An improved filter pad assembly, for supporting a filter pad, used in conjunction with a filter system having a pumping unit to filter a contaminated fluid. Included in the filter pad assembly are a filter pad support member, a sealing member, and securing means for maintaining the filter pad support member and sealing member in a closed operative position during the filtering process such that a substantially fluid-tight seal is created therebetween. Thus, the contaminated fluid is prevented from exiting the filter pad assembly withoutpassing through the filter pad. The filter pad assembly may be defined to include, or not include, the filter pad. The filter pad assembly and filter pad also have a one-way guided configuration that ensures the filter pad is properly oriented within the assembly. Three preferred embodiments of the filter pad assembly of the present invention are disclosed.

Ensemble tampon filtreur amélioré servant à soutenir un tampon filtreur, conjointement avec un système de filtration doté d'un système de pompage pour filtrer un fluide contaminé. L'ensemble est constitué d'un élément de soutien du tampon filtreur, d'un élément d'étanchéité ainsi que d'un dispositif de fixation pour maintenir l'élément de soutien et l'élément d'étanchéité en position de fermeture au cours du processus de filtration, de façon à être essentiellement étanche aux fluides. On évite ainsi que le fluide contaminé ne s'échappe de l'ensemble tampon filtreur sans passer par le tampon filtreur. Cet ensemble peut être défini de manière à inclure, ou à ne pas inclure, le tampon filtreur. En outre l'ensemble tampon filtreur et le tampon filtreur présentent une configuration à sens unique, permettant de s'assurer que le tampon filtreur est adéquatement orienté à l'intérieur de l'ensemble. Trois modèles privilégiés de cet ensemble tampon filtreur sont visés par la présente invention.
