Silencer Configuration

The Flow Rate of the gas determines the diameter of the silencer so that the gas can safely pass through without eroding the acoustical packing or regenerating noise. The silencer length is governed by the degree of noise reduction to be achieved. A Ventx Silencers uses a combination of diffuser design and an absorptive core section. The gas and noise enters the silencer through a multi-hole diffuser where it is permitted to expand through many holes into the expansion chamber. The diffuser also provides a frequency shift to higher frequencies, which are best attenuated by the absorptive section. The gas then passes through this absorptive section, which consists of perforated flow passages surrounded by dense long strand fiberglass acoustical packing providing a broad range of attenuation in the mid to high frequency ranges.
