FIELD: hydraulic equipment.
SUBSTANCE: device (1) for producing stream of air (F'), comprising enclosure (10), which is intended for containing volume of liquid (V), and which comprises at least one air-discharge opening (101), air-injection means (12) which make it possible to create and pass incoming stream of air (F) from the outside of the enclosure into volume of liquid (V) contained in the enclosure, by injecting said incoming stream of air (F) into said volume of liquid (V) underneath the surface of said volume of liquid (V), such that outgoing stream of air (F'), treated by direct contact with volume of liquid (V), is discharged from said enclosure by passing through air-discharge opening (101) of the enclosure. Enclosure comprises one or more baffles (14; 14'; 14''), which are positioned between volume of liquid (V) and said discharge opening (101) and which make it possible to circulate the stream of air (F'), exiting volume of liquid (V) until discharge opening (101), causing same to undergo one or more changes of direction such as to prevent the spraying of liquid through air-discharge opening (101).
EFFECT: device for generating a stream of air through a volume of liquid is provided.
