Our company’s muffler/silencer products of ventilation has more reasonable structureand more advanced process after years of development and production. And all have achieved full mechanized production.
It has unique design, advanced process, refining process. The performance indicators have reached the national standard GB/T 4760-1995< Measurement procedures for silencers> and industrial standard HJ/T 16-1996<Silence for ventilation>.
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.
