an oil reclamation device includes a full flow filter fitted around a partial flow filter within an open - ended casing . the open end of the casing is capped by a housing defining a vaporization chamber . in normal operation , oil flows from oil passage through the full flow filter to a branched leg . a metering jet provided in the branched leg allows a minor portion of the oil to flow through the partial flow filter and then into the vaporization chamber . the full flow filter extracts solid contaminants having a particle size of 15 microns or greater . the partial flow filter extracts solid contaminants of 1 micron or greater . the filter element of the partial flow filter is composed of compressed cotton fibers and preferably has a higher density in an upper end adjacent the vaporization chamber . in the vaporization chamber , liquid contaminants are removed from the minor portion by a heating element . the temperature within the chamber is monitored and controlled by a thermocouple and an indicating device is also provided to warn an operator when the temperature is not within an acceptable range . the oil passage includes a bypass valve so that oil can bypass the full flow filter when it is clogged . an audible or visual indicating means is provided to warn an operator when the bypass valve is opened .
