≤
59.2 dB(A)
Note
When two air/brine
collectors (on VWF 157/4,
VWF 157/4 S1 and VWF
197/4) are running at the
same sound power level at
the same time, the total
sound power level result is
3 dB(A) higher.

63.7 dB(A)
Note
When two air/brine
collectors (on VWF 157/4,
VWF 157/4 S1 and VWF
197/4) are running at the
same sound power level at
the same time, the total
sound power level result is
3 dB(A) higher.
