Daikin-McQuay 300049498 Motor

The Daikin-McQuay 300049498 Motor is a precision-engineered OEM replacement motor designed for specific fan coil and air handling applications. Operating at 115V with a 1/8 HP output, this single-phase induction motor maintains a steady 700 RPM, ensuring optimal airflow and static pressure performance in McQuay thin-line units. Technical specifications include a 42 frame size and permanent split capacitor (PSC) design transitions, which are critical for maintaining system efficiency and reducing noise levels in commercial HVAC settings. For contractors, the Daikin 300049498 provides a drop-in fit, utilizing a standard 1/2 inch shaft and resilient mounting to mitigate vibration. This HVAC blower motor is the direct replacement for legacy McQuay parts, ensuring that the electrical load and thermal protection match the original equipment manufacturer’s requirements. Correct installation prevents overheating and preserves the integrity of the blower wheel assembly.

• Direct OEM Compatibility: Engineered specifically for Daikin-McQuay fan coil units, ensuring correct shaft alignment and electrical termination.
• Optimized RPM Profile: The 700 RPM low-speed operation is calibrated for quiet, consistent airflow in hospitality and office environments.
• Robust Electrical Design: Features internal thermal overload protection and high-grade insulation to handle continuous duty cycles.
• Efficient Performance: 1.8 Amp draw at 115V provides a balance between torque requirements and energy consumption.

Is this a direct replacement for my older McQuay fan coil motor?
Yes, the 300049498 serves as the primary replacement for various thin-line and ceiling-mounted fan coil units. Verify the 1/8 HP and 700 RPM specs against your existing motor nameplate for confirmation.

What capacitor is required for this motor?
As a PSC motor, this unit requires a specific run capacitor. Always check the motor label for the microfarad (MFD) rating, as running a motor with the incorrect capacitor can lead to premature winding failure.

Can I use this motor in a 208-230V system?
No, this motor is rated strictly for 115V single-phase applications. Installing this on a 230V circuit will cause immediate electrical failure.
