Wire spiral spring steel, profile Ω PVC wear, rings tested in strand steel coated PVC.
Size range from 150 to 2.400 mm diameter with all intermediate sizes, pitch spiral 30/50/75 special and standard 150mm.
The use of a highly resistant fabric and the constructive structure allow the realization of large diameters suitable for use in installations of suction and discharge under most extreme conditions. With high values of pressure or radii of curvature very accentuated, the possibility of realizing a spiral with a pitch close may be the solution.

Special components are realized by cutting the fabric through a plotter. All special pieces, from “Y” to “T” branches as for the Branches and Curves, with any radius of curvature, or the reductions for the connections with other diameters, are tailored with the maximum attention to the quality of the final product and in compliance with the executive designs.

Flexible and PVC-coated fabric specially designed for forcced ventilation that can be used for high-pressure ventilation in severe mining and tunnelling conditions. Connection with the patented Easy-Joint system
Connection types:

  • patented Easy-Joint system
