Zusammenfassung:	A jet fan system disposed inside a tunnel is disclosed. The system includes a jet fan device and a power supply device. The jet fan device includes a jet fan, a double-axis motor, a joint-type self-power generation module and a magnetic coupling configured to be driven in a driving mode in which the jet fan is driven by the double-axis motor or a self-power generation mode in which the jet fan rotates by natural wind based on rotational speed of the jet fan. By providing this jet fan system, power efficiency is improved.
