Abstract:
A one-piece, truncated conical annulus or dust separator body is molded from a high impact polystyrene material in such manner that a narrow rib is formed on the inner conical surface of the body to extend continuously in a spiral path from the larger to the smaller end thereof. A flange on its larger end is used to support the body in a vacuum cleaner chamber above a dust collecting canister. Dust-laden air enters the upper end of the body tangentially and cyclonically so that dust particles are urged outwardly by centrifugal forces, and are fed by the spiral rib downwardly into the canister.
