  • Patent number: 5057658
    Abstract: An apparatus for filtering and recirculating oil used in a vacuum pump is disclosed. The filtration device comprises first and second valves permitting, respectively, addition and deletion of oil from the system. A plurality of filter elements are provided to remove particulate contamination from the oil. In a preferred embodiment, the vacuum pump is situated in an enclosure which retains therein the latent heat produced by the vacuum pump. Alternatively, an oil heater may be provided. The oil is preferably maintained at a temperature of greater than about 40.degree. C., so that the particulates entrained therein remain in a sludge.
