PVC Coated Polyester Fabric Tunnel Ventilation Duct Hose
PVC Coated Polyester Fabric Tunnel Ventilation Duct is a high quality air ventilation ducting for applications that involve air movement. This ventilation fan duct hose is produced from polyester fabric that is coated with PVC vinyl. The body of this flexible fan ducting hose is reinforced by a spring steel wire helix. Its helix is made to provide the flexible blower 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 blower 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.
The hose is specifically made for transferring air. In addition to general air ventilation, its can be used as air conditioner fan ducting hose for portable AC, duct cleaning, and more. The flexible air ventilation duct has a working temperature range of -20 to 80 degrees Celsius , which makes it perfectly suitable for transferring both cold and hot air.
