Ventilation systems in road and railway tunnels

Ventilation systems in road and railway tunnels play an essential role. Why? How?

Every tunnel relies on its ventilation system, essential not only for comfort, but above all for safety. Road and railway tunnels are confined spaces that can accommodate up to 200,000 vehicles per day.

The ventilation system ensures a constant supply of fresh air, which is essential to minimize carbon dioxide levels and other harmful substances.

Proper airflow is therefore critical to dilute and remove airborne pollutants, ensuring a healthy environment for both users and maintenance teams.

In emergency situations, such as fires, ventilation becomes critical. Smoke extraction solutions (longitudinal or fully transverse ventilation) control smoke propagation, enabling safer evacuation and more effective intervention by emergency services.

F2A designs ventilation solutions tailored to the specific challenges of each tunnel, ensuring reliable operation under all conditions.
