1. A filter assembly for filtering contaminants from a fluid stream, the filter assembly comprising:
a. a housing defining a chamber and an opening which communicates with the chamber, the chamber having an inlet arranged to receive a fluid stream including entrained contaminants, and an outlet through which the fluid stream can exit the chamber following removal of contaminants;
b. a filter element having a first end, a second end, a passage extending along the element between the first and second ends and a filter media component extending around the passage, the filter element being locatable within the chamber in a flow path extending between the inlet and the outlet so that fluid flowing along the flow path is directed through the filter media component;
c. in which the housing opening is dimensioned so that the filter element can pass through the opening for location in the chamber, and in which the filter assembly comprises a cover which can be coupled to the housing to close the opening and secure the filter element within the chamber;
d. at least one first alignment assembly having a first alignment component and a second alignment component, one of the first and second alignment components being provided by the housing and disposed within the chamber, and the other being provided by the filter element and comprising a flange projecting radially outward, away from an outer surface of the filter media component around an entire outer perimeter of the filter element and describing an outermost circular perimeter of the filter element, the flange including an alignment component comprising a plurality of recesses extending inwardly from a circular perimeter of the flange, the first and second alignment components cooperating to rotationally orient the filter element within the chamber; and
e. at least one second alignment assembly having a first alignment component and a second alignment component, one of the first and second alignment components being provided by the housing and disposed within the chamber, and the other being provided by the cover, the first and second alignment components cooperating to rotationally orient the cover relative to the housing and so to the filter element.
