  • Key system to ensure correct use of inserts
    Patent number: 11786850
    Abstract: An oil filter for an oil filtration system. The filter is configured for insertion into an oil filtration unit. The filter comprises a central opening extending along a central axis of the filter, at least one second physical structure having a second cross sectional shape and a predefined longitudinal length in relation to the central axis of the filter, and an inner periphery of the second physical structure being arranged to mate with the outer periphery of the first physical structure allowing the filter to reach its correct insertion position in the oil filtration unit by the second physical structure at least partly surrounding the first physical structure. The end surface of the filter relative to the central axis of the filter comprises the second physical structure, and the second physical structure comprises a material configured to serve as a filtering material of the filter.
