Vibration Reduction Products

GAM

Gimbal-type Air Mount
Product Application
  • Equipment requiring high efficiency and low-frequency vibration isolation performance
  • Sites or equipment requiring nanometer-level, VC-D grade implementation
  • Equipment and sites requiring ultra-precision micro-vibration control, such as in semiconductor and display industries
  • Various inspection equipment, laser-related devices, 3D measuring instruments, and other precision measurement equipment
Product Features
  • Provides top-level vibration isolation performance in both vertical and horizontal directions in Korea
  • Reduces vibration effectively and shortens stabilization time through a dual-chamber system
  • Connects the air chamber and damping chamber with a variable orifice
  • Uses a high-precision leveler that ensures high repeat accuracy
  • Optional built-in oil damper available
Product Performance
  • Vibration Isolation Method: Air Spring
  • Natural Frequency: 1.5 ~ 2 Hz
  • Displacement Repeat Accuracy: ±0.05 mm ~ ±0.10 mm
  • Variable Damping Ratio: 5 ~ 15% (adjustable settling time available as an option)
  • Vibration Reduction Performance in 10 Hz Range: 90 ~ 99%
