Abstract: A collecting hood for capturing exhaust air above cooking areas, production devices and the like is provided. The collecting hood includes a vapor chamber, an extraction chamber and an air supply chamber. The vapor chamber is downwardly open and tapers upward. The extraction chamber is separated from the vapor chamber by a filter or a separator. The filter or separator forms an inclined boundary of the upwardly tapering vapor chamber. The air supply chamber tapers downward and merges at its bottom end into a curved deflection region which opens out into a discharge opening which is arranged at a bottom end of the vapor chamber. Supply air, which is blown into the air supply chamber, emerges from the discharge opening horizontally or upwardly at an angle in the direction of the filter or separator. A negative pressure chamber is arranged between the vapor chamber and the air supply chamber.

Abstract: 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.

Abstract: The invention relates to a plate-shaped separator for separating fluids from a gas flow, particularly for separating oil mist, wherein the flow hits the separator transversely, wherein the separator comprises a plurality of separating profiles, which are arranged in parallel next to each other transversely to the flow direction of the gas flow and which each form two curved deflection surfaces, which lie opposite each other in a laterally offset manner with the concave side thereof and on which a gas flow to be purified flows along successively, wherein the deflection surfaces enclose an eddy chamber having an inlet gap and an outlet gap between said deflection surfaces and end at the longitudinal edges of the deflection surfaces in a protuberance that projects over the deflection surfaces and extends along the longitudinal edges, wherein in order to further improve the separation of particles from the gas flow to be purified, it is proposed that at least one of the protuberances comprise a first substantiall
