Definitions

  • These cartridges generally comprise a container of plastics material which houses a filter material which is generally granular.
  • the container is in turn provided with at least one inlet opening for the fluid to be filtered and at least one outlet opening for the filtered fluid, both provided with retaining means arranged to retain the filter material within the container.
  • the retaining means to which the invention relates are those disposed at the outlet opening and are generally embodied as grids (the term grid is understood to include nets, foam, membranes, calibrated holes and the like) with a mesh whose narrowness depends on the filter material to be retained.
