Active anti-vibration unit VAAV-S linear motor type

VAAV-S Linear active anti-vibration unit.
This can operate with a small compressor.
Can get high a performance with low cost.
EMS countermeasure type.

Active anti-vibration unit VAAV-S linear motor type

This series cancel vibration with high speed airless actuators and high sensitive sensors using our original algorithm.

An air supply is only used for load supporting. So, if you have only small compressor and a power supply, you can get a world highest level performance concerning vibration isolation, using this equipment.

The best performance of anti-vibration can be realized with the same softest air cushions as VAAV-L Series

Merits

  • Vibration transmission characteristic without resonance.
    In the softest air springs in VAAV series, this type has the highest anti-vibration performance.
  • With linear motor control, this type consumes small amount air as small as passive control.
  • This type is optimized for an accurate measurement equipment which is sensitive to vibration and for low frequency big vibration.
  • Highest cost performance among VAAV series.
  • Vibration waveform display software is attached on standard system.

Product usage

  • An electron microscope needs anti-vibration board to prevent from its picture blurring.
    This series are active in the field of low frequency anti-vibration where no passive control system cannot be active.
  • These series are used by scanning tunneling microscopes, atomic force microscopes and optical measuring devices which are especially sensitive to fine vibration.
  • For the solution of low frequency vibration noise on the floor.
