Nozzle Sizing and Calibration Charts

Need to find the right nozzle size for your application?  Sometimes a simple chart is the easiest way to figure things out.  Print it and place it in your sprayer cab.

In this chart, identify your water volume along the top row, and follow the column until you encounter the travel speeds you’re interested in.

Once you’ve encountered your travel speed, move along the row to the left to identify the nozzle size and spray pressure.

Make sure that your travel speeds are achieved at a pressure that’s right for the nozzle you’re using. For most air-induced nozzles, this will be about 60 to 70 psi (highlighted).

Once you’ve decided on a nozzle size, the travel speed column for that size becomes the travel speed range at various pressures. Avoid operating a low-drift spray below 30 psi – its pattern will be too narrow and likely its spray quality will be too coarse for good results.
