Engineering Ventilation Duct φ1000

🌪️Engineering Ventilation Duct φ1000 Product Overview

The Positive Pressure Ventilation Duct φ1000 is an extra-large diameter air supply hose specially designed for large-section tunnels, deep mine ventilation, underground utility corridors, and large industrial facilities.
With a diameter of 1000mm, it is compatible with ultra-high air volume positive pressure fan systems, delivering superior ventilation efficiency and a wider application range.

Manufactured from high-strength PVC-coated polyester (knife-coated fabric), this duct offers exceptional flame-retardant, tensile, tear-resistant, and anti-static performance. It is ideal for harsh environments with high dust, high humidity, and heavy loads.
