Tunnel Ventilation Systemair

2018-1-17  Longitudinal ventilation Longitudinal ventilation is accomplished by using jet fans that, by accelerating a small part of the air present in the tunnel, through an exchange of momentum, are able to induce, on the overall air inside the tunnel, a movement in the willed direction. The same is accomplished for fire smoke propagation control.
