摘要:
A centrifugal filter assembly for filtering particulates from engine oil includes a housing with a threaded connector. A filter disposed within the housing is rotatable relative to the housing about an axis of rotation. The filter has an inlet and an outlet for the oil. A filter head includes a mating threaded connector configured to mate with the housing threaded connector. The filter head includes a venturi section in communication with the outlet. The venturi section is configured to create a vacuum within the housing for drawing oil through the outlet. A brushless direct current motor carried by the filter head has a rotatable output shaft coupled with the filter for rotating the filter about the axis of rotation. A controller carried by the filter head controls operation of the motor. The controller includes a printed circuit board disposed within the filter head which carries the motor.
