For the life of me I cannot get a narrow fan pattern on my spray gun.
I'm running a Graco 390 and a rac x 108 FF tip. I have the pressure down to
1000 psi and also tried cranking it up but still the same circle pattern.
And also the same deal on purple ff tip., 208.
Spraying waterbased enamels.

Two things come to my damaged mind, first when shooting fine finish tips use a Flat Tip and increase the orifice size along with viscosity, there is always a perfect balance in adjusting those two. Second, Flat Tips just give a nicer fan, there should be no need reverse a Tip shooting a finish, hell you are filtering the material twice in the system and should own a strainer bag. Paint like a Painter and get your material ready for spray. Understand the relationship between Mesh and Orifice size and for the Tip and Pressure guides in the specs. keep in mind that those were most likely in a controlled
environment so stir it , strain it then see how it flows off the stick. One last thing...For the price an Air Assisted Airless cant be beat but you still need to do your job. Thanks for Listening RM

Often times a Round Pattern indicates a worn out tip. Remember, small orifices wear out faster......
