Abstract:  
The present invention provides several novel features in the art of centrifuges. For one thing, the only motion within the device is that of the fluid itself passing through the purifier in two or more stages of rotary motion. An important feature of the invention is that fluid is normally forced into the top of the device with a tangential motion resulting in a primary centrifugal cleaning of the fluid, and then a second high-speed stage of centrifugal motion is provided speeding the fluid up to a maximum predetermined velocity, as it passes from an upper section of the purifier to a lower section. Another important feature of the device is that this maximum predetermined velocity, as it passes from an upper section of the purifier to a lower section.
