Overview
Our ventilation hose for tunnel ventilation projects is a high-performance ventilation duct specially designed for harsh environments such as tunnels, underground projects, mines, and chemical workshops. This product is made of high-strength PVC-coated fabric, featuring excellent chemical resistance, wear resistance and anti-aging performance. It can operate stably for a long time under complex working conditions such as humidity, high temperature and corrosive gases.
The flat-laid design enables the air ducts to be folded and stored when not in use, saving storage and transportation space. At the same time, it is easy to install and can be quickly unfolded for use. This air duct is suitable for positive pressure air supply ventilation systems and is widely used in tunnel construction, underground engineering ventilation, industrial waste gas emission and other fields.
