Abstract
A twin filter comprises two filter housings 11 and 12 which are selectively supplied by a switchover device having a housing 13 with a liquid to be filtered. A closure slide 42 is movable in the housing 13 into two closed positions in which it blocks the supply of the liquid to one of the two filter housings. The closure slide 42 is released from its closed position for displacement into the respective other closed position by a releasing device in the form of a lifting device 48.
