Technical Data; Sound Level - NetterVibration NCT Series Operating Instructions Manual

Operation of the vibrators with silencers is mandatory.
Silencers reduce the noise level and protect the vibrators from contamination entering.

Sound level

The sound level is largely determined by the mounting surface (e.g. sheet metal) on which the
vibrator is mounted. Depending on the type, the sound pressure level with a silencer is 75-
85 dB(A) at 6 bar air pressure, at lower air pressure it is below this. Sheet metal which is not
silenced increases the sound level.
NOTICE
NCT must be operated with clean compressed air or nitrogen according to the
following specification, according ISO 8573-1:
[ 5 :
Filter ≤ 5 µm
NCB and NCR must be operated with clean compressed air or nitrogen accord-
ing to the following specification, according ISO 8573-1:
[ 5 :
Filter ≤ 5 µm
All vibrators can be operated oil-free. A mist lubricator extends the service life of
the NCB and NCR.
Standard: -20 °C to 120 °C
HT-versions: 80 °C to 200 °C (with brass grommet and sintered silencer)
Important: Below the specified ambient temperature (< 80 °C) the performance
of the HT-version is reduced.
2,0 to 6,0 bar
The maximum permissible frequency must not be exceeded.
