Air intake filter for combustion engines and other air-aspirating machinery operating under dusty conditions, the filter assembly having a cyclone separator stage and a dust collecting pan which is separated from the filter cartridge and cyclone chamber by a partition wall. The partition wall has a dust discharge opening with a fin-like guide baffle extending inwardly from the partition wall, the guide baffle having a circumferential wall portion and an arcuate radially inwardly pointing wall portion, thereby deflecting the dust particles away from the dust discharge opening.

An air intake filter assembly of the type which includes a generally pot-shaped filter housing with a longitudinal center axis, air inlet and outlet openings, a strainer-type filter element arranged centrally within the housing, and an annular space between the filter element and the housing wall and centrifuging means for causing the incoming raw air to be subjected to a dust-centrifuging helically swirling flow, prior to entering the filter element, said assembly, comprising: a dust collecting chamber which is arranged axially adjacent to said filter element and its surrounding annular space, on the axially downstream side of said helically swirling flow, said chamber being defined by a dust collecting pan which is connected to the filter housing and includes a substantially radially extending partition wall separating said annular space from the inside of the dust collecting pan; a dust discharge opening in the partition wall of the dust collecting pan, leading from said annular space into the dust collecting chamber; and a dust guide baffle arranged on the inside of the dust collecting pan, in association with its dust discharge opening, the dust guide baffle being so oriented that the dust particles passing through said opening, as a result of said helically swirling flow, are deflected radially towards the center of the dust collecting chamber.
