This professional-grade Combustion Air Blower is a high-performance draft inducer motor assembly designed for high-efficiency gas-fired heating systems and commercial rooftop units. Operating as a dual-speed venter motor, it is engineered to safely exhaust combustion gases through the flue while maintaining optimal airflow for ignition. Running on 208-230V at 60Hz, this 2-speed assembly allows the HVAC system to modulate performance, improving energy efficiency and reducing operational noise. A reliable draft inducer is essential for preventing pressure switch errors and ensuring the furnace or rooftop unit completes its startup cycle safely. This replacement combustion fan is ideal for restoring proper ventilation and system performance in light commercial HVAC applications.
