  • Rechargeable filter
    Patent number: 5716521
    Abstract: A rechargeable filter comprises first and second spaced particle-retaining meshes in which the first mesh (64) is continuous and forms a series of "V" shapes, and the second mesh comprises a number of closed "V"-shaped mesh elements (68), each second mesh element projecting into one "V" of the first mesh. The meshes are spaced at a constant distance by rigid projections (70) which also laterally space the upper parts (72) of the second mesh elements so that particles of filter material (74) can be loaded and unloaded.
