Abstract

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.
