Title
(EN) FILTER FOR AIR CLEANER
(FR) FILTRE POUR PURIFICATEUR D'AIR
Abstract
(EN)
A filter medium is constituted by a long piece of filter paper which is folded so that crests and troughs are alternately formed therein, and the filter medium is provided with a spacer which is inserted so that a predetermined spacing is maintained between adjacent crests and between adjacent troughs. The filter medium is curved so that each crest and trough is directed radially. This filter medium is placed in a housing provided with an air inlet and an air outlet, and a cushioning material is inserted at the contact areas between the housing and the filter medium.
(FR)
Un filtre est constitué par une longue pièce de papier filtre plissé de manière à y former des crêtes et des vallées en alternance, et le filtre est pourvu d'une entretoise qui est insérée de sorte à maintenir un écartement prédéterminé entre des crêtes adjacentes et entre des vallées adjacentes. Le filtre est courbé de sorte que chaque crête et chaque vallée soient dirigées radialement. Ce filtre est placé dans une enceinte pourvue d'une entrée d'air et d'une sortie d'air, et un matériau amortisseur est inséré au niveau des zones de contact entre l'enceinte et le filtre.
