International Environmental 70021523 Motor

The International Environmental 70021523 is a high-performance direct drive blower motor designed specifically for HVAC fan coil units (FCUs). This 1/30HP 115V 1075RPM motor is now superseded by the 71534804 motor, which serves as the manufacturer’s direct replacement. Built with a ball bearing motor design, this unit provides superior longevity and reduced friction compared to standard sleeve bearing alternatives, making it an essential component for maintaining consistent airflow in residential and light commercial hydronic systems. The PSC (Permanent Split Capacitor) design ensures optimal energy efficiency and a stable 60Hz single-phase operation, typically requiring a 5uF 370V capacitor for proper startup and run cycles. For contractors performing a fan coil motor replacement, this 1111 RPM (nameplate) rated motor features a durable rolled steel frame and aluminum flange for corrosion resistance in high-humidity environments.

Key Benefits:

• OEM Compatibility: Seamlessly replaces legacy part 70021523 and is compatible with D1SS240G28017A and M*Y03 units.
• Enhanced Durability: Features ball bearings and a thermally protected open air-over (OAO) enclosure to stand up to continuous duty cycles.
• Precision Performance: Maintains 1075 RPM at 115V for consistent static pressure and airflow delivery across the evaporator coils.
• Contractor-Grade Construction: Simplified wiring and a standard 42-frame-style diameter allow for efficient field installation.

Common Questions:

Is the 71534804 a direct fit for the 70021523?
Yes, the 71534804 is the official engineering replacement for the 70021523, sharing identical mounting characteristics and electrical specifications.

Does this motor include the run capacitor?
This item is the motor only. It is best practice to install a new 5uF 370V capacitor when replacing any PSC blower motor to ensure the system operates within nameplate amperage.

Can this motor be used in 208-230V systems?
No, this is a dedicated 115V AC motor. Applying higher voltage will cause immediate winding failure and is not supported.
