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.
