About Protan expand_more
Some tunnels start as an opening on the surface, but many service tunnels begin at the bottom of a vertical shaft.
In such tunnels it is crucial for the ventilation system to ensure the supply of fresh air down to the tunnel and to provide practical, airtight and durable transitions from a vertical to a horizontal ventilation duct system.
How it works
Protan Ventiflex Air is a concept for mines and tunnels in which membrane materials, couplings and welding technology combine to create a world-class ventilation duct system.
Protan Ventiflex Duo is a concept developed to transport air through narrow passages or in tunnels with restricted height, without compromising air flow.
Protan Ventiflex Shaft has been developed for the vertical supply of fresh air through a shaft construction.
Protain Ventiflex Antistatic systems are ventilation solutions for mines and tunnels where the risk of explosion is high.
