A discharge apparatus (1 or 41) for media to be atomized in ultrafine form has a discharge nozzle (3) with a sponge-like medium receiver (10), into which issue on the one hand a functionally closed source unit (50) for the medium and on the other a conveying or delivery device (11) for compressed air, so that by a control mechanism (40) initially a drop of medium spreads out in capillary manner in the receiver (10), after which by random actuation an air pressure surge flows through the receiver (10) towards the medium outlet (4). The medium is discharged from the medium receiver (10) in an already finely divided state, whirled up and once again is finely atomized in the vicinity of an impact atomizer (30) until it passes into the open with a minimum droplet size of max. 2 .mu.m.
