Fasco A079 Inducer Blower
The Fasco A079 Inducer Blower is a critical 115V, single-speed technical component designed for high-efficiency thermal exchange in residential heating systems. Operating at 3000 RPM with a 1.1 Amp draw, this shaded pole motor features a CCW rotation (counter-clockwise) and is engineered with Class B insulation to handle ambient temperatures up to 40°C. As a veteran-grade HVAC draft inducer replacement, the A079 provides a direct mechanical fit for the Universal 577 and several legacy Rheem, Goodman, and York furnace models. The unit utilizes a 3.3-inch diameter motor and a sleeve bearing system, ensuring a balance between operational longevity and reliable vertical or horizontal mounting. The rectangular outlet design without a flange facilitates a seamless transition during furnace blower motor swaps, while the internal thermal protection prevents winding failure during restricted airflow conditions. For contractors, the 24-inch leads with stripped and flag terminals simplify the electrical integration into existing 60Hz control boards.
