Abstract

Le plan de travail à protéger (1) est dégagé et accessible à la fois sur le dessus (102) et sur au moins un côté, appelé côté libre (100). Le procédé est remarquable par le fait qu'on insuffle en continu de l'air propre au-dessus du plan de travail (1) à partir du côté (101) opposé au côté libre (100), sous la forme d'un flux sensiblement horizontal qui balaie le plan de travail (1) transversalement, en direction du côté libre (100), et qui présente un gradient de vitesses tel que la couche supérieure - ou veine haute - (V1) ait une vitesse sensiblement plus grande que celle de l'air circulant au voisinage de la face supérieure (10) du plan de travail (1); on aspire en continu la totalité ou la majeure partie du flux par le côté libre (100), au moyen d'une bouche d'aspiration (20) s'étendant le long et à proximité immédiate du bord (10b) du plan de travail (1). Protection d'un plan fixe ou mobile supportant des articles variés sensibles à la contamination de l'atmosphère ambiante.
