The Flow Rate of the gas determines the diameter of the silencer. This will allow the gas to safely pass through without eroding the acoustical packing or regenerating noise. The noise reduction necessary to achieve governs the silencer length. A Ventx Silencer uses a combination of diffuser design as well as an absorptive core section. The gas and noise enters the silencer through a multi-hole diffuser. Here, it is permitted to expand through many holes into the expansion chamber. The diffuser also provides a frequency shift to higher frequencies. These are best attenuated by the absorptive section. The gas then passes through this absorptive section. This consists of perforated flow passages surrounded by dense long strand fibreglass acoustical packing providing a broad range of attenuation in the mid to high frequency ranges.

Ensuring the perfect silencer for your needs
At Ventx, we configure your silencers using bespoke solutions and advanced computer software. This personalised design process is a necessary component when it comes to meeting current legislation.
In general terms, the silence configuration involves looking at the flow rate of the gas. This determines the necessary diameter of the silencer in order for the matter to pass through. This is whilst avoiding erosion of the acoustical packaging, and without regenerating noise. The level of noise reduction you desire determines the length.
There are different kinds of silencers to choose from. This includes those such as gas ejector silencers, direct line silencers, plus vent discharge silencers as well as control valve silencers. Gas ejector silences reduce any noise created by hydrocarbon gas or steam. Direct line silencers use absorption as opposed to pressure variation. People often use them along with compressors. You can get this either as a whole unit, or as an acoustic core. You then insert this into your existing pipework.
The experts who know all about silencer configuration
With Ventx, our final option of silencers combines a diffuser design with an absorptive core section. The result is that the gas and noise enter the silencer through a multi-hole diffuser. This then expands through the many holes into the expansion chamber. Additionally, it provides a shift into higher frequencies. This means that they are better attenuated by the absorptive area. Lastly, this section consists of perforated flow passages. Dense long strand fibreglass acoustical packing surrounds these. This offers a broad range of attenuation from the mid to high frequency range.
