However, it is important to note that magnetic filters are only effective in capturing ferrous metal contaminants and cannot remove non-metallic impurities.
Centrifugal oil filters
Centrifugal oil filters operate using centrifugal force to separate contaminants from the engine oil. As the oil enters the filter, it is forced through a spinning rotor, which creates a strong centrifugal force that pushes the contaminants outward against the walls of the filter housing. The clean oil is then allowed to pass through and return to the engine.
Centrifugal oil filters are effective in removing both large and small contaminants, including non-metallic particles. However, they may be more complex and require more frequent maintenance than other filter types.
Sedimentation oil filters
Sedimentation oil filters, also known as gravity bed filters, rely on gravity to separate contaminants from engine oil. As the oil flows through the filter, the contaminants settle at the bottom due to their higher density. The clean oil then rises to the top and exits the filter, returning to the engine.
Sedimentation oil filters are generally less effective than other filter types, as they do not have a specific filter media to trap contaminants. They are also more susceptible to clogging and may require more frequent maintenance.
