The  basic configuration of the AVI 400-S includes two compact units and one control unit and isolate actively up to a max. load of 800 kg. Support of higher loads can be easily achieved by increasing the number of compact units. To adapt the AVI 400-S to user specific applications, compact units in different lengths are available.

 

The isolation of AVI 400-S begins at 1 Hz, increasing rapidly to 35 dB beyond 10 Hz

The lack of any low frequency resonance means much better performance than with common passive air damping approaches

The inherent stiffness of the AVI 400-S systems imparts excellent directional and positional stability

The outstanding performance of the AVI 400-S includes all six translational and rotational vibration modes

 

The AVI 400-S 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.
