BENEFITS • Self-supporting bottom inlet provides energy dissipation and modification of the noise spectrum for easier attenuation

• Provides back pressure required for optimum valve performance and size

• Minimizes shell noise radiation and noise leakage by slowing flow velocity

• Multiple flow tube surrounded by acoustic packing absorb and attenuate high frequency acoustic energy as modified by the inlet diffuser

APPLICATIONVent Silencers suppress noise generated by the rapid release of gas or steam under high pressure to atmosphere by shi�ting the noise spectrum from a low frequency to a higher frequency range which is more easily attenuated. Typical applications are:

• Boiler Startup and Shut Down Systems • System Purge

• Control Valves • Centrifugal Compressors

• Steam Ejectors and Vents • Blowdown Systems
