A certain number of sound-absorbing sheets are arranged in the large-size air duct to form a muffler with multiple flat muffler channels in parallel, which is called a tube-type muffler. It has a film thickness of 50mm, a film thickness of 200mm, and a film thickness of 100mm. The chip muffler has a simple structure, excellent mid- and high-frequency noise reduction performance, low airflow resistance, and a wide range of applications. It can be applied to pipelines with air volume from 750m3/H to 8000OM/H.
