Jet fans, also known as induction fans, are specially designed ventilation fans that generate high-velocity air jets to move large volumes of air through enclosed spaces. Instead of using traditional duct systems, jet fans create a longitudinal airflow by transferring momentum to the surrounding air, providing an efficient and flexible ventilation solution.

They are widely used in road tunnels, underground parking garages, subway systems, and other enclosed facilities for daily ventilation, air quality control, and smoke extraction during emergencies
