Wideband precision manufacturing muffler Texas Feiyu Sales Hotline: 13969272212 

 Broadband muffler, including both ends of the interface and with the wind into the air interfaces of the duct, the duct interior with perforated panels and sound-absorbing material, perforated plate consists of a set thickness, perforation rate, not the same diameter and pitch single perforated plates. Compared with existing technologies, the present invention uses two kinds of resistive and resonant acoustic silencer constructed to control, low-frequency noise-based, taking into account the high-frequency noise, which noise reduction is good, with the various types of ventilation systems high practical value.
