Document Type and Number:

WIPO Patent Application WO/2019/010675

Kind Code:

A1

Abstract:

A separation device (100,100') for separating fluid from a gas stream deriving from a connecting device of a compressed air system or of a vacuum pump, the separation device (100,100') comprising a housing (16, 18) being designed to be replaceable connected with a connector head (200) of the connecting device, wherein a hollow cylindrical filter insert (20) is received in the housing (16, 18) in the flow pass of the gas stream between at least one raw gas inlet (30) and at least one clean gas outlet (32),wherein the housing (16, 18) comprises a cup-shaped housing corpus (18) and a housing cover (16) for covering a first axial end of the housing corpus (18), wherein the housing cover (16) is non-detachably connected to the housing corpus (18),wherein the filter insert (20) comprises at least one main separator element comprising at least one hollow cylindrical coalescing filter medium (23) comprising at least one coalescer material for removing fluid from the gas stream, and wherein in the flow pass of the gas stream between the raw gas inlet (30) and the filter insert (20) is arranged at least one preliminary separator element (40), in such way, that a preliminary separation of the gas stream having streamed into the housing (16, 18) by the raw gas inlet (30) is provided with low costs and low volume, it is proposed that the preliminary separator element (40) comprises at least one coalescing filter medium, comprising at least one coalescer material for removing fluid from the gas stream, the separation device (100,100') is designed in a compact manner and is inexpensive and easy to manufacture.
