1. A method comprising:
establishing a fluid flow of particle-laden fluid in a primary fluid passageway of a machine that is defined by opposing first and second walls;
filtering a first portion of the particle-laden fluid by passing the particle-laden fluid over an undulating separator body having one or more separator openings that extends over at least one bleed hole through the first wall, the first portion of the particle-laden fluid filtered by the first portion of the particle-laden fluid bending around an edge of the undulating separator body at the one or more separator openings and flowing into an auxiliary fluid passageway, wherein a second portion of the particle-laden fluid passes over the undulating separator body without being filtered by the undulating separator body; and
directing the first portion of the particle-laden fluid that is filtered to one or more downstream components of the machine.
