Abstract
(DE)
Eine Filtervorrichtung mit einer Mehrzahl von Filterelementen (2), die in einem Filtergehäuse (4) mit einem Filtereinlaß (6) für ein zu filtrierendes Fluid (8) und einem Filterauslaß (10) für das gefilterte Fluid (12) aufnehmbar sind, wobei die Filterelemente (2) für eine Filtration oder Rückspülung in beiden Richtungen durchströmbar sind, ist dadurch gekennzeichnet, dass zwischen zumindest einem Teil der Filterelemente (2) und dem Filterauslaß (10) je ein weiteres Filterelement, insbesondere in Form eines Feinfilterelementes (14), in Bereichen des Strömungsweges des Fluids angeordnet ist, das von dem jeweiligen, dem weiteren FiIterelement (14) zugeordneten Filterelement (2) vorfiltriert ist.
(EN)
A filter device having a multiplicity of filter elements (2) which can be held in a filter housing (4) having a filter inlet (6) for a fluid (8) to be filtered and having a filter outlet (10) for the filtered fluid (12), wherein the filter elements (2) can be traversed by flow in both directions for filtration or back-flushing, is characterized in that, between at least a part of the filter elements (2) and the filter outlet (10), in each case one further filter element, in particular in the form of a fine filter element (14), is arranged in regions of the flow path of the fluid which is pre-filtered by the respective filter element (2) assigned to the further filter element (14).
(FR)
L'invention concerne un dispositif de filtration comprenant une pluralité d'éléments filtrants (2) qui sont logés dans un carter de filtre (4) présentant une entrée de filtre (6) pour un fluide à filtrer (8) et une sortie de filtre (10) pour le fluide filtré (12), les éléments filtrants (2) pouvant être traversés dans les deux directions, pour une filtration ou pour un lavage à contre-courant. L'invention est caractérisée en ce qu'il est prévu entre au moins une partie de l'élément filtrant (2) et la sortie de filtre (10), respectivement, un autre élément filtrant, en particulier sous forme d'élément filtrant fin (14), dans des zones de parcours d'écoulement du fluide, lequel est préfiltré par l'élément filtrant (2) associé, respectivement, à l'autre élément filtrant (14).
