Combination silencers


Nießings combination silencers provide high levels of damping across the whole frequency range – while losing almost no pressure. The combination silencers work without any internal components, which exploits all the benefits of minimal pressure loss. The combination of a cavity resonator (designed to cope with a broad range of frequencies) and a porous absorber allows for damping across the entire spectrum from 25 Hz – 8000 Hz. 

Nießing noise damping systems can be integrated not only in pipelines, but also into steel chimneys. They can also be designed and installed directly as self-supporting steel chimney variants.
