OIL CONTENT REMOVING DEVICE

PROBLEM TO BE SOLVED: To provide an oil content removing device capable of sufficiently removing an oil content contained in compressed air.SOLUTION: There is provided the oil content removing device having an inner container 4 which is configured so as to be housed in a filter case 2 while the inner container 4 houses a filter element 3 and in which an "oil content passage part" formed of a continuous foaming porous body is provided at a portion facing a discharge region of compressed air in at least an outside portion 3o of the filter element 3. The "oil content passage part" is configured to enable an oil content from a first space S1 to a second space S2 to pass through the "oil content passage part" caused by a pressure difference generated between the first space S1 and the second space S2 by introducing compressed air from a compressed air introduction part 11 into the filter element 3. An oil content discharge part 13 is formed so as to be capable of discharging the oil content, which is caused to pass through the "oil content passage part" and is discharged to the second space S2, to the outside of the filter case 2.
