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 5–20 psi
(0.035–0.14 MPa, 0.35–1.4 bar).
•
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.
