LOW FREQUENCY PNEUMATIC VIBRATION ISOLATION SYSTEM


Serva-Levl systems are pneumatic vibration isolation systems with three or more isolators and three height control valves to control the height of the isolators and the level of your equipment over long periods of time, even when there are moving weights or changes in loads.

High performance Serva-Levl systems offer the best performance available without active feedback. Serva-Levl systems will protect the floor from both machine generated vibration or it will protect the machine from vibration present in the floor.

Serva-Levl systems can have an unlimited number of isolators to support very heavy loads. The natural frequency of a Serva-Levl system is almost constant throughout its load range.

Features:

STANDARD

  • Vertical fn: 1.5-2.5 Hz
  • Horizontal fn: 3.5 Hz
  • Height control: ± 0.002"-0.015"
    (50-380
    µm )
  • Unlimited load copacity
  • Isolates 1 µ" to ± 0.012"
    (300
    µm) amplitudes
  • Low maintenance

OPTIONAL

  • Vertical fn as low as 0.5 Hz
  • Horizontal fn as low as 0.5 Hz
  • Height control: up to ± 0.0002"
    (5 µ±m)
    with VIP

Benefits:

  • Excellent passive isolation
  • Highly damped
  • Active height control
  • Isolates in 6 degrees of freedom
  • Automatic operation
  • Isolates wide range of amplitudes
  • Keeps equipment level relative to floor
  • Long life, trouble-free
  • No static deflection
  • Requires only shop air
  • Wide load range for any size
  • Easily adjustable, will not drift
