A secondary filter element for a filter system for filtering a gaseous fluid, in particular for a self-cleaning intake air filter system of a motor, has a filter medium which in the intended operation is flowed through by the fluid from an intended inflow side to an intended outflow side. The secondary filter element has a support element covering the filter medium at the intended inflow side. A filter system with such a secondary filter element is provided.

Secondary filter element and filter system

A separation device for separating fluid from a gas stream has a housing replaceably connected to a connector head of a connecting device. The housing has a housing corpus with an axial end covered by a housing cover non-detachably connected to the housing corpus. A filter insert is received in the housing in a flow path of the gas stream from a raw gas inlet to a clean gas outlet of the housing. The filter insert has a main separator element with ring-shaped support body and cylindrical coalescing filter medium with coalescer material removing fluid from the gas stream. A preliminary separator element is arranged concentrically to the main separator element in the housing in the flow path of the gas stream between raw gas inlet and main separator element. The preliminary separator element has a cylindrical coalescing filter medium with coalescer material removing fluid from the gas stream.

Separation device and oil separating air filter assembly comprising such separation device as well as method for separating fluid from a gas stream deriving from a connecting device

A separation device for separating fluid from a gas stream has a housing with housing corpus and housing cover non-detachably connected to the housing corpus. A hollow cylindrical filter insert is received in the housing in a flow path of the gas stream from a raw gas inlet to a clean gas outlet. The filter insert has first and second end discs at first and second axial end face sides. The filter insert has a main separator element with hollow cylindrical coalescing filter medium with coalescer material for removing fluid from the gas stream that is flowing radially through the main separator element. A preliminary separator element having a coalescing filter medium with coalescer material is arranged in the flow path of the gas stream between the raw gas inlet and the filter insert for removing fluid from the gas stream.
