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

All vibrators can be operated oil-free. A mist lubricator extends the service life of
the NCB and NCR.
Ambient
temperature
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.
Operating pressure
2,0 to 6,0 bar
Max. frequency NCT
The maximum permissible frequency must not be exceeded.

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.
