Spray nozzle selection is driven primarily by application and intended outcome.
Spray nozzles are characterized by spray pattern, flow rate, atomization, and spray angle. Each of the factors outlined in this section will have some bearing on selecting the right part for your application. The specifications and guidelines cited are tested using water (or air for air nozzles), and under ideal conditions. See Factors Affecting Spray to understand how different applications and circumstances may affect part performance.
