Abstract

La présente invention a pour objet un filtre à air. Elle est caractérisée en ce que ce filtre comprend un châssis élastique, un corps creux formé de papier plissé et des couvercles d'extrémités, ces éléments étant liés ensemble au moulage de façon à former une structure monobloc flexible qui conserve sa forme et qui possède les caractéristiques d'efficacité de l'agent de filtrage constitué par le papier. Elle se rapporte à des épurateurs d'air pour moteurs.The present invention relates to an air filter. It is characterized in that this filter comprises an elastic frame, a hollow body formed of pleated paper and end covers, these elements being linked together to the molding so as to form a flexible one-piece structure which retains its shape and which has the same characteristics. efficiency characteristics of the filtering agent constituted by the paper. It relates to air cleaners for engines.
