1. Apparatus for separating particulate matter from a fluid stream, the apparatus comprising:
- a housing including intake means for intake of particulates-containing fluid;
a separation zone in the housing that includes primary and secondary separation chambers each associated with respective particulates collection means;
primary vortex generating means in the housing configured to generate a primary vortex in the intake fluid;
interconnection means formed in the housing and adapted to generate a secondary vortex in the secondary-separation chamber, the interconnection means forming a demarcation region, whereby particulates entrained in the intake fluid are urged through the interconnection means under the influence of centripetal force with no net flow of fluid through the secondary separation chamber; and
exhaust means for exhaust of cleaned fluid.

19. A method for separating particulate matter from a fluid stream, the method comprising the steps of:
-
passing particulates-containing fluid in a vortical pathway to a primary separation chamber; and
permitting the vortical fluid stream to be divided between said primary chamber and a secondary separation chamber interconnected thereto and configured to generate a secondary vortical pathway in the secondary chamber, whereby heavier particulates are passed to the secondary chamber and separated from the secondary vortical fluid stream while lighter particulates are retained in the primary chamber and separated from the primary vortical fluid stream, and wherein the interconnection of the chambers is formed with a demarcation region operative to minimize turbulence between the vortical fluid streams, whereby particulates entrained in the intake fluid are urged through the interconnection means under the influence of centripetal force with no net flow of fluid through the secondary separation chamber.
