复合风管是由多种混合材料加工制作成的，包括酚醛、玻镁等风管，是20世纪7、80年兴起发展起来的传统风管，但在一些特定的场馆，越来越凸显出它的弊端，最突出的就是清洗问题，纤维布袋送风系统是一种由特殊纤维织成的柔性空气分布系统是替代传统送风管、风阀、散流器、绝热材料等的一种送出风末端系统。 它是主要靠纤维渗透和喷孔射流的独特出风模式能均匀线式送风的送出风末端系统。非常便于清洗。
Composite air duct is made of a variety of mixed materials, including phenolic resin, glass magnesium and other air ducts. It is a traditional air duct that rose and developed in the 7th and 80th years of the 20th century. However, in some specific venues, its disadvantages are more and more obvious. The most prominent problem is cleaning. Fiber bag air supply system is a kind of flexible air distribution system woven from special fibers, which replaces the traditional air supply pipes Air valve, diffuser, thermal insulation material, etc. It is a kind of air supply terminal system which can supply air uniformly and linearly by the unique air supply mode of fiber penetration and orifice jet. Very easy to clean.
