IEC or International Environmental Control in Oklahoma City manufactures quality well-designed HVAC motors out of America’s heartland. Their motors can be crossed from many brands’ part numbers, such as Fasco, GE, Genteq, and more. Most IEC motors are able to be shipped from factory stock, which takes between 3 and 4 business days. Many of these motors are found in casinos, hospitals, hotels, and other large commercial spaces such as universities. Their ease of installation make them a maintenance man’s favorite. If you find yourself with some fan motors which need replacement, IEC is a fantastic choice for your building efficiency.
International Environmental Corporation (IEC) building automation and fan coil systems keep your commercial HVAC infrastructure running efficiently. Because these specialized air-handling platforms rely on exact alignments of direct-drive blower motors, multi-tap power configurations, and customized hydronic heat exchanger coils, sourcing specific replacements for legacy climate cabinets requires technical precision. Contact our dedicated HVAC sourcing team today to locate your specific blower assembly, replacement heating/cooling coil, or drop-in hardware component.
IEC part number metrics follow a structured alphanumeric sequence that tracks internal component classes, performance capabilities, and operational voltage parameters. Review the hardware breakdown examples below to trace your active system tags.

Fan Coil Unit Maintenance Tip: When replacing an IEC multi-tap blower motor like the 50009109, always double-check the wire lead assignments on your system wiring diagram. Connecting an incorrect speed tap (High, Medium, Low) to your thermostat line-voltage relay can burn out the internal motor windings or cause improper airflow across your hydronic coil, potentially creating condensation issues inside the cabinet frame.
Maintaining balanced airflow and zone temperatures demands a clear understanding of fan coil configurations, motor multi-taps, and replacement coil parameters. Review our tailored hardware support answers below.
