Engineering Positive Pressure Ventilation Duct φ1000-10

🌀Engineering Positive Pressure Ventilation Duct φ1000-10 Product Overview

The Positive Pressure Ventilation Duct φ1000-10 (PVC coated fabric) is an industrial-grade flexible air duct designed for high-volume, high-pressure air delivery in demanding environments. It is widely used in tunnel excavation, deep mine ventilation, municipal underground projects, and other large-scale air supply systems.

Made of double-sided PVC coated polyester fabric with a high-density mesh-reinforced base cloth, the duct offers high tensile strength, flame resistance, anti-static properties, flexibility, and oil resistance.
The φ1000mm ultra-large diameter matches high-power ventilation fans, while the 10-meter standard length allows for faster installation and long-distance air delivery connections.
