Ventiflex is known for the art of transporting fresh air into mountains with ventilation for mines and tunnels. Protan were the first in Europe to manufacture flexible ventilation ducts and over the years we have built up extensive know-how and broad-based experience, from which our customers benefit. We now supply several hundred kilometres of ventilation ducts a year. Our qualities offer outstanding durability, flexibility and low weight. The long service life of our ventilation ducts means that many of our customers re-use them extensively– which is good for the environment.
Ventiflex systems are used in mines and tunnels world wide, this is from a project in India.
