Abstract
A cyclonic separator device for removing dust or debris from dirt-laden air includes a first separating chamber, a first dirt collection chamber in communication with the first separating chamber, a shroud, a second separating chamber positioned generally within the shroud, and a second dirt collection chamber in communication with the second separating chamber. The second separating chamber includes a generally frusto-conical portion that has an end part in communication with the second dirt collection chamber through which fine dust or debris exits therethrough into the second dirt collection chamber. A first portion of the second dirt collection chamber surrounds an outer surface of the end part of the generally frusto-conical portion to define a space S1 therebetween and said first portion of the second dirt collection chamber extends into a space S2 defined by the inner surface of the generally cylindrical portion of the shroud having said openings therein.
