Airborne Noise Emission

The A-weighted sound pressure emitted by
this product is below 70 dB.
** The noise level can vary depending on the
site.
The figures quoted are emission level and are
not necessarily safe working levels. Whilst
there is a correlation between the emission
and exposure levels, this cannot be used reli-
ably to determine whether or not further pre-
cautions are required. Factor that influence
the actual level of exposure of the workforce
include the characteristics of the work room
and the other sources of noise, i.e. the num-
ber of equipment and other adjacent process-
es and the length of time for which an opera-
tor exposed to the noise. Also, the permissi-
ble exposure level can vary from country to
country. This information, however, will
enable the user of the equipment to make a
better evaluation of the hazard and risk.
