Abstract

L'invention concerne une combinaison de filtres coniques constituée d'un premier filtre (1) et d'un second filtre (2). Les premier et second filtres sont tous deux coniques et assemblés l'un avec l'autre. Du fait de sa structure conique, le filtre permet un écoulement d'air plus raisonnable pendant son processus de travail, ce qui augmente sa durée de vie. La combinaison de filtres de même standard peut être utilisée dans un équipement pour faciliter une installation et son entretien.
