A separator is provided for separating liquids from a gas stream and has a plurality of separating profiles juxtaposed parallel to one another, each profile forming two curved deflection surfaces which lie opposite one another with the concave side laterally offset, wherein the deflection surfaces between them include a swirl chamber having an inlet gap and an outlet gap and terminate at their longitudinal edges in a projection that projects from the deflection surfaces and extends along the longitudinal edges. At least one of the projections has a first, substantially planar outer surface emanating from the deflection surface substantially transversely thereof and a second, substantially planar outer surface adjoining the first outer surface at an acute angle, so that the at least one projection forms a sharp edge that projects into the gas stream flowing along the deflection surfaces.
