Ventiflex
Protan supplies the whole world with innovative and efficient ventilation systems for mines and tunnels. Ventiflex - the art of transporting fresh air.
When Protan introduced Ventiflex in 1949, we were the first in Europe to provide flexible ventilation ducts for mines and tunnels. Our ventilation ducts became an international success immediately. Since then, we have built an extensive know-how and broad-based experience that form the basis for today's worldleading products and solutions.
