This flexible duct is made of lightweight materials. It can be quickly deployed in tunnels and easily carried and installed by a single person, significantly reducing labor intensity. It excels in situations where emergency ventilation or temporary ventilation routes need to be quickly established. Despite its lightweight, its PVC coating provides the necessary durability and weather resistance. It is an ideal ventilation system for tunnel rescue, emergency construction, and short-term operations.

Use high quality raw materials to ensure product quality;
Being engaged in the field of ventilation system for more than 30years, have rich experience in ventilation design;
Cooperate with several research institutes and have the latest technology;
Several automatic ducting welding production lines with a monthly output of 20,000 flexible ventilation tubes with assured batch order lead time;
PVC ventilation tubes are available in custom sizes to ensure a perfect fit for your requests;
The spiral ventilation duct is coupled with zipper and Velcro. The extra fabric on which the zipper/Velcro is sewed is welded to the flexible duct body to ensure that there are no sewing needle eyes throughout the ducting, reducing air leakage.
