The AVI-Series :
Modular vibration isolation solutions


The isolation capabilities of the AVI-Series systems begins at 1.2Hz, increasing rapidly to 35db beyond 10Hz. The lack of any low frequency resonance means much better performance than with common passive air damping approaches. The inherent stiffness of the AVI-Series systems imparts excellent directional and positional stability. The outstanding performance of the AVI-Series includes all six translational and rotational vibration modes.

The AVI-Series compact units do not require any large tools for installation. We strive to offer an easy, user friendly handling concept - thus avoiding any complicated procedures when placing a heavy device (e.g. an SEM) on the units.

The modules of the AVI series are available as single units (AVI-200), double units (AVI-400), and triple units (AVI-600). The minimum configuration consists of two modules (units) and can be expanded. It is possible to use single-, double-, and triple units together in one system.

Main features

  • Active Isolation capabilities:
    1.2 - 200Hz in all 6 degrees of freedom (purely passive beyond 200Hz)
  • Piezoelectric sensor and actuator technology
  • Settling time: < 10ms
  • Performance (Reduction of incoming vibrations):
    5Hz > 22dB (92% reduction)
    10Hz > 34dB (98% reduction)
  • No Setup-time/calibration during day-to-day operation (only one-time initial weight-calibration required)
  • No air required
  • No low frequency resonance
  • Low power technology
    -> no heating up
    -> strongly reduced power consumption
    -> no electromagnetic disturbances

The AVI-Series active vibration isolation systems are available in several different sizes and load capabilities

Models

AVI-200 Series

The basic configuration of the AVI-200 vibration isolation system includes two single elements and one control unit and can isolate actively up to max. load of 400 kg. Higher loads can be easily accommodated by increasing the number of isolation elements. To adapt the AVI-200 to user specific applications, single elements in different lengths can be combined.

AVI-400 Series

The basic configuration of the AVI-400 vibration isolation system includes two single elements and one control unit and can isolate actively up to max. load of 800 kg. Higher loads can be easily accommodated by increasing the number of isolation elements. To adapt the AVI-400 to user specific applications, compact units in different lengths are available.

AVI-600 Series

The basic configuration of the AVI-600 vibration isolation system includes two single elements and one control unit and can isolate actively up to max. load of 1200 kg. Higher loads can be easily accommodated by increasing the number of isolation elements. To adapt the AVI-600 to user specific applications, compact units in different lengths are available.
