Abstract

In a device for separating the particle size spectrum of a polydisperse aerosol comprising a housing including an inlet part, a guide part, an outlet part, a nozzle insert and a separation insert, all parts are axially symmetrical and joined by centering fits so that they are easy to manufacture and can easily be assembled and also replaced. The parts are so fitted together that they are automatically centered during assembly while providing for the properly sized aerosol and air supply and particle fraction extraction channels.
