Pneumatic Mufflers are used to quietly exhaust compressed air.

Compressed air systems and air blowing are usually the sources of loud, sudden noise in factory or plant settings. Air blowing causes a sudden noise when the compressed air system releases the air. The loud noise is generated by the air turbulence created when the air expands freely. Controlling turbulence reduces noise. There are two sources of noise when compressed air is used: first, noise from the air blasts used for cleaning, cooling, transport, and sorting; second, and generally more aggressive sounding, the noise from the venting valves used in fluid power. The solutions required to control turbulence and reduce noise from these two sources are very different. Today we’re presenting a solution you can use to reduce noise from venting valves: pneumatic mufflers.
