The 730GSM Heavy-Duty Anti-Static FR Mining Tunnel Ventilation Flex Duct is a premium ventilation solution engineered specifically for the demanding conditions of underground mining and tunnel projects. Designed to deliver reliable airflow while addressing critical safety concerns, this anti-static flex duct combines robust construction with industry-leading protective features. Crafted from high-grade materials, it stands up to the harsh environments of underground operations, ensuring consistent performance and long-term durability. Whether used in deep mining shafts or large-scale tunnel constructions, this mining ventilation duct is a trusted choice for professionals prioritizing safety, efficiency, and resilience.
This mining tunnel ventilation duct features advanced anti-static technology that effectively dissipates electrostatic charges, eliminating the risk of sparks in volatile underground environments. The specialized treatment ensures continuous static protection, safeguarding both equipment and personnel from potential hazards associated with static buildup.
As an FR (Fire-Resistant) ventilation duct, it meets global safety standards including M1, B1, and NFPA701, providing critical fire protection in enclosed mining spaces. The fire-resistant properties slow flame spread, giving valuable time for evacuation and emergency response in the event of a fire.
Built with heavy-duty polyester fabric, the 730GSM flex duct offers exceptional tensile and tear resistance. Its rugged construction withstands abrasion, impacts, and the physical stresses of installation and daily use in mining tunnels, reducing the need for frequent replacements.
Formulated with high-quality PVC coating and a precision lamination process, this underground ventilation duct exhibits excellent anti-aging properties. It resists degradation from temperature fluctuations, humidity, and chemical exposure, maintaining performance even in long-term underground deployments.
The 730GSM mining ventilation duct features a polyester woven fabric base with a plain weave structure, ensuring uniform strength across the entire duct surface. The fabric is coated with a durable PVC base coat that enhances protection against moisture and environmental damage. The lamination production technique ensures strong adhesion between layers, preventing delamination and maintaining structural integrity. It boasts excellent color fastness, retaining its appearance and performance through extended use. The duct operates effectively within a wide temperature range, adapting to the varying conditions of underground mining sites. Its welding adhesion and coating adhesion are engineered for maximum stability, ensuring the duct remains secure and leak-free during operation.
