A water jet ventilator or aerator is provided for a sanitary fitting such as a faucet. The water jet ventilator has a jacket defining a water inlet and a water outlet, jet splitting obstacles and structure for mixing the jets with air. The ventilator device splits the flowing water into jets, mixes the jets with air and combines the flow into a stream. In the vicinity of the water outlet, the ventilator components in contact with the water are subject to calcification. According to the invention these components are provided with soft and/or water repellent surfaces to reduce or eliminate calcification and to facilitate cleaning. The soft surfaces facilitate cleaning because adhering lime is easily be detached by slight manual deformation of the surfaces to which the lime has adhered.
