摘要 |
The invention relates to a filter or filtering element used alone or in juxtaposition with other elements of the same kind, for the purpose of purifying a fluid, which element constitutes an enclosure acting as a container for the pulverulent product and comprises a substantially rigid surrounding member optionally rigidly connected to a cover and base through which the fluid to be treated may pass, and is characterised in that at least one of the walls of said enclosure is made of a vinyl material which contracts under heat so as to enable the volume of the enclosure to be reduced after it has been completely filled with pulverulent product. |
