ABSTRACT:
An apparatus extracts standardized samples of wear particles from a series of used oil filters by rotating each oil filter while spraying a solvent fluid into the opening at the base of the oil filter. The apparatus includes a housing to hold the filter having a movable cover and a base that contacts the filter base and allows rotation of said filter. A crawler assembly within the housing cover initially translates along the axis of rotation toward the housing base until the filter is held between the crawler and the housing base. A motor associated with the crawler assembly (or the housing base) then rotates the filter. A shaft extending through the housing base into the filter opening carries a nozzle that directs a spray of fluid into the filter during rotation to rinse wear particles from the filter for subsequent analysis. A predetermined quantity of fluid is sprayed into each filter to produce a standardized sample. The interior of the housing also sprayed with fluid between consecutive filters to prevent cross-contamination.
