Abstract
Abstract Disclosed is an improved vacuum cleaning apparatus utilizing a self-sustained vortex flow in a centrifugal separator. More specifically, vortex flow is maintained via pressure differentials allowing the ejection of dust and other particles without bags, filters, or liquid baths. Furthermore, the impeller inside of the separator serves the dual purpose of moving fluid through the system as well as creating a cylindrical vortex fluid flow. Additional circulating blades present throughout the separation chamber prevent fluid flow from slowing due to frictional losses. The axial design of the present invention allows the centrifugal separator to be constructed with an arbitrary length. The present invention excels in producing clean fluid of a better quality more efficiently, more quietly, and more simply than devices known in the art.
