Zusammenfassung:	A downhole tool to separate liquid from a drilling fluid includes a multi-vein cyclonic separator disposed within a housing, the cyclonic separator including at least two veins extending in a spiral along the length of the cyclonic separator, holes in the housing positioned adjacent to edges of veins of the cyclonic separator to allow liquid accelerated from the drilling fluid to exit the housing, and wherein the cyclonic separator is configured to provide high centrifugal forces to the drilling fluid downhole.
