Delavan says its line of AJ 150 nozzles delivers high-impact compressed air in a flat pattern at noise levels below the OSHA standard. When mounted side by side, the nozzles create an air curtain. Configured for connection to 1⁄4-in. pipe threads, the nozzles' 16-orifice design provides a uniform distribution of air and a good spray pattern across a range of applications such as cooling, warming, drying, cleaning and moving of components.
