FILTER ELEMENT AND MANUFACTURE THEREOF |
| 摘要 |
A filter element comprises a relatively rigid fluid-permeable cylinder (5), around which is provided a body (7) of non-woven fibrous filter material. A jacket (6) of permeable material is positioned around the outer surface of the filter material, and is heat-shrunk onto the filter material in order to hold this under substantially uniform radial compression over the whole of its area. |
