ABSTRACT:
A filter cartridge includes a filter housing having a main housing portion and a removable end closure defining a filter element cavity. The main housing portion includes an open annular end having an in-turned annular lip with a series of receiving slots formed in the inner surface of the lip. A filter element is disposed within the housing cavity and includes an end cap with a series of axially-extending drive pins, and an axially-extending stand-off device, where the drive pins are axially longer than the stand-off device. A mounting hub having a central threaded collar for attachment to a base is disposed between the outer surface of the end cap and the lip of the main housing portion. The mounting hub includes a series of orientation through-holes which correspond to the location of the drive pins on the end cap. The orientation pins project through the through-holes in the mounting hub and are received in the receiving slots in the main housing portion to fix the mounting hub against rotation within the filter housing. The housing can then be spun-on to the base. The axially-extending stand-off device separates the mounting hub from the end cap to provide a flow path therebetween, and allow fluid to flow through outer through-holes in the mounting hub to the peripheral region of the filter element. The fluid can then flow radially-inward through the element, and through a central through-bore in the collar of the mounting hub to the base.
