At last count, there is somewhere between 10 and 15 companies offering centrifugal units in various parts of the world. This number may vary slightly as the companies come and go. Most of these units are based on the fundamental aspects of older Knelson technology while some go as far as to attempt to copy each piece as closely as possible without overstepping the bounds of Knelson Concentrator patents. Performance ranges from almost unusable to marginal. Nothing matches the performance of a genuine Knelson Concentrator.
