Inline Silencer

Hits : 54   |      

Silencers are used to reduce noise associated with internal combustion engine exhausts, high pressure gas or steam vents, compressors and fans. They attenuate and/or absorb air-born sound waves propagated in a flowing medium. These examples lead to the conclusion that a silencer allows the passage of fluid while at the same time restricting the free passage of sound. They are normally custom-designed equipment.
