Abstract: A corrosion-inhibiting device includes a housing having an inlet and an outlet, and a corrosion-inhibiting material positioned within the housing downstream of the inlet. At least a portion of the corrosion-inhibiting material is released into a fluid stream flowing toward the outlet. The corrosion-inhibiting device also includes an impeller supported for rotation within the housing and an oxidation removal means movable in response to rotation of the impeller and engageable with the corrosion-inhibiting material to remove oxidation formed on the corrosion-inhibiting material.

Abstract: A fluid filter (1) comprises a housing (3) provided with a fluid inlet (11) and a fluid outlet (19), filter means (45) being mounted in the house (3) between the fluid inlet (11) and the fluid outlet (19) to filter fluid flowing through the housing (3). Actuation means (43) is provided to move the filter means (45), in use, within the housing (3) to dislodge particles of filtered material from the filter means (45) so as to clean the filter means (45). A filter assembly comprising a plurality of such filters is also provided.
