Abstract: A suction assembly for a centrifugal air filter, including an axial fan for generating a cooling air flow and a Venturi nozzle having a flow pipe and an intake port which opens out in a constriction region within the flow pipe. The flow pipe in the outflow direction of the axial fan is penetrated by the cooling air flow in such a manner that a vacuum is initiated in the intake port.

Abstract: An air filter system for a utility vehicle includes a filter housing, a coarse filter located on an inlet side and accommodated in the filter housing, a fine filter arranged downstream in a filter operating direction of an airflow to be cleaned, and a cleaning arrangement accommodated in the filter housing for purging dirt particles separated at least in the fine filter counter to the filter operating direction.

Abstract: A centrifugal air filter for an automotive system includes a plurality of single separators for setting an air flow passing therethrough in a turbulent motion and a separation area surrounding the plurality of single separators. The separation area receives particles from the air flow due to the centrifugal forces. A filter housing portion is located below a predefined or operation position for receiving particles from the air flow due to gravity, and an intake pipe is connected by an extraction line to a connecting pipe emerging on a filter housing and opening into the filter housing portion.
