Silencers absorb and reduce noise emitted from machinery and other sources for the safety of everyone exposed and for regulatory compliance. Silencers may vary in terms of their physical location relative to the item being silenced. For example, inlet silencers mount on the intake side while exhaust silencers mount on the outlet or exhaust of the device. There are many applications for silencers such as noise reduction for industrial engines and turbines, air or gas compressors, vacuum pumps, or valves. Common sources of noise at industrial sites include restrictions in piping (e.g. relief valves, control valves, orifices, and other locations), excessive velocity flow in pipes, engines/turbines and compressors/blowers.
Silencers are undoubtedly required in many settings, such as factories, to bring the noise level to manageable levels. However, there are many situations where liquids and gases have to be separated and re-circulated or discharged. Often, this separation process causes noise that may be at unacceptably high levels. For example, during water separation in generators, the noise created by water splashing at the exhaust outlet can be unacceptably high. In such cases, combined silencer separators have to be installed.
