  • Cyclonic separator with secondary vortex break
    Patent number: 7377960
    Abstract: A cyclonic separator and methods of cyclonic separation which provide for a band pass separation of particles. That is, a cyclonic separator able to remove particles from an air stream that are greater than a predetermined minimum (which is greater than zero) while being smaller than a particular maximum. This band pass separation may be performed with the inclusion of a secondary vortex break on a cyclonic separator. Also discussed are cyclonic flow systems which provide for less deposition of aerosolized particles onto the cyclonic flow generator and related structures to improve likelihood of particles of interest being provided to an attached detector.
