A particulate filtration system including a frustoconical-shaped filtration element, a housing enclosing the filtration element and coaxial therewith, an inlet, and an outlet. The filtration element has a closed first end and a larger oppositely-disposed open second end. The housing has a first closed end, a larger oppositely-disposed open second end, and a frustoconical-shaped wall therebetween and surrounding the filtration element. An annular-shaped passage is defined by and between the filtration element and the housing. The inlet is located at the second end of the housing and is fluidically connected to the annular-shaped passage. The outlet is located at the second end of the filtration element and coaxial with the inlet. The outlet defines an outlet passage with a frustoconical or arcuate shape and a cross-sectional area that decreases along the flow path in a direction away from the filtration element.
