Abstract: An individual component assembly for filtering fluid, comprising, in combination a centrifuge device operable to filter said fluid, stand structure mounting the centrifuge device, to be directly accessible, at least one fluid filter connected in operating flow passing series with the centrifuge, and openly and accessibly carried by the stand structure, pumping means associated with the stand structure for pumping fluid to flow through said fluid filter and then through the centrifuge.

Abstract: A centrifuge, comprising an upright shaft, defining an axis, a fluid centrifuging chamber rotatable about the shaft axis, first porting extending endwise in the shaft and opening laterally to said chamber, to deliver fluid to be centrifuged, to the chamber, a structure in the chamber and into which contaminate in the fluid is centrifuged for separation from the fluid, during chamber high speed rotation, a rotor supporting the chamber for rotation about the axis, the rotor rotating with the chamber, there being at least one fluid outlet to jet fluid discharged from the rotor, and passage structure for delivering fluid that has been jetted via the fluid outlet.

Abstract: A centrifuge, comprising in combination a motor driven shaft, a fluid centrifuging chamber carried by the shaft, to rotate therewith, first porting extending endwise in the shaft and opening to said chamber, to deliver fluid to be centrifuged to the chamber, a matrix in the chamber and into which contaminate in the fluid is centrifuged for compaction and separation from the fluid, during chamber high speed rotation, second porting extending endwise in the shaft and communicating with the chamber, to receive fluid from which contaminate has been separated, fluid delivering inlet structure communicating with said first porting, and fluid outlet structure communicating with the second porting. The shaft and centrifuging chamber are assembled via a flange on the shaft that closes the end of the centrifuging chamber.
