Weil McLain 381-354-580 Inducer Assembly

The Weil McLain 381-354-580 Inducer Assembly is a direct-replacement inducer fan assembly kit designed specifically for Weil-McLain CGi Series 1 boilers. This critical exhaust blower component manages the expulsion of flue gases and ensures precise airflow for optimal combustion efficiency. Operating at 120V and pulling 0.6A, the 1/20 HP motor provides the necessary static pressure to maintain safe venting cycles. As a complete service kit, it includes the inducer fan assembly, high-temperature gasket, and mounting nuts, allowing for a tight seal against the heat exchanger and reducing field labor during boiler maintenance or emergency repairs.

For technicians servicing hydronic heating systems, this OEM replacement part handles the rigorous duty cycles of residential gas boilers while minimizing vibration and noise transfer. By ensuring a consistent air-fuel mixture, the 381-354-580 prevents common lockout issues associated with pressure switch failures or restricted venting. Always verify the part number against the specific boiler revision to ensure electrical and mounting compatibility before installation.

• Optimized Combustion: Precision-balanced fan blades deliver exact airflow for consistent burner performance.
• Full Installation Kit: Includes the essential gasket and hardware to ensure a gas-tight seal and prevent flue gas leakage.
• Durable Construction: Engineered to withstand high-temperature exhaust environments in CGi Series 1 applications.
• Reduced Downtime: Direct-fit OEM specification eliminates the need for field modifications or wiring adjustments.
