SmartFan mini is a self powered, efficient, clean & silent fan unit that greatly improves heat circulation from a solid fuel burning stove or a wood burning stove. - The device is powered by using the hot metal surface of the appliance to generate an electrical current to propel the fan blades instead of rising immediately to the ceiling. The rotating fan blades then propel the heat directly into the room area. - Helps to heat the room faster. - Safe & silent. - No electricity or batteries required.
