Silencer retrofits

In addition to resonator silencers, special silencer baffles can also be tuned to low-frequency sounds. The “humming noises” perceived as pollution in the neighborhood (e.g. the ignition frequency in an engine or the flame noise of a boiler’s burner) can thus be significantly reduced.

Due to small volumes and partly negligible pressure losses, sound problems can be solved with minimum effort using Nießing’s special developments.
