Features and benefits of Netter pneumatic vibrators and impactors :

  • Low air consumption
  • Frequency or impulse adjustable via air pressure
  • Amplitude of linear vibrators adjustable via the exhaust 
  • ATEX or stainless steel versions available

There are 3 different working principles:

  • Rotary vibrators generate rotary vibrations
  • Linear vibrators generate linear vibrations
  • Impactors generate impulses

The vibration characteristics of each vibrator are essentially defined by these 3 working principles. 

  • Rotary vibrators mainly generate high frequency vibrations with low amplitude
  • Linear vibrators generate lower frequency vibrations with higher amplitudes
  • Knockers generate impulses comparable to a hammer blow.

Each of the 3 working principles has its own specific vibration characteristics. The respective application dictates which principle can be most effectively implemented. Our application engineers will be pleased to advise.
