Engineering Ventilation Duct φ1500

🌀Engineering Ventilation Duct φ1500 Product Overview

The Positive Pressure Ventilation Duct φ1500 is specially engineered for ultra-large tunnel sections, deep mining shafts, and urban underground projects requiring high-capacity airflow. Each standard section measures 10 meters in length and is constructed from high-strength double-sided PVC-coated knife-coated fabric, delivering excellent pressure resistance, flame retardancy, and weather durability.

As one of the largest diameter ventilation ducts commonly used in industrial settings, the φ1500 duct is compatible with high-power blower systems and ideal for long-distance ventilation with high air volume demands and stringent safety requirements. This product is manufactured strictly following Chinese national and industry standards, without involving any foreign certification systems.
