Abstract

Filtre à noyau tubulaire perforé et plusieurs couches de fils enroulées sur ce noyau. La couche située le plus à l'extérieur peut retenir des particules ayant des dimensions inférieures à celles des particules retenues par la couche située le plus à l'intérieur. Les particules pouvant être retenues par la couche extérieure ont des dimensions comprises entre 1 et 25 micromètres, alors que celles retenues par la couche intérieure ont des dimensions comprises entre 25 et 100 micromètres. Domaine d'application : épuration de liquides, etc.Filter with perforated tubular core and several layers of wires wound on this core. The outermost layer can retain particles of smaller dimensions than the particles retained by the innermost layer. The particles that can be retained by the outer layer have dimensions between 1 and 25 micrometers, while those retained by the inner layer have dimensions between 25 and 100 micrometers. Field of application: cleaning of liquids, etc.
