An external mix air assisted spray nozzle assembly having a nozzle body with pressurized liquid and air passages, an air cap having a central opening in coaxial relation to a liquid discharge orifice of the nozzle body for discharging an annular air stream in surrounding relation to liquid discharging from the discharge orifice, and the air cap has a pair of opposed thin walled cylindrical members projecting in opposed relation to each other for directing pressurized air to atomize and shape the discharging liquid spray pattern, while minimizing undesirable build up of solids on the terminal ends of the projecting cylindrical members.
