More Information
Summary:PURPOSE: An exhaust fan for a lubricating oil storage tank is provided to completely discharge gas to an exhaust port without leaking, and to reduce manufacturing costs by simplifying the structure of the fan. CONSTITUTION: An exhaust fan for a lubricating oil storage tank comprises a casing(10), a pair of side covers(20), a gas discharging unit, and a gear cover(50). The casing has an exhaust port and a suction port. The gas discharging unit has a pair of rotors(31,32). The rotors push gas to the exhaust port. Protrusions are formed on the outer surface of the rotors. The gear cover forms a sealed space by covering gears(40) of a drive shaft(31a) and a driven shaft of the rotors.
