Abstract: An improved apparatus for filtration has a fluid mixture feed comprising light and heavy fractions fed into the workspace between counter-rotating disk impellers within a tank, thereby forming vortices in the workspace. A static radial exhaust array is located axially in the workspace, comprising exhaust channels, each of which has a peripheral end facing the workspace and an inner end communicating with an axial exhaust drain. An axial pump produces low pressure in the axial exhaust drain, thereby drawing in and anchoring the vortices to the peripheral ends of the exhaust channels so that the exhaust channels can extract the contents of the vortex cores. Vanes can be incorporated into the workspace surface of each disk impeller so that the opposed vanes pass in close proximity, forming vortices along a plurality of radial lanes of intersection, with the peripheral openings of each of the exhaust channels aligned with at least one of the lanes of intersection in the workspace.

Abstract: The replacement of filters for Heating, Ventilating, and Air Conditioning (HVAC) is often time-consuming and labor-intensive. Organizations having responsibility for many apartment or dormitory units can spend a significant fraction of their man-hours replacing such filters. A novel approach to reducing the labor for this task is to attach one end of sheet-type filtering material to a dispensing roll, and the other end to a gathering roll; both rolls being affixed to a frame. The assembly is installed into an air duct and the filtering material allowed to blouse, somewhat. The flow of air is intermittent in typical HVAC systems, so when the air begins to flow, the filtering material is forced, due to its resistance to flow, in the direction of the flow. This energy—a force applied through a distance—is utilized by a lever arm bracket to advance the gathering roll. In this fashion, new material leaves the dispensing roll and is exposed to the air, while the dirty filter sheet accumulates on the gathering roll.
