Ⅰ.General Introduction :
This type of system is impedance muffler.In the section of resistance, the sound absorption channel is adopted, and the resistance section is a channel of multi cavity expansion chamber, which can ensure the sound attenuation in a wide frequency range.


Ⅱ.Specifications :


Ⅲ. Application :
Mainly used for the aerodynamic noise generated by the low pressure centrifugal fan, the boiler blower, and the exhaust gas.
