Tunnel Ventilation Duct Hose


Tunnel Ventilation Duct Hose is a high quality air ventilation ducting for air transfer. This portable flexible duct hose is made from polyester fabric that coated with PVC. The body of this flexible air ducting hose has a spring steel wire helix reinforce. Its helix is made to provide the flexible ducting with an enhanced physical frame. In addition to the protection of the wire helix, its external section of the hose is protected by a wear-strip. If your application involves this air ventilation ducting being dragged across the ground or other surfaces, this wear-strip will guard the body of the hose from most physical abrasions.

Underground ventilation duct is specifically made to transfer air. In addition to general air ventilation, PVC ventilation ducting can serve as air conditioner ducting hose for portable AC and duct cleaning. The flexible air ventilation duct has a working temperature range of -20 to 80℃, which makes it perfectly suitable for transferring both cold and hot air.
