Noise Statement
The noise of the centrifuge complies with the provisions of EN ISO 4871 and EN12547:
running speed
[rpm] Sound power level L wAd
[B (Are l pW] Sound pressure level L pAd
[dB(Are 20u Pa]
L wAd: A sound level sound energy level of centrifuge
L pAd: A sound level sound pressure level of the reflecting plane on the empty ground within 1m of the centrifuge
Change of declared value: L wAd: K wA=2 dB
L pAd : K Pa= 4 dB
The noise does not include pounding or tonal components, and reaches the peak at full speed
Sound pressure level at the moment of sound level
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.
