Help with LVLP gun setup

[Paint munky]

Ive be spraying for a while now with HVLP mini gun and starting to get some pretty good results, i only spray bike panels and wheels so working with a mini sized gun hasnt been too much trouble although i recently decided to get a proper sized gun for some of the bigger panels i do. I opted for a LVLP gun as i understand they dont need a massive compressor to work but whenever i use the gun it seems to splutter therefore i dont get a good finish and i always end up tipping the paint into the mini gun and using that.

Can anyone advise me on what im doing wrong and how to set these guns up, the guns i have are as follows.

My compressor is a Fiac 2HP 100L which i belive puts out around 9CFM

the second lvlp at 8.2 cfm doesnt sound very low to me
if it is spluttering then there could be an issue with the gun try tightening the gland nut near the trigger but not enough to make the needle stick also check the paint nozzle for any cracks and make sure the gun is clean.

if it only happens so far into spraying could it be your compressor is running out of air your compressor at 9cfm is very borderline for that gun as the gun is 8.2 what is the FAD of your compressor it could be too small for that gun

just had a look if your comp is the ccs 100-245 then its an 8.8 cfm

Thanks will check over the gun tomorrow. Im not sure what the FAD is, will it be marked on the compressor somewhere?

Its not like the comp is running out as it happens as soon as you start using it, although saying that i have noticed the comp is taking longer to get up to presure lately.

i doubt it will be marked and fiac dont give the info either you can take a look here

sounds like a gun issue just strip the gun clean it & make sure there is no old paint anywhere and rebuild it, if it still splutters take it back and ask for a new one

My comp isnt as new as those ones lol, mines one of the old blue ones. Will check over the gun tomorrow, thanks for the pointers

You were bang on snooper, the gland nut must have been just a tiny bit too loose. It works luvely now, it should have been something i spotted myself to be fair but i am new to these things

i was thinking of the very same lvlp gun myself, what's it like? it got a really good review in bodyshop magazine.

Well upto until yesterday i would have said it was ***** but as you can see i was having issues with it, I did a test panel yesterday and it came out spot on, well to the best of my abilities anyway. Its light and easy to handle and im sure it will give just as good if not better results as the deltalyo mini gun ive been using for the past year.

I started off spraying with cheapo guns people gave me or i brought off ebay and the budget stuff they sell in paint shops, i never really had good results but id say most of that was down to my abilities than the guns but once id splashed out on the mini detalyo my painting improved ten fold, now ive got round the issues of this LVLP gun i fully expect the results to be just as good.

The devilbiss range is a little too pricey for me and the detalyo guns were a little cheaper but i think the quality is very good, it comes in a nice box with 1.3 and 1.6 setups, a reg, conectors and cleaning brushes. Well made too.
