Permitted operating conditions:
Drive medium:
Clean (filter ≤ 5 µm DIN ISO 8573-1 Quality Class 3)
compressed air or nitrogen
Operating pressure:
2 bar to 6 bar*
Pressure must not fall below or exceed operating pressures.
Lubrication:
A mist lubricator is recommended by NetterVibration for all vibrators.
Fill mist lubricators with acid-free and resin-free compressed air oil,
ISO viscosity class to DIN 51519, VG 5 to VG 15.
Recommendation: Klüber “AIRPRESS 15” for temperatures up to 60 °C.
The devices NTK 8 AL, NTK 15 x, NTK 18 AL, NTK 25 AL, NTK 28 AL, NTK
40 AL and NTK 55 AL can be operated oil-free after written guidance by the
application technicians of NetterVibration.
IMPORTANT
The use of a mist lubricator is compulsory:
for the devices NTK 16, NTK 25, NTK 40, NTK 55, NTK 85, NTK 110,
if additional swing masses are used,
when NTK vibrators are used as impactors,
if dried compressed air is used,
under extreme environmental conditions
NTK L versions are suitable for operation with oil-free, dried compressed air
complying with the compressed air quality, filter ≤ 5 µm, DIN ISO 8573-1 quality
class 3.
Ambient temperature:
NTK 15 x with plastic housing: 5 °C to 60 °C*
NTK with Al housing (black): 5 °C to 60 °C*
NTK with steel housing (orange): -10 °C to 60 °C* NTK NT
are low temperature versions: -32 °C to 60 °C NTK HT
are high temperature versions: 5 °C to 160 °C
The temperature must not fall below or exceed the allowed ambient
temperatures.
Ambient conditions:
When operated oil-free or in a dusty environment, NTK vibrators must not be used
without bellows or other dust protection.
Special versions (stainless steel, bronze) on request.
*) Operation at higher pressures and temperatures is only possible after guidance and written consent by the
application technicians at Netter GmbH.
Noise level:
Depending on type (with silencer) and 6
bar air pressure, the noise level is 64-79
dB(A), with lower air pressure below that.
Service life:
The technical performance data change
over long operating times (wear).
