Abstract
A filter of a filter device has a filter housing with a connecting side provided with a connecting element for detachably connecting the filter to a filter head of the filter device by a rotational and/or insertion movement relative to an imaginary connecting axis of filter and filter head. The filter housing has an inlet for fluid to be purified and an outlet for purified fluid. An outer seal seals a connection of the filter with the filter head relative to the environment. The outer seal is circumferentially continuous relative to the connecting axis. A closure element is provided to close off, when the filter is connected to the filter head, a fluid drain in the filter head provided for draining fluid when removing the filter from the filter head. The outer seal is acting sealingly at least in radial direction relative to the connecting axis.
