Abstract

L'invention concerne un dispositif de mesure de l'étanchéité à l'air d'une enveloppe de bâtiment (1), laquelle comporte au moins une ouverture de bâtiment (2) débouchant dans l'atmosphère. Ledit dispositif comprend au moins un ventilateur (4a, 4b, 4c, 4d) entouré par un boîtier (3). Le boîtier (3) comporte une face de prise d'air (5) et une face de sortie d'air (6) et peut être relié de manière étanche à l'enveloppe de bâtiment (1) tout autour de l'ouverture (2) du bâtiment par des panneaux de raccordement (7). L'invention vise à améliorer un dispositif de ce type, de telle manière qu'un résultat de mesure plus exact qu'avec l'état de la technique soit possible sans montage ni démontage du boîtier (3). A cet effet, l'invention propose un dispositif pour lequel le ou les ventilateurs (4a, 4b, 4c, 4d) sont montés de manière à pouvoir pivoter à l'intérieur du boîtier (3), un pivotement permettant d'alterner entre la face de prise d'air (5) et la face de sortie d'air (6).
