Help Please.UV clear with a Sata 3000 RP 1.4 tip. I have done a few jobs using very slow activator when it was a 100 degrees and 895 reducer with good results.. I shot some yesterday using normal and got not orange peel but grape fruit. I reduced with 870 around 2 ounces to a mixed quart and it did better. SATA Says use a 1.3 wide open at 29 psi for HS clear. What fluid tip do you sata guys use.Also what reduction do you use when flow coating.THANKS!
 
I would bump your air pressure up a few pounds 32-35psi. Also maybe turn in fluid a turn or so and see if that helps. I don't normally reduce universal but if working for you good but don't over do it. Joe
 
That gun normally sprays the universal really good.
A few things to check.

Make sure the internal gun strainer is not in the gun.
Fan should be 90% wide open.
Fluid 2-2.5 turns out.
MOST important!!!!!!! with that gun, regulator at wall needs to be 130-150lbs, gun will not spray at 80-100lbs.
Also that gun sprays best at 6" from surface.
Also like said 32-35 lbs with trigger pulled at the gun.

Barry, a few questions...
If using the digital sata, should the regulator at the wall still be that high? The reason ask is because I use the air control on the gun to control the air pressure at the TIP and not a regulator at the gun.

I saw a video on youtube from sata that when using the digital gun, if the pressure coming into the gun is too high than the control knob is really shut. So the actual opening inside the gun is like a pin hole so the flow volume is reduced. And if the pressure coming into the gun is, say around 40, then the opening inside the gun is larger, allowing more volume(same psi). What is your (or anyones) opinion on this? I currently have a sata hvlp 3000 1.3 digital and thinking of getting a 4000 rp 1.4 digital.
 
This isn't really an answer to the question, but to make things more clear about air adjustment at the gun, even a digital SATA is reading air inlet pressure, and nothing to do with the tip or cap, which is measured with a special air cap gauge. 10 PSI at the cap (standard for HVLP) might be 30 at the inlet, each gun is different.
 
Those Sata's really respond to high flow air fittings, even the older ones like the Sata jet 90, they like air! Use a decent diaphram reg at the gun instead of the internal if it can't handle the pressure and feed the gun all the air you can.
