Gun Question

[4point0]

I just got a Sata Jet 3000 HVLP and I cannot get this thing dialed in! I have stripped down the entire gun (even though it's brand new) and checked and double checked that all the pieces are perfect. I have tried to adjust everything to the way I like it... But I just can't get this thing to be consistent and even. What do you guys usually have your Sata's set at?... What do you have your compressors set at?

All my others guns work great and I tried to mirror their settings for my Sata... but no luck. I need to get all the bugs out of this gun because I have to paint a friends bike in a couple weeks.

Don't know what the problem could be. I"ve never seen a new gun that can't spray decent, even the cheaper ones. What type problem you having? Fan not big enough. No fluid getting through the gun? Pattern heave on top or bottom?

I normally just leave the fluid and the fan nozzles almost wide open and control the fluid through the trigger.

This problem has me confused. The gun just seems starved for air and the paint seems like it isn't being atomized at all. I could use a wagner house painter and it would atomize better. Haha. I've double checked my mix and the paint was perfect... I also added a little bit more reducer just to see if it would lay out a little better. The paint still came out of the gun as if it was too thick. The fan is perfectly even and continued to be correct according to adjustment with the knob. The only thing I could think of that would mess with my paint a bit is temperature. I was spraying at about 60-65 degrees, but had the right product for the environment. I can't figure this out.

What size compressor and airlines are you running? are you getting enough air to the gun?
The specs say 15.2 cfm and inlet pressure of 29psi

Possibly the air regulator is defective. Not for sure how you have it setup, but maybe you can try another setup. If you have a regulator on the end, take that off, and just put a fitting on it.
Or, just another thought...If I remember right, a 3000 already has a built in regulator, so if you have 2 of them on there (the one built in and the one on the end of the gun), this could be the problem.

That's a lot of air. With a 3/8 hose and typical filter / dryer stuff inline you'll probably need 90 - 100 psi at the tank. Install a pressure gage AT THE GUN INLET and see what you're getting with the trigger pulled.

I am using a 3/8 hose and I have my compressor at 80psi. I am going to try to take off the regulator that I have on the gun and see what happens. I am beginning to think that it's not working correctly because the needle tells me one thing and the lcd on the gun will tell me another. I think I might have to crank my compressor up a little bit too.

That's your problem, the Sata 3000 digital has a built in regulator and does not need a reg attached. If you remove the reg you should be sweet.

Turn the knob I have circled straight up and down. Then turn your regulator that you attached to the gun all the way open. See if this will give you more pressure

4point0,
Did you ever get your gun problem figured out?
Like to know what the problem was if you did get it figured out.

:bigokay:

First of all, I don't think the regulator I had on the gun could flow as much as I needed. So I just took it off. It seems to have solved my problem. But I am still kinda confused because I have the same regulator on 2 of my other guns and they work perfectly fine.

 

[nzgrip]

That's because that gun has a regulator built into it. So you're reducing the pressure at the external reg and then reducing it again at the internal reg, resulting in too low a pressure at the air cap. What are your other guns, SATA are the only ones i've seen with a built in reg.

Yep, nzgrip is dead on.
