US Patent 7731770 Separating apparatus

A separating apparatus includes a shroud that has a wall having a multiplicity of through-holes. At least one baffle is provided on the inner surface of the wall of the shroud. The baffle directs the airflow entering the shroud towards the central region of the shroud, thereby reducing conflicting air currents. The baffle may also be used to assist correct assembly of the separating apparatus. The baffle may be arranged to locate with a member provided on another component of the separating apparatus, such as a cyclone assembly, in order to locate that assembly in a predetermined orientation.
