Abstract:
The present relates to an oil filtration system (1) comprising an oil filtration unit (2), an oil filter (13) having a central opening (15) extending along a central axis (B) of the oil filter (13), the oil filtration unit (2) being provided with at least one first physical structure (18,18′,18″) having a first cross-sectional shape and a predefined longitudinal length (x) in relation to the central axis (A) of the oil filtration unit (2), the oil filter (13) being provided with at least one second physical structure (23,23′,23″) having a second cross sectional shape and a predefined longitudinal length (y) in relation to the central axis (B) of the oil filter (13) and an inner or outer periphery of the second physical structure (23,23′,23″) being arranged to mate with the outer or inner periphery of the first physical structure (18,18′,18″) allowing the oil filter (13) to reach its correct insertion position in the oil filtration unit (2), where at least one of the end surfaces (28,29,31) of the oil filter (13) relative to the central axis (B) of the oil filter (13) comprises the at least one second physical structure (23,23′,23″).
