薄膜通风管优点
Advantages of thin film ventilator
1，风量大，风力输送助力小，最高风速可达100米每秒；可以在薄膜通风管上任意开孔，达到风量均匀，温度控制精准，提高舒适性；耐腐蚀，对大多数酸碱，氨气等不敏感；塑料薄膜风管可以用水清洗，拆装方便；系统由特殊薄膜生产而成，重量极轻，约为传统金属风管系统的1/20，特别适合用于屋顶无承重能力的场所；薄膜通风管不会产生振动，静音。
1, the wind volume is large, the wind power is small, the maximum wind speed can reach 100 meters per second; the air volume can be open on the film ventilation tube, the air volume is uniform, the temperature control is accurate, the comfort is improved; the corrosion resistance is not sensitive to most acid base, ammonia and so on; the plastic film wind pipe can be washed with water and disassembly is convenient; the system is special. The thin film is made with light weight, which is about 1/20 of the traditional metal duct system. It is especially suitable for the place where the roof has no load bearing capacity; the film ventilator does not produce vibration and mute.
缺点
shortcoming
仅能做正压通风，不能做负压通风吸气；不耐高温，遇到电焊火心会烧穿。
Only positive pressure ventilation can be done and negative pressure ventilation can not be done
