Abstract: A filter assembly 7 for separating contaminants from a fluid stream is described. The filter assembly 7 comprises a filter element 58 which is locatable within chamber 19 in a flow path extending between inlet 54 and outlet 56. The filter element 58 comprises a filter media component 60, and the filter element is locatable within the chamber 19 in the flow path so that fluid flowing from the inlet 54 to the outlet 56 is directed through the filter media component. The filter assembly 7 comprises at least one first alignment assembly having a first alignment component 64a provided by the housing portion 21c and disposed within chamber 19, and a second alignment component 66a provided by the filter element 58. The first and second alignment components 64a and 66a cooperate to rotationally orient the filter element 58 within the chamber 19.

Abstract: A separator for separating contaminants from a fluid stream has first and second chambers coupled by an aperture through which fluid can pass. An actuator can adjust the crossectional area of the aperture according to a pressure differential between the first chamber and a pressure reference. An impaction surface can deflect the first fluid stream after it enters the second chamber such that contaminants are separated from the stream. A pump generates a pressure differential across the aperture. It includes a third chamber having a second inlet for receiving a second fluid stream into the third chamber. The second inlet includes a convergent nozzle for accelerating the second fluid stream, and a third inlet for receiving the first fluid stream downstream of the impaction surface, the third inlet being arranged relative to the second inlet such that the second fluid stream can entrain and accelerate the first fluid stream.
