Active vibration control systems, also called active vibration isolation or active vibration cancellation, are isolation systems that dynamically react to incoming vibrations. That is, they sense incoming vibrations and react to them, rather than passively reducing their effect by virtue of their mechanical structure. 

Since air-based isolation systems became widely commercially available forty years ago, they have become the standard for isolation of precision instrumentation. These systems provide a high degree of noise reduction at a moderate price. Air-based systems are offered in a wide range of sizes, form factors, and load capacities.

The technology behind the AEK Series was originally developed by Herz in Japan about twenty years ago. The AEK was made to provide an exceptionally quiet environment for sensitive research instruments. After studying Herz’s technology and production techniques, Ann Scanlan founded Herzan and brought the AEK concept to America. Herzan continues to develop and refine the AEK design.
