ABSTRACT:
In order to replace a dirty filter in a cabinet, the clean filter is introduced in an upper slot of the cabinet until it comes in contact with the paddle of switch. The clean filter is thus superposed on the dirty filter, and the dirty filter is retracted through the lower slot of the cabinet. The replacement of the filter is done without stopping the machine.
