The FXS2 series and FXS2a series sieve plate mufflers use copper wire mesh as the sound-absorbing material. This muffler not only has a significant noise reduction effect on the middle and high frequency range of aerodynamic noise, but also has the advantages of good pressure resistance and long life, and its sound attenuation The sleeve can be disassembled, washed and replaced, thereby reducing costs.

FXS and FXSa series mufflers are absorption mufflers that use copper bead sintered cups as sound-absorbing materials, which have a good noise reduction effect on the mid-to-high frequency range of aerodynamic noise.
