Title
(EN) NITROGEN GAS GENERATION DEVICE
(FR) DISPOSITIF DE PRODUCTION D'AZOTE GAZEUX
Abstract
(EN)
The present invention relates to a nitrogen generator, and more particularly a nitrogen generator comprising: an inlet member equipped with an inlet port; a discharge member equipped with a discharge port; a first pipe that is connected to the above inlet member; a second pipe that is connected to the above discharge member; hollow fiber membranes that are connected to the first pipe and the second pipe, wherein the first pipe and the second pipe are separated from each other thereby enabling the miniaturization of the product.
(FR)
L'invention concerne un générateur d'azote, plus précisément un générateur d'azote comprenant: un élément d'admission équipé d'un port d'admission; un élément d'évacuation équipé d'un port d'évacuation; un premier tuyau relié à l'élément d'admission ci-dessus; un second tuyau relié à l'élément d'évacuation ci-dessus; des membranes fibreuses creuses reliées au premier tuyau et au second tuyau, les premier et second tuyaux étant séparés l'un de l'autre, ce qui permet la miniaturisation du produit.
