1. It is deformation from slice-type resistive muffler. In order to improve the noise elimination performance of high frequency, it is changed into folded plate type from straight slice type to get high sound attenuation with smaller section. It is suitable airflow velocity of 4~8m/s, resistance loss is a littler big than slice type muffler, resistance value ζ≤1.4.
2. It can be used with unit-section, as well two-sections or three-sections, but better for 1~2 section. HY-XZB~A model should be used when it is must located in machine room or higher noise place.
1. Chip-type Dissipative Muffler is that the Tube-type Resistive Muffler adds some sound-absorbing slice. It is applicable to large cross section of duct and large air flow. It divides the straight tube into several small channels, and sound-absorbing slice is straight type, ...
