An apparatus comprising:
- an air cap configured to be affixed to a nozzle assembly as a downstream facing component of the nozzle assembly, wherein the air cap includes a plurality of air wipe passages with outlets defined in a circumferential direction around a downstream facing surface of the air cap, wherein the plurality of air wipe passages define a first ring of air wipe passages with outlets on the downstream facing surface of the air cap, and a second ring of air wipe passages with outlets on the downstream facing surface of the air cap, wherein the outlets of the second ring of air wipe passages are radially inward on the downstream facing surface from the outlets of the first ring of air wipe passages, wherein the downstream facing surface of the air cap includes a circumferentially extending series of steps, each step defining a circumferentially facing planar outlet face from which one or more of the outlets of the plurality of air wipe passages emerge, wherein each circumferentially facing planar outlet face includes one outlet of the first ring of air wipe passages and one outlet from the second ring of air wipe passages.
