Lochinvar & A.O. Smith 100233488 Fan Assembly

The Lochinvar & A.O. Smith 100233488 Fan Assembly is a critical combustion component designed for high-efficiency commercial boiler systems and water heaters. Engineered to deliver precise air-to-fuel ratios, this 115V blower assembly features a robust 1/2 HP motor operating at a sustained 1650 RPM. This part is a direct replacement for FAN2011 and is essential for maintaining stable combustion and thermal efficiency in Lochinvar Copper-Fin2 models (CP 502-752) and compatible A.O. Smith industrial units. As a veteran technician knows, the integrated induction blower motor and housing are balanced to minimize vibration and prevent harmonic resonance within the heat exchanger. This assembly ensures consistent forced-draft performance, mitigating common issues like ignition failure or rough operation caused by inadequate manifold pressure. When replacing this HVAC blower assembly, ensure all gaskets are seated correctly to maintain a gastight seal and prevent flue gas recirculation.

• Direct OEM Replacement: Seamlessly replaces Lochinvar FAN2011 and older A.O. Smith blower part numbers for quick field restoration.
• Optimized Performance: The 1/2 HP, 1650 RPM motor is spec-matched to maintain the specific static pressure required for forced-draft burners.
• Durable Construction: Built with industrial-grade internals to withstand the high-temperature environments typical of commercial heating systems.
• High Compatibility: Validated for use across multiple Lochinvar & A.O. Smith boiler and water heater product lines.

• Is this assembly compatible with non-condensing Copper-Fin2 models? Yes, this unit is the standard 100233488 fan assembly utilized in CP 502, 652, and 752 series heaters.
• Does this include the blower housing or just the motor? This is a complete blower fan assembly, including the squirrel cage, motor, and housing for a simplified installation.
• What causes these fans to fail prematurely? Most failures are attributed to intake debris blocking the radial burner or voltage fluctuations impacting the 115V motor windings.
