Filter base system and filter assembly

A filter base system configured to couple a filter assembly to a machine, the filter base system comprising:

• a mounting bracket configured to be coupled to a machine;
• an extension coupled to the mounting bracket, the extension being configured to provide clearance between the machine and the filter assembly;
• and
• a filter assembly coupler associated with the extension, the filter assembly coupler being configured to receive a portion of a filter element, the filter assembly coupler including:
• an inlet passage configured to provide flow communication from the machine to the filter element, the inlet passage having a longitudinal axis;
• an outlet passage configured to provide flow communication from the filter element to the machine, the outlet passage having a longitudinal axis;
• a receiver configured to receive an end portion of a filter element, the receiver including a receiver passage having a longitudinal axis and extending transverse to the longitudinal axes of the inlet and outlet passages;
• and
• a base plug configured to be received in a first end of the receiver passage opposite a second end of the receiver passage configured to receive the end portion of the filter element,
• wherein the base plug includes a base plug body configured to provide a seal between the base plug and the receiver passage,
• wherein the base plug body includes a plug surface extending at an oblique angle with respect to the longitudinal axis of the receiver passage, and
• wherein the plug surface is configured to cooperate with the end portion of the filter element, to ensure that the filter element is installed in the correct orientation relative to the filter base.

A filter assembly y comprising:

• a filter base including a filter base system configured to couple a filter assembly to a machine, the filter base system including:
• a mounting bracket configured to be coupled to a machine;
• an extension coupled to the mounting bracket, the extension being configured to provide clearance between the machine and the filter assembly;
• and
• a filter assembly coupler associated with the extension, the filter assembly coupler being configured to receive a portion of a filter element, the filter assembly coupler including:
• an inlet passage configured to provide flow communication from the machine to the filter element, the inlet passage having a longitudinal axis;
• an outlet passage configured to provide flow communication from the filter element to the machine, the outlet passage having a longitudinal axis;
• a receiver configured to receive an end portion of a filter element, the receiver including a receiver passage extending transverse to the longitudinal axes of the inlet and outlet passages;
• and
• a base plug configured to be received in a first end of the receiver passage opposite a second end of the receiver passage configured to receive the end portion of the filter element, wherein the base plug includes a base plug body configured to provide a seal between the base plug and the receiver passage, the base plug body including a plug surface configured to cooperate with the end portion of the filter element such that orientation of the filter element with respect to the filter base depends on orientation of the base plug in the receiver;
• a canister having an open end, a closed end, and being configured to be coupled to the filter base;
• and
• a filter element configured to be received in the canister and coupled to the receiver of the filter base, the filter element including:
• a tubular member having a longitudinal axis and including an end portion at least partially defining an inlet port configured to provide flow communication with the inlet passage of the filter assembly coupler, and at least partially defining an outlet port configured to provide flow communication with the outlet passage of the filter assembly coupler;
• and
• a filter medium configured to filter particles from fluid passing through the filter element, the filter element being configured such that fluid passing through the filter assembly from the inlet passage of the filter assembly coupler to the outlet passage of the filter assembly coupler passes through the filter medium.
