Abstract

A method of providing clean air to a workpiece comprises positioning the workpiece adjacent to a first opening in a conduit. The conduit includes a central segment and a peripheral segment having, respectively, the first opening and a second opening disposed at opposite ends of the conduit. The peripheral segment surrounds the central segment such that the first opening is substantially coplanar with the second opening. A laminar flow of air is created through the conduit in a direction away from the second opening and toward the first opening. The air flow is filtered through a HEPA filter supported within the conduit.
