An air conveyor for handling workpieces in a food grade environment has a cylindrical pipe with an elongated slot that extends along an axial length of the pipe. A track is snap fit in the elongated slot and has a base for supporting the workpieces. The base has air vents that provide directional airflow for pushing the workpieces along an axial length of the track on a cushion of air. A movable hanger assembly supports the pipe from above and captures the workpieces in the track.
