A particle separator for removing both small and large particles from an airstream comprising: a cylindrical housing having an interior surface, an inlet end, and an outlet end; a rotor mounted rotatably about an axis within said housing, said rotor having a bladeless surface portion to minimize secondary flow swirl in said separator, said bladeless surface portion having an inlet end and an outlet end; an inducer portion for imparting rotational energy to said airstream as said airstream enters said housing at said inlet end of said housing, said inducer portion being adjacent to and rotating with said bladeless surface portion at the inlet end thereof; means for driving said rotor at high speed, a portion of said airstream between said bladeless surface portion of said rotor and said interior surface of said housing being caused to swirl around said axis at high speed by the rotation of said rotor, said large particles being forced radially outward closely adjacent to said interior surface of said housing at the inlet end of said housing, said small particles being forced radially outward closely adjacent to said interior surface of said housing near the outlet end of said housing; a first groove located in said interior surface of said housing at the inlet end of said housing for collecting said large particles; a first aperture in said housing communicating with said first groove, said first aperture allowing said large particles to be removed from said first groove to a location outside said housing; a second groove located in said interior surface of said housing at the outlet end of said housing for collecting said small particles; a second aperture in said housing communicating with said second groove, said second aperture allowing said small particles to be removed from said second groove to a location outside said housing; and an exducer portion for removing rotational energy from said airstream as said airstream leaves said housing at said outlet end, said exducer portion being adjacent to and rotating with said bladeless surface portion at the outlet end thereof.
