Vibration Reduction Products

VAD

‌Variable-type Absorption Damper
Product Application
  • Ensures dynamic stability of equipment when installed with a pneumatic mount system
  • Reduces tack time for production inspection equipment that generates dynamic loads
  • Equipment and sites requiring ultra-precision micro-vibration control, such as in semiconductor and display industries
  • Equipment requiring displacement control due to dynamic loads during operation
Product Features
  • Suppresses displacement caused by shock vibrations when combined with a pneumatic mount
  • Enables control of maximum displacement of the pneumatic mount with a locking feature
  • Minimizes fluctuation in the natural frequency of the pneumatic mount due to damping force
  • Easy installation and maintenance with adjustable damping force
  • Ensures damping performance even at small displacements, addressing the drawbacks of conventional dampers
