why use tunnel jet fan

Tunnel jet fans are used for ventilation and smoke control in tunnels and other confined spaces. They help to remove air contaminants, such as exhaust fumes and dust, by creating a continuous flow of fresh air through the tunnel or space. In the event of a fire, they can also be used to extract smoke, heat, and toxic gases from the area, ensuring that occupants have a clear escape route and reducing the risk of structural damage. Additionally, they can help to regulate the temperature and humidity levels in an underground or enclosed environment, improving the overall comfort and safety of those inside.
