Les Informations Saisies sur la Table suivante constituent un Guide général de Compatibilité chimique des Filtres AIRPEL avec divers Fluides. La Temperature, la Pression, La Concentration, ou ia nature des contaminants induit une extrême vigilance quand au choix des différents Filtres AIRPEL. DUBUISSON FILTRATION Vous aidera, en fonction de la précision des éléments fournis, à selectionner les meilleures matériaux pour une durabilité accrue de votre filtre Airpel. Cependant il incombe à l'utilisateur finale de s'assurer de la compatibilité effective de nos préconisations dans le cadre de l' application et/ou du Process. De la même manière cela implique les précautions prisent pour la protection des Opérateurs, les autres équipements ainsi que l'environnement. Lorsqu'aucun type d'élastomère n'est mentionné, il apparait que l'étanchéité préconisé est le nitrile dans tous les cas excepté pour l'acier inox où le Viton est monté de série. Dans le cas ou une étancheité spécifique serait requise, merci de le préciser.
