Our flexible ventilation systems for mines and tunnels are among the most innovative in the world.
All our systems are custom-made to purpose for each project and supplied in five different qualities of ductings.
All five are flame retardant and self-extinguishing. In addition, two have anti-static qualities and are especially developed for environments in which flammable gases are present.
We work continuously to drive the development of ventilation technology in mines and tunnels. We are a member of the NTN (Norwegian Tunneling Network) and we offer extensive training and user support to our Ventiflex clients. We maintain close dialogue and good cooperation with our clients, and training is included for installation, suspension and repairs.
Together with our collaboration partners, we supply several hundreds of kilometres of ventilation ducts to mines and tunnels every year. These are part of exciting and challenging projects in Nordic countries and the rest of Europe, South America, Asia, Africa and Australia.
The Ventiflex products are produced and assembled in Norway. The coated textile is produced in Drammen, while the ducts are manufactured in a factory in Nesbyen.
Our factories and our ventilation systems are approved and certified in accordance with the quality standard ISO 9001 and environmental standard ISO 14001.
This means the entire value chain and all ventilation solutions are of documented high quality and have minimal impact on the environment, both locally and globally.
We develop and test all solutions and their quality at our laboratory in Drammen. The laboratory is approved by world-leading Norwegian certification society Det Norske Veritas (DNV) and follows strict testing and documentation routines.
All systems undergo in-depth monitoring and quality assurance before delivery.
Through innovation and continuous improvement, we always strive to offer the best duct quality that is:
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.
All Ventiflex fittings are developed to optimise airflow in accordance with the laws of aerodynamics. Our solutions are also produced in the strongest duct quality to withstand high stress.
