The Packard 66847 Draft Inducer Motor is a combustion air part, which is used in HVAC systems and specifically in gas-fired furnaces and heating elements. It can run at 3000 RPM on 120V power with an airflow rating of 105 CFM, and combustion gases are pulled through the heat exchanger and vented out of the system. It is fitted to the furnace exhaust to set up the right draft conditions before the ignition of the burner.
