Vibrations and oscillations have a negative impact on both the man and machines being the source of these harmful factors.

Vibration isolation is a process of minimization of an oscillation amplitude of a set devices by introducing additional damping elements to its construction – vibration isolators.

Examples of a vibration isolating setting:

extractor fan
Eccentric press

APPLICATION of vibration isolators ensures:

  • suppression of vibrations, oscillations and noise
  • fast, easy mounting and precise leveling
  • easy movement of devices to alternative location

Effective functioning of vibration isolators depends on the choice of parameters, depending on the parameters of a mounted device.

Basic parameters include:


Vibration isolator:

  • load range
  • natural frequency
  • fixing method to a mounted device

Mounting devices:

  • device’s full mass
  • amount of points of support
  • load concentration on a point of support
  • rotational speed of spinning/rotating elements


The most important parameter affecting the effectiveness of vibration isolation is the ratio of the frequency of the force causing a device to oscillate fwym to the natural frequency of a vibration isolator’s oscillation fwib results.

The frequency of the force causing a device to oscillate fwym results from e.g. the rotational speed of the spinning/rotating elements (ventilator’s rotor, motor, main driveshaft).

The below graph presents how the fwym/fwib ratio affects the effectiveness of vibration isolation.

Two areas have been highlighted on THE GRAPH:

1. Area of resonance:

A device is in this area if the ratio fwym/fwib is close to unity. The amplitude of deterministic vibration increases repeatedly which can cause a device’s irreversible damage.

2. Area of effective dampening:

for a device to remain in this area, a vibration isolator has to be selected, so that the fwym/fwibratio is higher than 1,42. The highest effectiveness of vibration isolation (over 90%) is achieved if the ratio is higher than 3,5.

The green curve presents the dependency between the percentile effectiveness of vibration isolation and the fwym/fwib ratio.

Benefits deriving from the application of our vibration isolators:


  • decrease of dynamic forces transferred from a device to the floor/foundation
  • isolation of a device from the oscillations transferred by the floor
  • suppression of vibration, isolation and noise in adjacent premises
  • ease of assembly and precise leveling of machines and devices
  • low cost of devices’ mounting – elimination of deep foundations
  • enhanced precision of processed surfaces
  • shortened time of investment due to rapid activation of devices mounted on vibration isolators
  • easy and rapid change of machines’ and devices’s location in case of work profile’s
