FAQ

Les produits Gast sont utilisés dans un large éventail de secteurs, notamment l'agroalimentaire, la fabrication industrielle, la santé et le bien-être, les laboratoires, l'emballage, l'imprimerie et la manutention. Nos technologies sont mises en œuvre partout où un flux d'air fiable, la génération de pression ou des performances de vide sont nécessaires.

Un compresseur d'air augmente la pression de l'air au-delà de la pression atmosphérique afin de fournir de l'air comprimé, tandis qu'une pompe à vide évacue l'air pour créer une pression négative (vide). De nombreux produits Gast peuvent fonctionner soit comme compresseur, soit comme pompe à vide, ce qui permet aux équipementiers et aux utilisateurs finaux d'utiliser une seule et même plateforme pour plusieurs fonctions.

Gast propose à la fois des technologies sans huile et des technologies lubrifiées à l'huile. Les produits sans huile sont généralement choisis pour les applications nécessitant de l'air propre et sec ainsi qu'un entretien minimal, tandis que les technologies lubrifiées à l'huile peuvent offrir des avantages en termes de durabilité et de performances dans des environnements industriels exigeants.
