integrated auxiliary end switch.

What systems typically use this 24VAC N/O actuator?
It is frequently found in water-source heat pumps, self-contained units, and air handlers where normally open valve operation is required for freeze protection or bypass flow.
