Hangzhou Dongxing Telecommunication Material Co.,Ltd is one of the professional China black color flexible ventilation duct, made in china, long service life manufacturers and suppliers, and equipped with a productive black color flexible ventilation duct, made in china, long service life factory and company, welcome to contact us.
“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 center
It 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 200m
1. Durable and stable, anti-flaming and anti-static
2. Smooth surface and low wind resistance by adoption of the thermal sealing technology
3. Excellent tensile strength, overlarge air volume and extra long-distance air supply
4. 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 fiber
5. Lighter materials, smaller thickness and higher strength of air duct body
6. Easy installation, maintenance and repair
7. 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 more
8. Environment-friendly products
