What's a Buna bag duct

The Buna Bag Air Duct is a flexible air distribution system made of special fibers, which replaces the traditional sheet metal air supply duct, air valve, diffuser, insulation material and other air outlet systems. It is a system with unique air outlet, which mainly relies on fiber penetration and jet hole to distribute air uniformly in a linear manner. As far as production is concerned, it looks like a big cloth bag, so in China, this system is usually called cloth Air Duct, bag air duct, Fabric Air Duct, fabric air duct, etc. . Of course, this is only a visual term, because the bag air duct system is not just an air duct, it not only plays the role of airflow transmission, but more importantly, as a wind supply device, the design of Fiber Cloth Air Duct directly affects the air supply, refrigeration and heating effect of the whole space.
