Abstract: The present invention relates to an oil filtration system for purifying oil present in a reservoir, the system comprising a system inlet for receiving an inlet flow of contaminated oil from said reservoir, a system outlet for releasing an outlet flow of purified oil to said reservoir, a vacuum housing which is in fluid communication with the system inlet and the system outlet, where the vacuum housing comprises an oil filter arranged in-side said housing, which oil filter is adapted to receive the contaminated oil and to release filtered oil, a first pumping unit which is arranged upstream of the vacuum housing, where the first pumping unit is adapted to provide a flow of contaminated oil in a direction from the system inlet to an inlet of the vacuum housing at a fixed pumping flow rate, a second pumping unit which is arranged downstream of the vacuum housing, where the second pumping unit is adapted to provide a flow of purified oil in a direction from an outlet of the vacuum housing to the system outlet at

Abstract: The present invention relates to an oil filtration unit comprising a housing, which comprises a housing inlet adapted to receive contaminated oil from the surroundings and to release the contaminated oil to an inner opening of the housing, and a housing outlet adapted to release filtered oil to the surroundings, where the inner opening of the housing is defined by an inner bottom surface, an inner top surface, and at least one inner side surface and comprises an oil filter for filtering the contaminated oil, said oil filter being arranged inside the inner opening of the housing, where said oil filter comprises a filter inlet defined by an outer surface of the oil filter, an inner filter volume adapted to receive filtered oil, and a filter outlet inside said housing providing fluid/liquid communication between the inner filter volume and the housing outlet in order to release the filtered oil from the inner filter volume, and where said oil filter further comprises a top and a bottom end surface relative to th

Abstract: In a filtering device comprising one or more filtering elements (1) having in principle co-axially disposed through-going apertures (4) for the passage of fluid, the individual filtering element (1) consists of two identical filtering discs (2, 3) which abut each other closely along their outer peripheral edges, and which at the sides facing away from each other are formed in such a way that several filtering elements (1) abut each other closely along the inner edges adjacent to the aperture (4).
