Textile and coating make up a unique fabric and the suspension system makes the duct even stronger.
Textiles
The textiles, which have been developed specially for ventilation ducts, have radial reinforcement to prevent tearing. If a hole should nevertheless occur, our textiles are knitted precisely in order to limit the length of the tear. Protan Ventiflex textiles are also designed to be dimensionally stable so as to prevent expansion under high pressure.
PVC coating
PVC coating on the outside has been developed to withstand damage and mechanical wear, and is thick enough to protect the textile. Internally Ventiflex is designed to offer low flow resistance, which helps save energy. Our unique coating method produces a strong structure and also reduces the risk of delamination. The fabric comes in a colour that reflects light.
The suspension system
This system with its plastic eyelets is also unique and employs a strong continous suspension rib, which runs along the length of the ducting and is welded on. the plastic eyelets contribute to the overall strength of the system. Ventilation ducts in mines and tunnels are exposed to extreme stress, including pressure waves caused by blasting, which put every part of the construction on the test.
Couplings and hooks
Protan have a wide range of components that contribute to the great flexibility and adaptability of the ventilation system.
