An oil reclamation device includes a housing that has an interior divided into at least two areas by a somewhat upright, generally conical vaporization plate. The area which is above the plate is a vaporization chamber at or less than atmospheric pressure. The area which is below the plate is pressurized filter area, usually the pressure is supplied by the oil pump of an engine. The bottom of the vaporization plate has a plurality of dependent heat transfer fins for creating a turbulent and uniform heat transfer from the vaporization plate to the oil. The top of the plate contains a cup terminating holes for transferring oil from the area below the plate into the cup. A covering washer forces oil in the cup to form a thin film. The transferred oil overflows the cup and runs, under gravity, down an oil-confining, helical channel which conically spirals downwardly. The entire area above the plate is heated to a vaporization temperature at a low pressure, so that there are no cold spots in the heated area for recondensing contaminants after they have once been vaporized. The oil filter may continuously filter the oil in, say, an engine using motor oil or upon demand at a machine using industrial or cooking oil. Or, it could be used to clean batch-loaded oils.
