Huge Ventilation Fans Just Like an Airliner's Engines: Understanding the Ventilation System Essential for a Safe Tunnel Environment

The Yamatogawa Route, measuring approximately 10 km in total length, fully opened in March 2020, connecting between Sakai City and Matsubara City in Osaka. Panasonic constructed the tunnel ventilation facilities for this route. Panasonic delivered more products than any other project of this kind in its history, including 78 large jet fans, each as big as an airliner's jet engine, as well as 64 electrostatic precipitators and 14 exhaust fans. In the following, the members in charge of the project at Hanshin Expressway Company and Panasonic talk about the project.
