Note that the sound pressure level is based on open ground conditions and is not a guarantee value. Due to the reflection of the wall and the surrounding environment on the sound, the sound pressure level of indoor installation is usually higher than that of open places.

In order to minimize the sound pressure level of the centrifuge, it is recommended that the centrifuge be installed in the room with low reflection on the surrounding wall and properly maintained.

LwAd: A sound level sound energy level of centrifuge

LpAd: change of A-level sound pressure level of the reflecting plane on the empty ground within 1m of the centrifuge with respect to the declared value: LwAd: KwA=2 dB

LpA: Kpa =4 dB

The noise does not include pounding or tone components, and the sound pressure level at the moment of peak C sound level under full speed operation is below 130dB (C).

Measure the sound energy level when the centrifuge operates with water as the process medium according to EN ISO9614-2. The sound pressure level is determined from the measured sound energy level according to EN ISO11203.

At different locations around the centrifuge, the sound pressure level varies from 1dB to 2dB.

Some operation modes of the hydraulic rear drive centrifuge stop the sound pressure at the rear drive end of the centrifuge at 2dB.

The declared values are based on measurements of the standard new machine.

Note that the sound pressure level is based on open ground conditions and is not a guarantee value. Due to the reflection of the wall and the surrounding environment on the sound, the sound pressure level of indoor installation is usually higher than that of open places.

In order to minimize the sound pressure level of the centrifuge, it is recommended that the centrifuge be installed in the room with low reflection on the surrounding wall and properly maintained.
