Dyncmech systems presents rubber air springs that provide highly effective insulation of machines against low frequency vibration/impact. This element has a vertical to horizontal natural frequency ratio 1:1. In addition, a safety stop is provided to prevent the element from squeezing suddenly in case of accident. Basically, this safety stop acts as a secondary vibration damper of a natural frequency of 10 hz. These are offered in four sizes from minimum load carrying capacity of 25 kg/piece to maximum 800 kg/piece and offers low natural frequency range [3-5 hz] at operating load.
