SILENCERS TYPE NAS
Specification:
Type NAS residential/critical silencers are absorptive silencers and are in general used for attenuation (approx. 30 dB (A)) in the middle and higher frequencies.
The silencers can be mounted in both horizontal and vertical way. Recommended gas speed max. 60 m/s, maximum temperature 600 °C.
In general, the silencers are manufactured in mild steel (S 235 JR G2) and provided with a black heat resistant silicon coating. The silencers are optionally also available in other material such as stainless steel 304 and 316.
Attenuation silencer (measured on a 6” system):
The pressure drop of the silencer is depending of the exhaust flow (gas velocity) through the silencer.
With the help of below mentioned formula it is easy to calculate the pressure fall.
If required we will give additional detailed information.
In case of strict noise level and/or limited dimensions, it is often not possible to work with a standard silencer.
The know-how of acoustics and flow dynamics of the technical department , enables them to design a silencer for a specific sound- source, which results in a optimum noise reduction for that specific situation.
Pressure drop calculation:
Combination of air-inlet and outlet silencer and double exhaust silencers for specialized compressed air systems
