Folded Plate Type Impedance Muffler [xb]

Product Description

The muffler can obtain a higher sound attenuation with a smaller cross section and a small resistance loss.

The muffling performance of folded plate muffler is mainly of medium and high frequency, the muffling capacity and pressure loss are greater than that of chip muffler, and the unit length is 900mm
