1. A method for drying, comprising:

  • with a fan positioned within a confined space, generating an air stream within the confined space;

    positioning a terminal lip surface of the confined space relatively stationary with respect to a substantially flat work surface to be dried, wherein the terminal lip surface is further defined by a periphery of the confined space adjacent to a terminus thereof and being offset a substantially constant distance in the range of two to five inches from the work surface;

    exhausting the air stream from the confined space into a downstream zone defined between the confined space and the work surface and substantially bounded by the terminal lip surface;

    directing the exhausted air stream across the work surface to be dried; and

    exhausting the air stream from the downstream zone into ambient air space external of the terminal lip surface as an air stream positioned adjacent to the work surface.
