Decoupling of ambient vibrations .

Measurements made on a glass measuring table led to unusable results because the isolator used was unable to cope with the lateral stiffness of the products used. Only low-frequency pneumatic isolators with automatic level control of the type PAL 21-6 ACE could provide a remedy. A special feature of these membrane pneumatic isolators lies in the level control valve, which has, by virtue of its construction, an above-average longevity. Relatively large acceleration forces can lead to horizontal movements and it is particularly in such situations that the robustness and durability of the isolation system make a significant contribution.

High-end in different sizes.

For superior low frequency vibration isolation: PAL high-quality air springs are designed for conditions in which the user wants to ensure that equipment is constantly level and isolated from vibrations at the same time. 

The PAL system is an air spring system with level control that reacts quickly to loads and center-of-gravity changes. They automatically adjust deviations from the pre-set position. The system is available in three different sizes for loads from 79 lbs to 100,000 lbs (36 kg to 42,000 kg) per air spring with a natural frequency up to 1.7 Hz. Customized isolators with a natural frequency of up to 0.5 Hz can be manufactured upon request.

PAL isolators meet the critical needs of metrology instruments, electron microscopes, inspections stations and precision manufacturing equipment.
