Abstract

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.
