Engineering Positive Pressure Ventilation Duct φ1200-10

🌀 Engineering Positive Pressure Ventilation Duct φ1200-10 Product Overview

The φ1200-10 Positive Pressure Ventilation Duct is specially engineered for high-volume positive pressure ventilation systems. Ideal for large-scale tunnels, underground mines, comprehensive utility tunnels, and other heavy-duty engineering projects. This industrial-grade air supply hose is made of high-strength polyester fabric coated on both sides with PVC knife-scraped layers, offering excellent tear resistance, flame retardancy, anti-static properties, and pressure durability to ensure long-term stable operation in harsh environments.

With an extra-large diameter of 1200mm and a standard length of 10 meters per section, it significantly improves airflow efficiency, reduces the number of joints, and enhances overall system airtightness.
