: Tip Selection and Application Speed Guide 103
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 NCVs 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.
NOTE: Refer to the tip manufacturer for latest information.
Refer to this key while using the example spray tip droplet size table:
