Forced-air ventilating pipes designed for traffic tunnels

Flexible air pipes used for construction of ventilation systems. They are made of technical fabrics and are characterised by high mechanical strength and low weight, they are easy to transport and require less joints. Due to the low roughness of surface, their aerodynamic resistance is also reduced.
The technical fabric is individually selected pursuant to the requirements and needs of our Customers.
