Abstract
A vortex separator for drawing a substantially moisture-free airstream from a waste stream having an annular channel defining a first vortex flow path for separating liquid and solid waste from this waste stream and preferably a filter unit with an inverted conical cavity between nested inverted cones defining a second vortex flow path that is isolated from the first vortex flow path for separating additional liquid and solid waste from the waste stream before it exits the vortex separator. In preferred embodiments, the separator includes a removable filter unit cartridge positioned within the outer cone and a helix isolator to respectively make use of the separator more convenient to use and more efficient.
