An air delivery apparatus which has a low profile by virtue of an angled/offset air outlet. The apparatus provides superior air delivery performance which is customizable to any application by selection of orifice patterns in an interchangeable nozzle insert, and the flexibility of easily changing the nozzle inserts to suit the application, while maintaining a constant amount of pressurized air energy input. The low profile enables use of the apparatus in applications where space between machinery and products is limited, where other air delivery apparatuses would not fit. Various embodiments of low profile, angled/offset air delivery apparatus are disclosed—including designs with one, two or four exit openings, where the airflow path inside the apparatus turns at a 90 degree angle in order to minimize the height of the apparatus. The single-opening designs include both “left-hand” and “right-hand” models, and the dual-opening designs include both offset and opposed air streams.
