3.2 Sound Pressure Level
The sound pressure level emitted by the BFS-i06 strongly depends on the installation, operating point, and
rotational speed. It is recommended that customers measure the sound pressure level after installation of the
fan in their setup during typical operation.
Figure 12 shows the sound pressure levels measured at Levitronix
®
. The fan was installed at a height of about
2 m above ground into a closed duct system. Measurements were taken based on Semi S2 guidelines, i.e.
1 m traversed from the setup at a height of 1.2 m and 1.5 m above ground.
