Abstract: A rigid, one piece nozzle for blast aerators is configured to be mounted in a variety of operating orientations within and upon applications of widely varying shapes and geometry. The generally triangular nozzle comprises a flat base and a spaced-apart, arcuate top, secured to the base by a pair of opposed side walls. An inlet orifice in the flat body portion is internally configured like a truncated cone, and communicates with the nozzle discharge orifice thorough the hollow interior of the nozzle. The inlet is conical to permit the feed pipe to be mated and welded to it once the parts are properly oriented by the installer. An airtight seal results during welding, as the void between the pipe periphery and the circumference the inlet seat the weldment. Because the feed pipe may be fitted to the nozzle at so many angles and orientations, it is suitable for a wide variety of job applications.
