Abstract: The invention is separator for separating a fluid flow of gas with droplets (G, L), comprising an inlet (10) for the gas to be separated to a rotor (4) with a mesh (5) for coalescing the droplets (L) and releasing coalesced liquid (L?) from a peripheral part (50) of the rotor (4). Novel features of the separator is that—the mesh (5) generally forms an axial passage for said gas (G) from the inlet (10), through said rotor (4), to an outlet (20) for liquid depleted gas (G?), and—the rotor (4) with the mesh (5) is arranged for transporting the coalesced liquid (L?) laterally out of the axial passage to a wall (6) arranged for receiving the coalesced liquid (L?).
