Abstract

L'invention concerne un élément filtrant destiné à être disposé dans un conduit (18) d'une installation de climatisation ou de ventilation d'un véhicule à moteur, comprenant un élément de couvercle (1) qui peut être associé à un orifice du conduit pour le fermer, un élément frontal (2) qui peut être tourné vers le fond du conduit (19) lors de l'insertion de l'élément filtrant dans le conduit (18), un cadre de filtre (3) et un soufflet (4) qui est au moins partiellement entouré par le cadre de filtre (3). Selon l'invention, pour obtenir un élément filtrant qui peut se monter rapidement et sans problème dans le conduit d'une installation de climatisation ou de ventilation, l'élément filtrant est caractérisé en ce que l'élément frontal (2) est pourvu d'au moins un évidement et/ou creux dans lequel un élément de guidage (20) dépassant du fond du conduit (19) peut dépasser sans que l'élément filtrant soit guidé par l'élément de guidage (20) lors de l'insertion et/ou sans que des parties de l'élément frontal (2) touchent l'élément de guidage (20).
