Title
(EN) DEBRIS-FILTER MATERIALS PRINCIPALLY FOR AUTOMATIC SWIMMING POOL CLEANERS
(FR) MATÉRIAUX DE FILTRES À DÉBRIS PRINCIPALEMENT POUR DES NETTOYEURS AUTOMATIQUES DE PISCINE
Abstract
(EN)
Debris filters for automatic swimming pool cleaners may be formed of metal, carbon fibers, or composites more rigid than soft nylon bags. In at least one version, the filter may be made of, or include, steel or stainless steel. Non-uniform sizes, densities, and/or shapes of openings in the filtration material may be created to provide different levels of filtration in a single device.
(FR)
Des filtres à débris pour des nettoyeurs automatiques de piscine peuvent être constitués de métal, de fibres de carbone ou de composites plus rigides que les sacs en nylon souples. Dans au moins une version, le filtre peut être constitué, ou comprendre, de l'acier ou de l'acier inoxydable. Des tailles, des densités et/ou des formes non uniformes d'ouvertures dans le matériau de filtration peuvent être créées pour fournir différents niveaux de filtration dans un seul dispositif.
