TIP SELECTION AND APPLICATION SPEED GUIDE
DRIFT CONTROL AND DROPLET SIZING
The table below shows the drift control specifications for different nozzle manufacturers. Use this information
when selecting the appropriate nozzles for your application.
To properly size spray tip and type, determine the typical spray speed, target pressure for desired for droplet size,
and target rate for application.
FOR EXAMPLE: If the desired target rate is 10 GPA at 15 mph with a medium desired droplet size:
• For conventional spraying, the tip chart recommends using an 05 spray tip at 40 PSI.
• For pulsing nozzles with a target of 70% +/- 10% duty cycle, use a 06 or 08 tip. At 40 PSI either tip
would create the desired droplet size.
