-- Steady & Reliable Manufacturer --
This fabric is a specialized, lightweight, and highly flexible PVC-coated polyester material engineered for the construction of temporary and permanent ventilation ducting (lay-flat tubing). The material features a smooth internal surface to minimize airflow friction and reduce energy consumption. It is formulated for superior tear resistance and maintains high seam strength, essential for withstanding the internal pressure and continuous movement typical of mining, tunneling, and heavy construction environments. The fabric is often required to be fire-retardant (FR) and anti-static for safety compliance.
Pioneering Textile Innovation with Two Decades of Excellence
High-quality flex banners, PVC films for outdoor advertising and commercial displays
Functional fabrics for sports equipment, outdoor gear, and recreational products
Durable materials for building wraps, temporary structures, and architectural applications
Specialized textiles for vehicle covers, transportation equipment, and automotive applications
Mining and Tunneling Operations: Essential tubing for delivering fresh air or exhausting contaminated air from deep worksites.
Construction Site Air Conditioning: Flexible ducts for moving heated or cooled air into enclosed work areas.
Industrial Fume Exhaust: Temporary flexible ducting for the removal of welding fumes, dust, or solvent vapors.
Aircraft Ground Support: Flexible conduits for supplying cooled or heated air to parked aircraft cabins.
| Characteristic | Value Range / Standard |
| Fabric Weight Range | 550GSM−750GSM (Lightweight) |
| Tear Resistance | >150N/150N |
| Air Permeability | <0.5 CFM / ft2 (High Airtightness) |
| Fire Retardancy | Available (FR Additive) |
| Weld Seam Integrity | >90% of base fabric strength |
| Flexibility | High (Suitable for tight coiling) |
The choice of duct fabric hinges on the safety requirements of the operating environment (e.g., presence of explosive dust or flammable gases).
Safety Specification: For mining or hazardous areas, FR (B1/NFPA 701) and Anti-Static certification are non-negotiable and must be specified.
Duct Diameter: Ensure the material GSM and inherent stiffness are compatible with the final duct diameter (smaller ducts require more flexible material).
Abrasion: For ducts that are dragged or subjected to high friction, choose a heavier 750GSM option for longevity.
We focus on specialized calendering for the smooth internal coating and optimal welding performance.
Surface Quality: Internal surface finish is inspected to guarantee a low-friction profile, minimizing energy loss during air movement.
Roll Customization: We supply the fabric in narrow widths and high-length rolls, which is preferred by duct manufacturers for long, continuous production runs.
Certifications: Full documentation for any specified FR or Anti-Static compliance is provided, essential for industrial customers.
Q: Can this fabric withstand negative pressure (suction) applications?
A: Yes, the strong, low-stretch polyester scrim provides sufficient structural integrity to prevent collapse under standard negative pressure (suction) used for exhaust ventilation.
Q: Is the material available in highly visible colors?
A: Yes, it is commonly supplied in highly visible colors (e.g., Yellow, Orange, Red) with UV resistance for safety and easy identification in dark tunnels or construction sites.
