Mining Negative Pressure Ventilation Duct φ800-10

Mining Negative Pressure Ventilation Duct φ800-10Product Overview

The Mining Ventilation Duct φ800-10 uses a single-piece 4m × 4m knife-coated fabric as the main material, formed in one go to reduce seams and enhance overall airtightness and pressure resistance. It is specially designed for underground main ventilation negative pressure systems, perfectly suitable for deep extraction, long-distance ventilation, and high-power exhaust fan applications.

Made from high flame-retardant and high-insulation base fabric, it features excellent anti-static and abrasion-resistant properties, meeting stringent safety standards for underground coal mines.


Mining Negative Pressure Ventilation Duct φ800-10 Key Advantages

  • Single-piece 4×4m fabric forming: fewer seams, higher strength, superior resistance to negative pressure suction

  • Surface coating with excellent flame retardancy: scratch-resistant and anti-aging

  • Suitable for heavy-duty ventilation scenarios: enhanced deformation resistance under negative pressure

  • Supports quick installation: compatible with quick connectors, zippers, or steel ring fastening

  • Maintains shape integrity: no deformation or collapse to ensure stable negative pressure system operation
