An air manifold system that includes an improved air nozzle is provided. In one embodiment, the nozzle has an inlet and an outlet. The inlet of the nozzle may be shaped to conform to the curved outer surface of a main body of the air manifold, and may be welded thereto. The nozzle includes a variable section extending from the nozzle inlet to an intermediate transition point along the length of the nozzle, which has a converging inside diameter, which compensates for flow losses due to cornering. A resistive section extends from the transition point to the outlet, and has a generally constant diameter which is less than the inside diameter of the variable section measured at the nozzle inlet. In one embodiment, the length of the resistive section is less than the length of the variable section.
