Overview

This revolutionary ventilation hose is designed specifically for underground construction environments such as tunnels, subways, and mines. Its unique "lay flat" design allows it to be flattened and folded like a fire hose when not in use, significantly saving storage and transportation space. When ventilation is in progress, it rapidly expands into a regular circular tube shape due to internal air pressure, efficiently delivering fresh air. It is a key piece of equipment for ensuring a safe working environment in tunnels and improving construction efficiency.

Product Advantages

Space-saving, extremely low transportation and storage costs

Traditional rigid ducts or round hoses are bulky, requiring significant space and vehicle resources for transportation and on-site storage. Our flat ducts can be completely flattened when not in use, reducing their volume to only one-third to one-fifth of their inflated state. A single truck can transport several times the volume of traditional duct, significantly reducing logistics costs and on-site storage requirements.

Lightweight and easy to install, significantly improving work efficiency

Made from high-strength, lightweight composite materials, the product is extremely lightweight. Ducts tens of meters long can be easily transported and laid by a single person, eliminating the need for large machinery. Connections typically utilize simple zippers, Velcro, or flanges, making installation and removal extremely fast, enabling rapid response to tunnel excavation advances and saving valuable labor and time.

Excellent Structure and Durability

Despite its thinness, its flat structure provides excellent compressive strength, making it less susceptible to blockage by debris or equipment commonly found in tunnels. The pipe body is woven with high-strength polyester fiber as the skeleton and covered with a special PVC coating inside and outside. It has the characteristics of wear resistance, tear resistance, moisture resistance, and flame retardancy. It can adapt to the harsh environment of humidity and dust in the tunnel and has a long service life.
