**Selection Software for Silencers**

Precise, the silencer configurator from Configurator Solutions, works for two types of silencers:

•Vent silencers

•Blowdown silencers

Select type of product based on application area

Configuration: Enter values for fluid, upstream temperature & pressure, specific gravity, atmospheric pressure, downstream temperature, flow rate & noise attenuation to get a list of valid products

Calculation steps:

Select type of product based on application area

**Vent Silencers**Configuration: Enter values for fluid, upstream temperature & pressure, specific gravity, atmospheric pressure, downstream temperature, flow rate & noise attenuation to get a list of valid products

**Calculations:**•Silencer diameter based on Flow Rate

•Silencer length depends on Noise Attenuation required

Calculation steps:

•Velocity limit is set based on continuous, intermittent & occasional service

•Downstream specific volume is calculated

•Actual specific volume is calculated

•Appropriate models are filtered on validating that they fit within velocity limits

Configuration: Enter values for fluid, flow coefficient, specific gravity, orifice throat area, pressurized volume & atmospheric pressure to get a list of valid products
