A multiple action filter with components structured in a "cord" or also a "ribbon" form is in the first case filter element to be inserted in a conduit, and in the second case, besides being inserted, it may also form conduit itself. The principles of action are basically dynamic: adhesion, cohesion, capillarity and chemical, physical, magnetic, electric or others which may be exploited wholly or partially. |
