The selection of the best suited silencer is based on:
For noise remediation requirements different than those indicated in the diagram, we can provide silencers’ dissipative elements with different thickness.
For an air duct with flow capacity of 20.000 m 3 / h and with maximum head loss of 10 mm. H2 0, Figure 3 diagram indicates a silencer type S202/100 (BxH = 800 x 1000 mm.).
If the noise abatement required is greater than 25dB at the octave frequency of 250 Hz then Figure 5 indicates the usage of a silencer with L = 1500 mm.
