International Environmental 70556380 Motor

The International Environmental 70556380 Motor is a direct-drive, high-performance blower motor designed specifically for IEC fan coil units and modular air handlers. Operating at 208-230V, this 1/5 HP permanent split capacitor (PSC) motor delivers a consistent 1075 RPM, providing the static pressure required for multi-speed residential and light commercial HVAC applications. Drawing a nominal 1.29 Amps, it maximizes electrical efficiency while maintaining the torque necessary for vertical and horizontal configurations. This OEM replacement motor features a standard NEMA frame diameter and resilient mounting compatibility, ensuring reduced vibration and noise transfer across the cabinet. Technicians should verify capacitor MFD ratings and secondary lead wire configurations during field installation to ensure proper airflow across the coil. Engineered for continuous duty, the IEC 70556380 is the standard for maintaining factory-specified air delivery in HVAC repair and preventative maintenance cycles.

Key Benefits

• High-Efficiency Performance: The 1075 RPM speed rating ensures the unit meets original airflow design specifications for cooling and heating stages.
• Industrial Durability: Built with high-grade copper windings and internal thermal protection to handle high-static environments without premature motor burnout.
• Precise Electrical Specs: Rated at 208-230V and 1.29AMP, allowing for stable operation with existing fan relays and control boards.

Common Questions

What are the wiring lead colors for this motor?
Standard lead wires typically follow the IEC color code for line voltage, neutral, and capacitor connections, but always refer to the specific wiring diagram on the motor housing for field termination.

Is a new run capacitor required for installation?
It is standard field practice to replace the run capacitor when installing a new 1/5 HP HVAC motor to ensure the start-up torque and operational efficiency meet rated specifications.

Can this motor be used in high-humidity fan coil units?
Yes, this motor is designed with insulation classes appropriate for fan coil units where moisture and ambient temperature fluctuations are common during the cooling season.
