A continuous, self-cleaning rotary filtering system is herein provided which includes a plurality of filtering elements within a rotatable filter housing adapted for rotation between an inlet plate having single or multiple inlet ports and an outlet plate having single or multiple outlet ports so that a substance to be filtered is passed from the inlet ports through at least one incomplete toroidal cavity within the inlet and outlet plates, through the filter elements and into the outlet ports. The apparatus is further provided with single or multiple backflushing capabilities, whereby, when the filter housing is rotated passed a single or multiple backflush port, a cleaning agent will be caused to flow backward through at least one of the filter elements and backflush ports to purge contaminants from the system via the backflush port or ports without interrupting the stream flow or pressure of the substance to be filtered. Also, several different substances may be used at the same time through multiple backflush ports, such as the filtered substance itself, solvents, air, steam, oil, etc. and the output of one of the output ports may be fed back into the input of a second input port for additional cleaning through a series of different filters which may have different characteristics.
