The invention relates to an air outlet (1, 1'), comprising a connecting piece (2) for the at least indirect connection to an air supply system, a housing (4) delimiting an air distribution chamber (7), and a perforated plate (5) forming an effective air discharge cross-section (10) of the air outlet (1, 1'), wherein a center line (9) of the connecting piece (2) is oriented perpendicular to the perforated plate (5). Starting from a center region of the housing (4), in which the connecting piece (2) empties into the air distribution chamber (7), walls (11) of the housing (4) that face the perforated plate (5) wrap around and extend in the direction of the perforated plate (5), inclined at an acute angle .alpha. in relation to the perforated plate (5). The invention further relates to a suspended ceiling or a wall paneling, and to a method for producing a previously described air outlet (1, 1'). In order to refine the air outlet known from the state of the art regarding the flow behavior of the escaping air, and in order to improve the optical properties and provide a simplified method for producing an air outlet, according to the invention the perforated plate (5) is a panel (6) of a louvered ceiling or a wall paneling.

L'invention concerne une sortie d'air (1, 1') comprenant: une tubulure de raccordement (2) pour la liaison au moins indirecte avec un système d'alimentation en air ; un boîtier (4) qui délimite une chambre de distribution d'air (7) ; et une tôle perforée (5) qui forme une section efficace (10) de sortie d'air de la sortie d'air (1, 1'). Un axe médian (9) de la tubulure de raccordement (2) est orienté perpendiculairement à la tôle perforée (5). En partant d'une région centrale du boîtier (4) dans laquelle la tubulure de raccordement (2) débouche dans la chambre de distribution d'air (7), des parois (11) du boîtier (4), tournées vers la tôle perforée (5), s'étendent tout autour en direction de la tôle perforée (5) en étant inclinées sous un angle aigu .alpha. par rapport à la tôle perforée (5). L'invention concerne en outre un plafond suspendu ou un revêtement mural et un procédé de fabrication de la sortie d'air (1, 1') décrite ci-dessus. L'invention vise à perfectionner la sortie d'air connue dans l'état de la technique en ce qui concerne le comportement d'écoulement de l'air sortant, ainsi qu'à améliorer son aspect extérieur et à fournir un procédé simplifié de fabrication d'une sortie d'air. A cet effet, la tôle perforée (5) est un panneau (6) d'un plafond grille ou d'un revêtement mural.
