High Strength Wind Resistant Tarpaulin For Air Duct Wind Sleeve

High-strength tarpaulin for ventilation wind sleeves built on sturdy polyester mesh base, outstanding tensile and wind pressure resistance to avoid deformation under strong airflow in construction and industrial ventilation sites. PVC coating ensures tight air sealing without air leakage to keep ventilation efficiency. Anti-aging and UV resistant to avoid pulverization during long outdoor pipeline layout, tolerating mild corrosion in dusty workshops. Flexible for heat sealing splicing to custom sizes, lightweight for roll transport, widely used for construction exhaust, farm ventilation and factory dust removal ducts.

Tight Air Sealing for Ventilation Efficiency: Formulated with an elite-grade PVC coating layer, this tarpaulin guarantees a perfectly airtight barrier structure. It completely eliminates slow air leakage or pressure drops along extensive pipeline runs, maximizing fan ventilation efficiency and cutting energy costs for industrial site managers.
High-Pressure Structure Resistance: Built upon an ultra-tough, thick 2000D×2000D (9×9) polyester mesh base, the material delivers tremendous wind pressure resistance (2200/2100 N). It maintains a stable, smooth cylindrical airflow pathway under intense high-speed construction and mining exhaust forces without ballooning or deforming.
Heat-Welded Customization & Freight Economy: The flexible composite material is highly optimized for rapid, reliable heat-sealing and hot-wedge splicing to create non-standard, extended custom duct diameters. Despite its high mechanical strength, it remains sufficiently lightweight for rolling up tightly, allowing distributors to reduce bulk ocean freight space and simplify on-site logistics.
