  • Patent number: 10293283
    Abstract: A filter for separating contaminants from fluids. The filter includes stages of differing materials arranged one after another wherein the first stage blocks and captures contaminants of a selected size and passes everything smaller than this selected size. The next stage captures contaminants of a selected size which is smaller than those blocked by the first stage. The subsequent stages capture smaller and smaller contaminants. The layers comprise various materials including stranded meshes, fibrous tissues, metallic screens and ceramic discs and tubes. Some of the ceramic discs and tubes include a downstream coating to capture further contaminants such as water droplets.
