Protan Ventiflex Shaft

Click on Picture to Enlarge ..

Protan Ventiflex Shaft has been developed for the vertical supply of fresh air through a shaft construction.

Vertical supply of fresh air

Some underground constructions require supply of fresh air through vertical shafts. To accommodate this challenge, Ventiflex can supply a shaft-ducting system, designed to meet the unique demands such a system requires.

Present day, the deepest installation is 1,400 meters from the surface, expressing the quality and reliability of our design.

Flexible solutions

Protan Ventiflex Shaft is made with two, three or four suspension ribs, which are secured to wires using special non slip hooks and clips. There is a turnbuckle at one end of the wire to ensure correct alignment. Our solutions are flexible, and we supply duct lengths for both excavation and static installations. We also offer any duct diameter from ø200 mm to ø3,200 mm in all duct lengths.

In the worst case, a lack of fresh air in mines and tunnels can bring the project to a standstill.
