Application

PAL Series for protecting sensitive equipment:

Precision Aire™ levelling PAL air spring systems from Fabreeka® use automatic levelling air springs. These isolators are ideally suited for conditions requiring both height control and vibration isolation. Fabreeka® PAL isolators meet all of the essential requirements for instrumentation, electron microscopes, measuring stations and precision manufacturing machines.


RLA Series to isolate large amplitude emitting equipment:

For effective vibration and shock isolation in all kinds of dynamic testing equipment such as:

  • Automotive test benches (such as road simulation, MAST, Hexapod, hydropulse units).
  • Earthquake simulation equipment.
  • Wind power test benches.
  • Railway test benches.
  • Aircraft component testing systems.
  • Material testing stations.
  • Emergency generators, with or without foundations.
  • Shredders.
  • All other kinds of large foundation.

Description

PAL Series for protecting sensitive equipment:

Precision Aire™ air spring elements with automatic levelling (PAL).


Air spring elements in the PAL series provide superior low-frequency vibration isolation for measurement equipment, electron microscopes, MRI scanners, coordinate measuring machines and precision manufacturing equipment. Precision Aire™ levelling PAL air spring systems from Fabreeka® use automatic levelling air springs. These isolators are ideally suited for conditions requiring both height control and vibration isolation. Fabreeka® PAL isolators meet all of the essential requirements for instrumentation, electron microscopes, measuring stations and precision manufacturing machines.


Features and benefits:

  • Standard Fabreeka® PAL isolators have natural frequencies from 1.5 to 2.7 Hz, depending on isolator height.
  • Bespoke isolators optionally have even lower natural frequencies (down to 0.5 Hz).
  • PAL air springs respond quickly to changes in load and centre of gravity. 
  • Deviations from positions once present are automatically readjusted.
  • A complete Fabreeka® PAL system consists of at least three main master isolators for three-point level control.
  • Each isolator has an integrated level-control valve that functions as a load sensor and height control.
  • Any number of additional slave isolators may be added to support the total device weight.


RLA Series to isolate large amplitude emitting equipment:

Fabreeka Precision Aire belted bellows RLA type rang.


RLA air springs are calculated and prepared following pressure vessel regulations DGRL 2014/68/EU. Production and assembly processes in regards to safety, testing and quality control are in accordance with Machinery Directive 2006/42/EC. RLA air springs are equipped with safety valves for overpressure and over travel limitation functions as standard.


Features and benefits:

  • Load range of 3,500 kg to 31,500 kg depending on design size.
  • Virtually constant load-independent vertical natural frequency over a wide load range.
  • Low vertical natural frequency to below 0.7 Hz (optionally with additional volume).
  • Switchable vertical natural frequency (optionally with additional volume).
  • Progressive vertical stiffness curve n Horizontal natural frequency adaptable by design in a wide range to match a particular application.
  • Low-noise version (sound hardness at E2 4.45 kg/m²/s) for best possible solid-bound soundproofing.
  • niveautone® design using mechanical-pneumatic Triflow® proportional control valves.
  • Optional pneumatic double chamber principle for effective visco-pneumatic system damping.
  • Effective damping behaviour by optional adjustable laminar flow damping.
  • Optional internal viscous safety damping for Lehr’s damping ratios up to 0.25.
