How Does Duct Silencer Work

Conic flow tubular silencers are available for silencer applications including low frequency silencers having acoustic performance specifically engineered for the 63 hz 125 hz and 250 hz octave bands.

How does duct silencer work.

Standard and custom duct silencers. With the silencer in place the pressurized gas behind the bullet has a big space to expand into. When assembling larger silencer components it may be easier to slip the duct extension on with the inlet or outlet facing upwards. The size can differ depending on the frequency of the sound being controlled.

The combined interior diffuser cone and exterior square. These can be fabricated as two separate standard silencers and constructed to fit the structure you are working with. So the pressure of the hot gas falls significantly. As the silencer contains air pockets this can help to trap the air inside the silencers.

A duct silencer can be engineered specifically for use in clean environments such as hospitals. D duct acoustic diffuser silencers are appropriate for use on axial fan systems. Low frequency silencers are engineered specifically for 63hz and similar octave bands. A silencer screws on to the end of the barrel and has a huge volume compared to the barrel 20 or 30 times greater.

Do not use any fasteners at this time as some movement may be needed to align the components see figure 1 2. When the bullet finally exits through the hole in the silencer the pressure. But it s also possible to have silencers that don t have any filling. The linings in the silencer don t shed particles into the air.

For projects that necessitate silencers that are larger than the maximum standard dimensions 48 x 48 we carry rectangular duct silencers. The way duct silencers work is by trapping the sound waves that meet it allowing the waves to fill the silencer located inside the fitting.
