Abstract:
1. A cyclonic separator for separating particles and/or liquids from an airflow comprising: a separating chamber; an inlet for letting a flow of air entraining particles and/or liquids into said separating chamber; and an outlet for letting a flow of air, from which at least a portion of the entrained particles and/or liquids has been separated, out of the separating chamber, the outlet having at least one entry; means for causing the airflow to follow a cyclonic flow pattern through the separating chamber and around an axis for causing cyclonic separation of at least a portion of the particles and/or liquids from the airflow within the separating chamber; and at least one drum of which at least one interior surface portion extends circumferentially around said axis and bounds said separating chamber; wherein the at least one interior surface portion extending circumferentially around said axis is rotatable about said axis, wherein the inlet and the outlet enter and leave, respectively, the separating chamber coaxially with the axis of rotation of the drum bounding the separating chamber.
