DATASHEET
Noise Declaration
Noise emission data for the decanter declared in accordance with the re-quirements in EN ISO 4871 and EN12547:
LwAd : Declared A-weighted sound power level from the decanter
LpAd : Declared A-weighted emission sound pressure level in a free field over a re-flecting plane at 1 m distance from the decanter
Uncertainty on declared values : LwAd : KwA=2 dB LpAd : KpA=4 dB
The noise does not contain significant impulsive or tonal components and the peak C-weighted instantaneous sound pressure level LpCpeak is below 130 dB(C) at all operat-ing speeds.
The emission sound power level is measured according to ISO 9614-2 while operating the decanter with water as process medium. The sound pressure level is determined from the measured sound power level according to EN ISO 11203.
The sound pressure level can vary –1dB to 2 dB at different positions around the decanter.
The declared values are based on measurements conducted on typical new decanters.
Note that the sound pressure levels are based on free-field conditions and not guaran-teed values. In a normal indoor installation the sound pressure level will be significant-ly higher than the declared free-field sound pressure level due to the reflection of sound from walls and surroundings.
In order to minimise the sound pressure level at the decanter it is recommended to in-stall the decanter in a room with low reflection of sound from the walls and always keep the decanter in a properly maintained condition.
