Abstract

A separator has a first inlet arranged to receive a fluid stream, and first and second separation stages coupled together in series; A pump coupled to the second separation stage generates an area of reduced pressure to draw the fluid stream through the first and second separation stages. One of the stages includes a variable impactor separator comprising a first chamber arranged to receive the fluid stream, and a second chamber coupled to the first chamber through an aperture to accelerate the first fluid stream. The stream is incident upon an impaction surface to separate contaminants from the fluid stream. An actuator adjusts the open area of the aperture according to a pressure differential between fluid pressure in the first chamber and a reference fluid pressure in a third chamber. The other of the separation stages is a second variable impactor separator or a filter media.
