Glass fiber reinforced plastic fan is a noise reduction equipment, when the fluid machinery is running, it will produce some noise, and the noise is reduced by sound insulation equipment, and it is also the preferred equipment for noise reduction.
隔音箱玻璃钢风机是一种降噪设备，在流体机械运转时，会产生一些噪声，而噪声就用隔音箱设备来降噪，也是降噪首选设备。
Why do sound insulation boxes play a role in noise reduction?
为什么隔音箱会起到降噪的作用？
The original sound insulation box is made of sound insulation board, sound absorption cotton and other silencer materials, according to the size of the fiberglass centrifugal fan to determine the size of the soundproof box frame, so the fiberglass centrifugal fan than the soundproof box fiberglass fan covers a smaller area.
原隔音箱是采用隔音板、吸音棉等消音材料制作，依照玻璃钢离心风机大小确定隔音箱框架尺寸，所以玻璃钢离心风机比隔音箱玻璃钢风机占地面积要小。
The sound insulation board of the fiberglass fan can be selected from raw materials (FRP, 304, galvanized, etc.), and the sound-absorbing cotton is: ordinary cotton, thickened cotton, flame-retardant cotton, etc., so the cost budget and raw material selection are also key.
隔音箱玻璃钢风机的隔音板可选原材（FRP、304、镀锌等），而吸音棉有:普通棉，加厚棉，阻燃棉等，所以成本预算与选原材也很关键。

若采购隔音箱玻璃钢离心风机，那它有哪些好处？
When used in residential areas, it can reduce the probability of being complained, run 55~60hz at night, it will not affect the normal rest of the people around, and the ventilation system can operate normally.
在居民区使用，可以减少被投诉几率，夜间运行55~60hz，是不会影响周围人们正常休息，可正常运转通风系统。
If used in biological deodorization and sewage treatment plants, it can prevent odor discharge twice, and it is also a necessary fan equipment for deodorization.
若使用在生物除臭及污水处理厂，它能进行二次阻止臭气排放，也是除臭必选的风机设备。
