How Does Duct Silencer Work

Low frequency silencers are engineered specifically for 63hz and similar octave bands.

How does duct silencer work.

Do not use any fasteners at this time as some movement may be needed to align the components see figure 1 2. Standard and custom 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. But it s also possible to have silencers that don t have any filling.

The duct extension should slip onto the silencer component 2 or until the lock forms butt together. When the bullet finally exits through the hole in the silencer the pressure. D duct acoustic diffuser silencers are appropriate for use on axial fan systems. For projects that necessitate silencers that are larger than the maximum standard dimensions 48 x 48 we carry rectangular duct silencers.

The size can differ depending on the frequency of the sound being controlled. These can be fabricated as two separate standard silencers and constructed to fit the structure you are working with. As the silencer contains air pockets this can help to trap the air inside the silencers. The combined interior diffuser cone and exterior square.

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. The basic principle is to transform the round cross section of the duct into a slim rectangular one while maintaining the area of the cross section because my intuition told me that reducing the duct size will make my a c less efficient and ultimately perhaps even damage it. With the silencer in place the pressurized gas behind the bullet has a big space to expand into. The linings in the silencer don t shed particles into the air.

When assembling larger silencer components it may be easier to slip the duct extension on with the inlet or outlet facing upwards. How do the duct silencers work.
