Overview

In large-scale infrastructure projects like tunnels and subways, ventilation systems are the "breathing system" that safeguards the lives of construction workers and ensures smooth progress. Our newly launched 2500mm ultra-large diameter fire-resistant tunnel industrial ventilation hose is designed specifically for these extremely demanding industrial environments. More than just a hose, it's an efficient, reliable, and indestructible mobile ventilation solution.

With an astonishing 2500mm (2.5m) diameter, this hose meets the critical need for massive airflow during tunneling, rapidly exhausting dust, smoke, and hazardous gases while simultaneously delivering fresh air. Its core value lies in its exceptional fire-retardant properties, maintaining structural integrity in high-temperature, open-flame environments, saving valuable time for evacuation and fire rescue efforts.

Product Features

Excellent Flame Retardancy: The fabric itself does not support combustion and extinguishes immediately upon removal of flames, effectively preventing flames from spreading along the pipe.

High Temperature Resistance: It can operate for extended periods in environments ranging from -40°C to +100°C and withstand brief high-temperature shocks without melting or dripping, preventing secondary damage.

Compliant with International Standards: This product meets or exceeds multiple international fire protection standards, ensuring reliability at critical moments.

Large Diameter:

Extremely High Ventilation Efficiency: A single hose delivers exceptionally high air flow, rapidly ventilating deep within the tunnel and maintaining fresh air.

Wide Coverage: Reduces the number of ventilation ducts, simplifies system architecture, and reduces installation and maintenance costs.

Suitable for Large Equipment: Perfectly matches the high airflow requirements of equipment such as large tunnel boring machines.
