A spray nozzle, particularly well adapted for use in compressor spray cleaning systems, has a nozzle body with a right angle fluid delivery bore having a first passageway section extending longitudinally and at least one connected transverse nozzle bore section terminating in a reduced diameter spray bore at a sidewall of the nozzle body. A swirler is mounted in the nozzle bore section, and has a head section with a plurality of passageways formed between swirl vanes arranged about a periphery of the head section to pass fluid to the spray bore and an adjacent neck section of a reduced diameter. The neck forms an annulus between the neck and the nozzle body in fluid-passing contact with the first passageway section and head section to direct fluid from the first passageway through the head passageway for exit through the spray bore. The nozzle can be used in spray systems over a wide range of fluid delivery volumes and pressures.
