Safety silencers

The noise from compressed air valves is extremely hazardous, but equipping valve discharge ports with silencers often causes operational disturbances. Silvent silencers have integrated warning indicators. The technology basically entails that the silencer itself sets the optimal combination of flow capacity and noise suppression thanks to the dynamic internal filter, which subsequently minimises operational disturbances and eliminates clogging.


Fitting the exhaust ports of pneumatic valves with silencers is a simple measure to take, and the advantages are many and well documented:

  •  Reduced risk of hearing problems such as tinnitus, hearing loss, echoing and hypersensitivity to sound
  • Better working environment
  • Improved performance clogging a well-known problem with conventional silencers is that, sooner or later, the filter – the diffuser – becomes clogged with impurities and causes:
  • Costly machine stoppage
  • The operational disturbance that is difficult to pinpoint
  • Risk of explosion. This has resulted in many production technicians removing silencers to avoid problems of this sort.
  • Quite simply, the advantages of noise abatement have had to take a back seat to the practical problem of clogging.

Warning indicators offer a solution Years of research have enabled Silvent to develop a new, unique and patented series of safety silencers with built-in warning indicators. Basically, the design allows the silencer itself to determine and set the optimal combination of flow capacity and noise reduction through the use of a dynamic inner diffuser. A reliable warning system also indicates that the silencer is about to clog.

Using safety silencers of this type means that you:

  • Minimise costly machine stoppage
  • Receive a warning before problems arise
  • Reduce the risk of industrial accidents
  • Allow prioritisation of noise control measures
