ABSTRACT:
A device for removing suspended particles from an airflow has an intake opening, an air conveying the duct, and a fan. The air conveying duct deflects the airflow with regard to its flow direction at least sectionally. In order to filter the suspended particles almost completely from the air, the airflow is guided in the air conveying duct by positive guiding elements along a general conveying direction such that the airflow is subjected to at least a twofold sequentially arranged curve-shaped deflection in different directions. The height of at least one positive guiding element projecting into the air conveying duct is smaller than the free height of the flow cross-section of the air conveying duct in the area of the positive guiding element.
