Key Specifications/Special Features:
Introduction:“SuLong” positive ventilation hose is constructed with a fire resistant anti static collapsible PVC coated polyester fabric which complies with the requirements for electrical resistance and fire resistance as tested by the MA centerIt is manufactured in a selection of grades to match the strength specifications required by customer“SuLong” positive ventilation hose has four types: lay flat type, framework type, spiral type and special-shaped and is available in standard sizes from 3m to 200m1. Durable and stable, anti-flaming and anti-static2. Smooth surface and low wind resistance by adoption of the thermal sealing technology3. Excellent tensile strength, overlarge air volume and extra long-distance air supply4. Low expansion rate and slight expansion and no deformation of the air duct in high air pressure ventilation due to the extremely low elasticity of the fiber5. Lighter materials, smaller thickness and higher strength of air duct body6. Easy installation, maintenance and repair7. The air ducts with special shapes can be produced according to customers' requirements, such as, T-piece air duct, Y-piece air duct, switching air duct, elbow, air duct, concentric reducer and more8.
