Abstract: A suction filter device for filtering oil includes a filter housing having an oil inlet opening and an oil outlet opening, via which a filter housing interior can be fluidically connected to a suction line. An oil filter medium is arranged in the filter housing interior between the oil inlet opening and the oil outlet opening, so that, by means of negative pressure generated via the suction line within the filter housing interior in relation to an environment of the filter housing, an oil flow can be generated from the oil inlet opening through the oil filter medium and through the oil outlet opening. Further, an oil-permeable and air-impermeable air separation medium is included. The air separation medium is arranged upstream of the oil outlet opening when a vacuum is generated via the suction line within the filter housing interior in relation to an environment of the filter housing.
