Abstract
Disclosed is an improved vortex attractor that utilizes a toroidal vortex within the attractor housing in order to establish a pressure differential between outside the device and inside. Furthermore, means to generate a cylindrical vortex to supplement the toroidal vortex are disclosed to increase attractor efficiency. The system of the present invention has the ability of achieving greater pressure drops than systems previously disclosed. Furthermore, it is easily fashioned into a flexible unit that can adapt to traversing curved surfaces.
