Abstract: A device (1) for separation of particles from a flow of gas is described. The device (1) comprises a first cyclone generator (6) comprising a first cyclone tube (8) with a length axis (4) and a first blocking means (9) arranged so that an annular first inlet (10) is arranged between the first cyclone tube (8) and the first blocking means (9). A first vortex generator (11) is arranged in the first inlet (10). The device comprises a further cyclone generator (12) comprising a further cyclone tube (13) with a length axis (4) and a further blocking means (14) arranged so that an annular further inlet (15) is arranged between the second cyclone tube (13) and the further blocking means (14), and a further vortex generator (16) arranged in the further inlet (15), and an outlet tube (22) comprising an outlet (23) and a length axis (4), which outlet tube (22) is arranged concentric in relation to the second cyclone tube (13).
