<p>An annular filter cartridge (26) through which air passes radially as the air moves in a generally toroidal path within an enclosed housing (12) due to rotation of e.g. a computer tape disc (10), mounted adjacent to the cartridge within the housing. The cartridge includes a rigid annular body supporting an annular sheet (28) of filter material in a generally conical configuration within the annular body. The body portion is initially formed as two separate, mating parts (30,32) which clamp the sheet of filter material about its inner and outer peripheries when they are joined together. </p> |
