Ventilation System

By Protan

Our flexible ventilation systems for mines and tunnels are among the most innovative in the world. When Protan established Ventiflex in 1949, we were the first in Europe to supply flexible ventilation ducts for mines and tunnels. Through almost 70 years we have gained extensive expertise and experience, which has created the foundation for today’s world-leading products and solutions. The ducting qualities in the Ventiflex series are designed and manufactured in a membrane specially developed for ventilation ducts. The polyester textile is knitted, not woven, to minimize the length and size of any damage or tears. The textile, and thus the membrane, is stronger radially than axially owing to its air pressure characteristics. A fully automated welding system.
