ABSTRACT:
A filter unit including a housing element having a first and a second inlet for fluid and a first and a second outlet for fluid, flow passages defined in the housing defining a first path of flow for fluid between the first inlet and the first outlet of the housing, a flow passage defined in said housing defining a second path of flow for fluid between the second inlet and the second outlet of the housing, and a filter member in housing being capable of filtration to remove particles of dimensions greater than 5 micrometers, the second path of flow including a path through the filter and a by-pass about the filter having a resistance to flow of fluid no greater than that of the filter whereby in normal use a proportion only of fluid passing through the second flow path passes through the filter, provides fine filtration for an internal combustion engine and is attachable to a conventional engine filter mount.
