Tunnelling Ventilation  Deduster

Ventilation during tunnel construction is needed so to provide the external air required to dilute the pollutants produced by the machines used during the different stages of the manufacturing. The working squads a safe environment.

Our wide product range ensures you the most suitable solution for ventilation in the construction phase of the tunnel. We can size the systems in accordance with the enforced laws. The product range consists of axial fans single or multi staging to achieve the required system pressure for any tunnel length. High-tensile ventilation ducts, efficient inverters and reliable dedusters complement our system.
