Protan Business Area Ventiflex
Used worldwide, Protan Ventiflex is a ventilation system suitable for tunnels and other underground applications. The fabric is supplied in the form of a long duct. Outside the tunnel a powerful fan blows fresh air into the dict, and the fresh air drives exhausted air out. In this way the working climate at the tunnel face improves quickly after a detonation. At the Protan factory at Nesbyen, new and improved solutions are constantly being developed.
