Lochinvar & A.O. Smith 100145019 Air Fan

Lochinvar & A.O. Smith 100145019 Air Fan

The Lochinvar 100145019 Combustion Air Fan is a critical replacement component designed for high-efficiency hydronic boilers and volume water heaters. Engineered for precise pre-mix combustion air delivery, this centrifugal blower assembly ensures optimal air-to-fuel ratios across various firing rates. Originally sourced under part numbers such as Lochinvar FAN3032, it is compatible with select Knight XL and Copper-Fin II models, as well as A.O. Smith Cyclone commercial water heaters. The 100145019 utilizes a 120V, brushless DC motor configuration to provide reliable ventilation pressure against heat exchanger resistance. When installing this OEM combustion blower, technicians should inspect the blower gasket and manifold seals to maintain airtight integrity. Accurate RPM feedback to the integrated control board allows for modulation stability, preventing nuisance flame failures or resonance during the startup sequence. This blower is essential for maintaining the AFUE rating and operational safety of commercial heating systems.

Key Benefits
  • OEM Compatibility: Precision-fit for Lochinvar Knight and A.O. Smith commercial units, ensuring seamless electrical connection and mounting.
  • Optimized Combustion: Maintains consistent static pressure for stable flame patterns and efficient fuel utilization.
  • Durable Construction: Features high-temperature resistant housing and balanced impellers to minimize harmonic vibration and bearing wear.
  • Modulating Performance: Supports variable speed operation for precise heat load matching.
Common Questions

Is the 100145019 compatible with older FAN3032 models?

Yes, the 100145019 is the direct functional replacement for the legacy FAN3032 part number, adhering to the same performance curves and mounting specifications.

Does this assembly include the replacement gasket?

While some assemblies may include a mounting seal, it is professional best practice to source a new flange gasket to prevent flue gas leakage or air bypass.

What are the symptoms of a failing combustion air fan?

Technicians typically identify failure through 'No Flame Established' lockout codes, excessive bearing noise (grinding), or the control board failing to sense correct blower tachometer signals.
