ABSTRACT:
A centrifugal particle separator includes a first vane assembly and a second vane assembly. The first vane assembly includes a centrally positioned hub, a collar encircling the hub and a plurality of first vanes. Each first vane can have an inner end connected to the hub and an outer end connected to the collar, wherein a trailing edge of at least one of the plurality of first vanes can extend past an edge of the collar. The second vane assembly includes a centrally positioned hub, a collar encircling the hub and a plurality of second vanes circumferentially disposed about the hub. Each second vane can have an inner end connected to the hub and an outer end connected to the collar, wherein a leading edge of at least one of the plurality of second vanes can extend past an edge of the collar. When the first and second vane assemblies are secured together, at least one of the plurality of first vanes protrudes into the second vane assembly.
