To effectively reduce and control the noise from various blowers, including Roots blowers, air compressors, axial flow exhaust fans, and centrifugal ventilators, our company addresses the noise sources of these blowers, which often have more than one frequency spectrum value. Depending on the different noise intensity, generation mechanism, and transmission paths, the requirements for noise reduction vary. To this end, our factory has adopted targeted design, creating a series of silencers that, after being used by numerous manufacturers, have demonstrated excellent noise reduction performance.
