Reactive Silencers

Additional Details

Reactive silencers are used to reduce low-frequency noise which is very common in low-speed equipment such as, low-speed diesel engine, vacuum pump and sometimes twin lobe blowers. In reactive silencers, no absorptive material is used. The low-frequency noise is nullified by the reaction by the process gas inside the silencer. These are resonated type or multi-chamber construction or a combination of both. The general limitations of reactive types are a reasonably high-pressure drop across the silencer and its unpredictable performance for high-frequency noise reduction. We also offer a mixture of reactive and absorptive silencers depending on the sound made to achieve the desired noise level performance
