In addition to the standard PAL series, Fabreeka regularly designs pneumatic isolators for OEM applications having custom requirements. Specially designed diaphragms may be used to lower the horizontal natural frequency of an isolator to approach 1.5 Hz. Alternatively, natural frequencies as low as 0.4 Hz can be achieved using pendulums.
For cleanroom applications, the exhaust air from the leveling valves is vented and the isolators are made using cleanroom compatible materials, cleaned and packaged. Isolators can also be made using non-magnetic materials and designed to fit in any space envelope.
For space simulation testing in vacuum, Fabreeka can provide vacuum-compatible, pneumatic isolators. These isolators operate in low vacuum (1 x 10-7 Torr) and are manufactured with low outgassing, vacuum-compatible materials. The leak rate on these isolators is less than 1 x 10-7 cc/sec.
