Abstract
A magnetic nano-lubricant filtration system includes a housing having a peripheral wall, a cavity defined by a space within the peripheral wall, a plurality of helical baffles on an inner surface of the peripheral wall, an inlet at a bottom end of the peripheral wall and an outlet at a top end of the peripheral wall; and a filter cartridge removably disposed within the cavity, the filter cartridge including a strainer, an electret nanofiber pre-filter above the strainer, a functionalized mesh filter above the electret nanofiber pre-filter, and an array of magnets above the functionalized mesh filter.
