Abstract

A miniature centrifugal separator for use in an engine air cleaner. Two cn air take-off tubes are coaxially aligned in the main flow tube for successively removing selected fractions of the outer annular portion of the swirling gas stream. The clean air tubes are spaced pre-selected distances downstream from the swirl means such that entrained dust particles are enabled to complete approximately one swirl revolution prior to encountering each take-off tube. The invention seeks to accomplish a relatively high collection efficiency with a relatively short flow tube.
