Ventilation Ducting
Protan produces flame-retardant Ventiflex ducting for use in underground projects. These PVC-coated ventilation ducts offer optimal strength, stability and safety, as well as improved tear-resistance and airflow. A unique mounting system provides longitudinal suspension with welded PVC eyelets along the entire duct. Available in lengths up to 500 m and diameters up to 3,000 mm, Ventiflex ducting comes in six special qualities for different applications.

Comprehensive Quality Control
The largest company in its field, Protan retains control over the entire production process to ensure the highest quality ventilation ducting. The company has its own weaving mill and coating factory, which are both certified according to ISO 9001 and 14001 quality assurance standards. Protan weaves and thoroughly tests its own special webs, which are coated with a PVC coating designed exclusively for use in ventilation ducts. Ventiflex ducts are then manufactured at the company?s prefabrication unit with the aid of specially-designed automated machinery.
