1,Mufflers Type WX, consisting of zincification(or allumium alloy) perforation plates. They have better effect in wider sound fequency scope, because of different perforation and double-layer perforation. This muffler can eliminate noise in low frequency; in middle frequency.
2,The mufflers, are simple structure and small friction coefficient, work without dust and oil, endure of vapour and high temperature impact, widely used in contioners and ventilating pipes.
3,perforation muffler has small resistance loss. Checked, the muffler has a resistance 0.7-3mmH20 at the wind speed.
