A water-spray separator for purifying particle-polluted discharged air (9) from a working area, especially for purifying discharged air containing paint particles from a spray-painting booth, with a flow duct adjacent to the working area and with a cross-sectional extent set by two spaced duct walls (1, 2) into which the polluted discharged air (9) flows and into which a fluid (8) is introduced to run along the channel walls (1, 2). The duct comprises and inlet (1a, 2a), and adjacent expansion section (1c, 2c), an adjacent deflection section (4) which deflects the flow of discharged air transversely to the direction of flow in the inlet (1a, 2a), an adjacent nozzle (5), an adjacent duct outlet (6) in which there is an abrupt narrowing (7) in the duct cross-section, and a reflector section (3) formed on the duct wall opposite the nozzle (5) against the direction of flow through said nozzle and reflecting the noise generated in the region of the nozzle (5) substantially back towards the nozzle (5).
