Fans / Air-Conditioners

Fans consist of a motor and the actual axial or centrifugal fan. Smaller units sit simply on a steel frame while larger units, especially the large axial fans, need a concrete foundation. Vibrations caused by fans depend on their balancing quality, which will deteriorate over the time by residues sticking to the rotor as well as due to wear and tear.

GERB systems, consisting of spring elements and Viscodampers®, are designed to take care of all of that and additionally offer protection against damages caused by earthquakes.
