PAL - Low Frequency Pneumatic Precision-Aire Leveling Isolators
PAL-type pneumatic isolators provide superior low frequency vibration isolation. These isolators are ideally suited for conditions where height control and low frequency vibration control must co-exist. Fabreeka PAL isolators meet the critical needs of metrology instruments, electron microscopes, inspection stations and precision manufacturing equipment.
- The standard Fabreeka PAL isolators have a natural frequency as low as 1.7 Hz, however, lower natural frequencies (0.5 Hz) can be obtained from custom designed isolators.
- PAL isolators react quickly to changes in the supported load and to center of gravity shifts by automatically releveling to a preset position.
Can support payloads from 100 to 120,000 lbs per isolator.
- Settling time is minimal with optimum damping and corresponding valve flow.
