Daikin-McQuay 404222466 Variable Frequency Drive 5HP 380-480V VFD

The Daikin-McQuay 404222466 is a 5 horsepower Variable Frequency Drive (VFD) designed for use in Daikin-McQuay commercial HVAC systems. Operating on a 380–480V, 3-phase input, this drive provides precise electronic control of AC motor speed and torque, enabling fan and pump systems to ramp up and down in response to actual load demand rather than running at constant full speed.

Key Features:

• 5 HP (3.7 kW) power rating for commercial HVAC fan and motor applications
• 380–480V, 3-phase input voltage range for compatibility with standard commercial power supplies
• Smooth motor speed regulation reduces mechanical stress and extends motor and belt life
• Variable speed operation delivers significant energy savings compared to fixed-speed motor control
• OEM Daikin-McQuay replacement part — engineered for direct compatibility with Daikin-McQuay rooftop, air handling, and applied HVAC equipment
• Integrated motor protection features including overcurrent, overvoltage, and undervoltage fault detection

Replacing a failed or aging VFD with the correct OEM part ensures proper system communication, performance, and reliability. The 404222466 is intended as a direct replacement drive for qualified Daikin-McQuay equipment and should be installed by a licensed HVAC or electrical technician.
