Ducts: Highest Quality for Efficient Air Transport

As important components for our plants flexible and rigid air ducts, so-called folding ducts and spiral ducts as well as fiberglass ducts are part of our product portfolio.

In addition to fabrications for tunnelling we offer special qualities for coal mining.

By the use of special textures and coatings firmness is achieved that allows operation pressures up to 10,000 Pa (duct diameter 800 mm). The leakage losses are reduced to < 1 %.

The low air resistance and the minimized leakage loss of the duct fabric (nearly = zero) are achieved by the use of synthetic polyester fabrics in combination with vacuum sealed and airtight PVC coatings.

Depending on the case of application blowing ducts, also referred to as folding ducts, are produced in diameters from 300 to 3000 mm and in individual lengths up to 300 m per duct piece. CFT is exclusive trader of its partner Schauenburg Tunnel-Ventilation in Poland and CIS.
