ABSTRACT OF THE DISCLOSURE An oil filter is disclosed which comprises a housing opened at one end, a first separator unit disposed in the housing for removing solid contaminants from an oil and a second separator unit for removing gaseous contaminants. The first separator unit includes cylindrical primary and secondary filter elements aligned with each other, the secondary filter element being finer than the primary filter element. The second separator unit is accommodated within the space defined by an inner periphery of the primary filter element and includes a cylindrical casing, a cyclone disposed within the casing for defining a chamber arranged to generate a vortical flow of the oil introduced therein to thereby separate a gas-rich oil which gathers in an axially central portion of the chamber, the cyclone having a plurality of pores formed therethrough, and a removal pipe extending along an axis of the chamber and having a plurality of orifices, the removal pipe having a portion projecting from the cyclone. A pipe extends within the secondary filter element for defining a circular space between an inner periphery of the secondary filter element and the pipe, and communicates with the chamber through the pores for leading an oil containing little gaseous contaminants outside the housing. A duct is disposed in the pipe and comprises a vertical section and a horizontal section, the vertical section receiving an end of the portion of the removal pipe while the horizontal section penetrates a wall of the pipe to open in the circular space for discharging the gas-rich oil.
