The sound power level generated by ducted fancoils (FCX -PO)
depends on fan speed and on the point of operation reached
according to pressure drop.
The following diagrams can be used to obtain the sound power
level (weighted A), expressed in dB (A) in relation to the rele-
vant curve, according to air flow and available static pressure
values.
