A centrifugal oil filter includes a housing having a rotatable bowl disposed in a first fluid chamber and rotatably disposed about a shaft extending through the first fluid chamber. The rotatable bowl has a flow directing member connected generally at the bottom thereof to define a particle collection basin and the flow directing member extends upwardly to form a passageway adjacent the shaft so that the fluid flow within the rotatable bowl is directed to a pair of nozzles which act to rotate the rotatable bowl responsive to fluid flow therethrough. A particle retention insert is made of a cellular structure and disposed in the particle collection basin. The particle retention insert functions to receive foreign particles within the cellular structure and retain them therein by protecting the particles from the fluid flow within the rotatable bowl.
