Abstract

The invention is an entrainment device for a centrifugal separator. The entrainment device is comprised of two axial delimiting surfaces. One axial delimiting surface turns axially towards and the other turns axially away form an inlet chamber outlet of the separator. The entrainment device permits extended periods of operation without clogging of inlet chamber.
