Abstract: A centrifugal-force separator for separating particles from a fluid has a housing having an inflow opening and an outflow opening. An axial core and a plurality of guide blades connected to the axial core are provided, wherein the axial core and the guide blades are disposed in the housing. The guide blades generate a turbulent flow of a fluid flowing in through the inlet opening into the housing in an inflow direction. The guide blades extend radially between a first helical line at the axial core and a second helical line at a housing wall of the housing. A first pitch of the first helical line is greater than a second pitch of the second helical line.

Abstract: A centrifugal separator for separating particles from a fluid has a housing with an inflow opening and an outflow opening. Guide blades that generate a turbulent flow in a fluid flowing into the housing through the inlet opening are provided. The guide blades each have a leading edge. The leading edge of a first guide blade has a first spacing to a cross-sectional plane of the housing and the leading edge of a second guide blade has a second spacing relative to the cross-sectional plane of the housing, wherein the cross-sectional plane is perpendicular to an inflow direction of the fluid. The first spacing and the second spacing are different from each other. The first and second guide blades each have a length and the lengths differ from each other. Several centrifugal separators can be combined to a filter device.
