Tunnel Ventilation

Tunnel Ventilation

Tunnel fans are used in two different occasions:
- During tunnel construction, when it is necessary to remove the air contaminated by mechanical equipment and underground detonations.
- After the tunnel is complete, it is necessary to clean the air contaminated by the gases emitted by vehicles passing through the tunnel. Designs are typically scaled to the worstcase scenario, considering heavy traffic and/or accidents with smoke and fire.
