Apparatus for separating dirt and dust entrained in an airflow therefrom, comprising a bin (12) having an outer wall (14) with a circular cross section, a tangential airflow inlet (16) for introducing the airflow to the bin (12) substantially tangentially to the outer wall (14), and an airflow outlet, wherein settling means (22), for encouraging dirt and dust collected in the bin (12) to settle, are provided inside the bin (12). Preferably, the settling means comprise inwardly extending projections, advantageously in the form of fins or baffles (22). This arrangement encourages dirt and dust separated from the airflow to remain in the bin (12) and discourages re-entrainment with the airflow. |
