A filter (10) for removing undesired materials from a fluid, such as used cooking oil, includes a filter envelope (11) including first and second panels (12, 14). The first panel (12) has a permeability greater than that of the second panel (14). The first panel (12) of the filter envelope (11) may be formed of a filter pad and the second panel (14) may be formed of a filter paper and may enclose a metal spacer grid (18). When the filter (10) is connected to a pump for drawing the oil through the filter (10), the flow of the oil is directed selectively through the filter pad (12), whereby undesired materials are removed from the oil. The filter (10) provides for efficient flow of the oil to be filtered while removing undesired materials therefrom.
Filtre (10) conçu pour retenir des matières indésirables dans un fluide, par exemple dans de l'huile de cuisson usée, et comprenant une enveloppe filtrante (11) elle-même composée d'un premier et d'un second panneau (12, 14). Le premier panneau (12) possède un indice de perméabilité plus élevé que le second panneau (14). Le premier panneau (12) de l'enveloppe filtrante (11) peut être constitué par un tampon filtrant, le second panneau (14) par un papier filtrant renfermant éventuellement une grille métallique (18). Lorsque le filtre (10) est relié à une pompe aspirante, l'huile est aspirée sélectivement à travers le tampon filtrant qui retient les matières indésirables présentes dans l'huile. Le filtre (10) facilite le passage de l'huile à filtrer tout en arrêtant les matières indésirables présentes dans l'huile.
