Lochinvar & A.O. Smith 100188878 Fan Assembly
The Lochinvar & A.O. Smith 100188878 Fan Assembly is a critical OEM replacement component engineered specifically for the FTX500 series high-efficiency boilers. Designed to maintain precise combustion air ratios, this heavy-duty blower ensures optimal airflow for FTX500L and FTX500N models. As a veteran technician knows, maintaining the correct static pressure within the combustion chamber is vital for system longevity and peak thermal efficiency. This genuine combustion blower motor assembly provides the exact RPM and torque specifications required to meet manufacturer performance curves, preventing common issues like "lockout" due to insufficient airflow or flame instability. This part is a direct replacement for legacy part numbers FAN20014, FAN30016, and 100144910, ensuring a seamless mechanical fit and plug-and-play electrical integration. When replacing the FTX500 fan assembly, always verify the integrity of the mounting gasket to ensure a pressurized seal during high-fire operation.
Key Benefits- OEM Compatibility: Exact replacement for Lochinvar FTXL and FTX500 models, ensuring factory-standard modulation.
- Drop-In Integration: Fully replaces deprecated part numbers 100144910 and FAN30016 without field modifications.
- Enhanced Efficiency: Optimized for precise air-to-fuel mixing to maximize the boiler's condensing capabilities.
- Durable Construction: Built to withstand the continuous duty cycles and thermal stresses of commercial heating applications.
