Midco International 646400 Blower Motor

Midco International 646400 Blower Motor

The Midco International 646400 Blower Motor is a critical component for maintaining precise combustion air requirements in power gas burners. This 115V blower motor is the direct replacement for 843512, engineered specifically for high-demand burner applications. Operating at a 1350/1000 RPM dual-speed range, it provides the necessary static pressure to stabilize the flame profile across various firing rates. With a low current draw of 1.38/1.2A and 50/60 Hz compatibility, this motor is optimized for energy efficiency without sacrificing torque. The inclusion of sealed ball bearings ensures minimal frictional resistance and long-term mechanical reliability in high-heat environments. Whether you are servicing a J81A-3 or a J120-3, this thermally protected motor prevents winding failure during heavy duty cycles, ensuring the burner assembly operates within OEM specifications.

Technical Benefits for Contractors

  • Direct OEM Compatibility: Serves as the verified 646400 replacement motor for Midco burner models J81A-3, J121A-3, J83-DS, J40-DS, J80-DS, J80-3, and J120-3.
  • Enhanced Durability: Features permanently lubricated sealed ball bearings and internal thermal overload protection to withstand the rigors of commercial boiler rooms.
  • Flexible Application: The 115V 1350/1000 RPM specification allows for precise airflow tuning to achieve optimal CO2 levels and combustion efficiency.
  • Industry Standards: This UL-recognized and CSA-certified burner motor ensures compliance with local mechanical codes and safety regulations.

Common Questions

Is this the correct motor for the Midco J Series burners?
Yes, the 646400 is the standard replacement blower motor for several J Series models. Always verify the shaft diameter and mounting flange configuration against your existing 843512 motor to ensure a drop-in fit.

Can this motor handle both 50Hz and 60Hz power supplies?
This motor is rated for 50/60 Hz frequency, making it suitable for a wide range of electrical environments while maintaining stable 1350/1000 RPM performance.

Does this motor require external lubrication?
No, the sealed ball bearing design is permanently lubricated, reducing maintenance requirements and preventing oil-related contamination within the burner housing.
