Selection Charts
Conventional Guns
An airspray gun has excellent atomization and high production rates typically with some reduction in transfer efficiency.
Proper Needle/Nozzle Selection
The spray gun's needle/nozzle kits range in size to provide different fluid flow rates. As a general guideline, use the fluid nozzle that will give the required flow with the needle fully trig- gered at a fluid pressure of
•For low flow rates or light viscosity fluid, select the smaller nozzle sizes.
•For high flow rates or high viscosity fluid, select the larger nozzle sizes.
•For abrasive fluids, the high wear gun mod- els are recommended.
