The sewn HVAC & ventilation hose is particularly suitable for heavy duty fume and air pushing/extraction purposes. The wide range of materials, including insulated versions, make this product suitable for building, tent, machinery, mining and industrial ventilation purposes. The correct choice of materials and construction type make this product suitable for permanent and mobile installations.
DuraSpiraflex ducting, is typically assembled using a combination of single, two or three-ply fabrics, sewn onto a metal spiral, which is then covered with an abrasion resistant scuff strip, creating a highly durable and flexible duct.
DuraSpiraflex ducts are constructed using hot galvanised or spring steel wire, which is pitched to suit the desired task, where negative air pressure (usually air suction) requires a much tighter spiral arrangement when compared to pushing ducts. Insulated products can further increase the efficiency of hot & cold air transportation. It is the accurate selection of all base materials, in combination with specialist assembly techniques, that make these products outperform conventional alternatives, in terms of quality and longevity.
DuraSpiraflex ducts are available in diameters of up to 2 meters and lengths of 40 meters. Layflat ducts are used in combination with structured products and baloon into shape when filled with air (pushing hot or cold air).
