Lochinvar & A.O. Smith 100144972 Fan Motor Assembly

The Lochinvar & A.O. Smith 100144972 Fan Motor Assembly is a critical OEM component engineered for high-performance combustion and ventilation in commercial water heaters and boilers. As a direct replacement for the discontinued Lochinvar FAN2723, this assembly is built to original manufacturer specifications to ensure seamless integration and factory-speed recovery for damaged or inefficient induction systems. Specifically designed for Copper-Fin and EnergyRite series, it maintains the precise static pressure required for optimal burner performance and heat exchanger protection.

For service contractors, the 100144972 fan motor provides a plug-and-play solution that eliminates the risks associated with universal or aftermarket parts. This centrifugal blower assembly is optimized for models ranging from 987,000 to 1,257,000 BTU/hr, delivering consistent air-fuel ratios essential for low-emission operation. Its heavy-duty housing and balanced impeller minimize vibration, significantly extending the operational life of the induction system in high-demand mechanical rooms.

• OEM Compatibility: Serves as the official successor to FAN2723, ensuring an exact physical and electrical match for Lochinvar boiler parts.
• Enhanced Airflow Management: Engineered for combustion air induction, providing the reliable ventilation needed for A.O. Smith and Lochinvar heating units.
• Contractor-Grade Durability: Features high-torque motor windings designed to withstand the thermal stress of continuous commercial duty cycles.
• Precision Performance: Maintains factory-set RPM to satisfy pressure switch requirements and prevent nuisance lockouts on ignition.

Is this compatible with older EnergyRite pool heaters?
Yes, this assembly is the correct replacement for FAN2723 typically found in EnergyRite ER models and Copper-Fin CB/CW 987-1257 series units.

Does this assembly include the necessary gaskets?
This is the fan motor assembly only. It is recommended to verify the condition of the mounting gasket (part 100233678) during installation to ensure a proper airtight seal.

Can I use this motor for other BTU ranges?
This specific assembly is calibrated for 987 to 1257 series models. For larger models such as the 1437-2067, a different fan assembly (typically 100144992) is required to meet the higher airflow demands.
