Tunnel ventilation hose adopts high density polyester with steel wire as the support. It widely serves in farm, basement, industry, power plant, tunnel and many other applications for ventilation.
Tunnel Ventilation Duct Structure
Tube: High density polyester weave coated PVC on both sides
Reinforcement: Steel wire
Cover: PVC strip
Temperature: -32℃ to 80℃ (-90℉ to +176℉)
Application: Used as ventilation widely serves in airport, tunnel and basement for waste gas and fume exhaust, air condition, light duty dust extraction and air movement.
ZJ Hose Ventilation Hose Our high-quality ventilation hose is designed for efficient air movement. This portable, flexible solution is constructed from polyester fabric with a PVC coating, reinforced by a steel wire spring helix to deliver enhanced structural integrity.
In addition to protecting the wire helix, an external wear-strip safeguards the hose from physical abrasion when dragged across rough surfaces, extending its service life.
Flexible plastic ducting is engineered specifically for air transfer. Beyond general ventilation, it serves as AC ducting for portable air conditioners, duct cleaning, and other applications. With a working temperature range of -20°C to 80°C, it is perfectly suited for both cold and hot air conveyance.
