Dampers

Technical data 

 

In this table it is given, for each air flow and inlet pressures from 100 to 1000 Pa, the Sound Pressure Level in dB(A) due 
to the noise radiated in the circular damper. To obtain these values we have assumed attenuation in the outlet duct, the 
diffuser and the room of 10 dB/Octave.
