Abstract: An extractor hood (10) for the separation of dirt particles, and especially fat and oil droplets from airflow is described. Extractor hood (10) includes a fan unit (18) for the creation of exhaust airflow through the extractor hood and a separator unit (20) to deposit dirt particles from the exhaust air flow. The separator unit (20) defines at least one air duct (25a, 25b). Along the at least one air duct (25a, 25b) an impact element (40) is arranged, featuring at least in certain areas capillary holes (44) for separating dirt particles through the capillary holes (44) along the at least one air duct (25a, 25b).

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.
