Tunnel Ventilation

Good ventilation is an essential part of the planning process for modern tunnel design

In road and rail tunnels where passenger safety and comfort is essential, it is important to plan the ventilation system carefully. Vehicle tunnels and metros have to be able to meet the air flow demands which match changing traffic conditions, as well as being able to remain in operation during emergency situations.

Howden tunnel ventilation fans perform this task efficiently, reliably and quietly, and are designed to remain operational during extreme temperature conditions.
