Patent attributes
An inline virtual impactor comprising an outer housing having a housing inlet, a housing inner surface, a major flow outlet and a minor flow outlet; a flow accelerator member disposed in the upstream portion of the outer housing; and a flow stabilizer member disposed within the outer housing downstream of the flow accelerator member, wherein the disposition of the flow accelerator creates an annular flow passage between the flow accelerator and the outer housing, and wherein a flow divider that is at least partially downstream of the flow stabilizer member effects splitting of the flow stream entering the housing into major and minor flows. The minor flow comprises primarily particles having a size greater than a cutpoint size and the major flow comprises primarily particles smaller than the cutpoint size. The inline virtual impactor may further comprise an aspiration section located upstream of the flow accelerator member.
