Aerodyne  announces a cyclone dust collector that solves the problem of limited floor space or limited overhead clearance.  Unlike conventional cyclones, the GPC Dust Collector uses an innovative ground-plate design that increases efficiency in a more compact unit.  As a result, it costs less than comparable units and is just as efficient as dust collectors 1.5 to 2 times its size.

 The unique design of the GPC Dust Collector provides a high-efficiency, compact unit that is available in horizontal or vertical configurations.  The Aerodyne GPC Dust Collector is designed to reduce particulate emissions at processing plants, reclaim useful material from air/gas waste streams, or as a pre-filter in front of baghouse filters. It handles a wide variety of dry materials including sawdust, sand, plastics, cereal/grain, and many others.  A conventional cyclone dust collector consists of a tangential inlet and a long, tapered body. This design relies on gravitational force to direct the dirty gas stream downward. As the gas stream becomes constrained in the narrow end of the cyclone body, a phenomenon known as "vortex reversal" occurs, in which a secondary inner vortex is generated and moves upward through the center of the dust collector and is exhausted from the top. 

Vortex reversal is a major cause of inefficiencies in cyclone dust collectors because it takes with it any particulate that did not have the inertia to be forced against the collector walls. The long body of a conventional cyclone is intended to give fine particulate more time to reach the walls of the dust collector.  Aerodyne's GPC Dust Collector operates differently.  A spiral inlet directs the dirty gas stream toward a ground-plate above the hopper. The ground-plate forces vortex reversal to occur in a much shorter space, eliminating the need for a long, tapered body. As the gas stream strikes the ground plate, fine particulate that has not completely made it to the dust collector walls is deflected into the hopper.  The ground-plate shields collected particulate from the forces of the vortex reversal, acting as a barrier between the separation chamber and the collection hopper.
