compressor moisture problem

[maxxpaane]

I just bought a mini comp from tcp global. It has a moisture trap and my ab has one also. When I was ab today I had water spitting out all over the place! I checked my little trap on the ab and it was full. My other 2 gal comp never did this. Any thoughts?

a compressor without a tank ran constantly will eventually spit water even with moisture traps because it gets hot, and hot air creates moisture. I had an Iwata smart jet for a few years and would airbrush for 8-12 hours straight and would get water even with all the traps & tricks (except an air dryer). I've been using an Iwata Power Jet Pro and have not had a water problem yet, and it's from having that little air tank on it to cool the air just enough.

Try putting a fan full blast right on your compressor to keep it cool, get a bunch of coil hoses and hook them together to help cool the air, I've also tried keeping my hoses dunked in cold water.

Yip, had a few mini comps with no tanks...None would go more than an hour or so without shootin water all over...No matter how many Traps I had....About all you can do is like what JP mentioned......I got sick of chasing the problem...Go me a 60 gallon comp with a huge water trap..hahahaha!..No worries now:D

J.P. and ABD your both right. I did notice the little booger was running pretty warm and constant. I think it's just under a gal. I bought this comp so I could ab downstairs, because everytime my 2 gal would kick on it made me jump!

haha..My 60 gallon will damn near make yer heart stop if yer not used to it....Can't talk anywhere near it either, have to scream for anyone to hear ya...hahaha....I'll sacrifice noise for no water probs any day tho..LOL

Yeah, I might switch and give my son(he's 9) the little one since I'm trying to start him learning young. I just bought him a Master ab to start with. I figure since I'm still learning who knows he'll probably be able to teach me a few things.

Funny....I still have the same tankless comp as when I started & it spits water rarely (happened 2 times in a year)...Just make sure ya put it on FULL & have a mac-valve. That cuts the time that ya comp runz in half. A double hose & an extra watertrap in beween helps too.... The plus point is ya can ab while everybody is aslepe....it makes less noise than a fridge..

Funny though...I read all these threads about moisture problems, why doesn't it happen to me?? hehe

[maxxpaane]

You better knock on wood Crazyman. I'm done with it!!! Even though I'm still green to this, I don't need a bunch of water spittin out and making my stuff lookin any crappier than it is. Goin back to the 2 gal comp.

Smaller compressors have that problem more so than large units, but keep in mind the area you live and the weather conditions......both of those have an effect on the amount of moisture you get......I live in SW Arkansas and have to deal with very high humidity most of the time so i'm constantly checkin my traps, and i've got a 60 gal tank......so if you live in a humid climate you'll most likely have the same issues.

Right now its after midnite and the temp is 75 degrees but the humidity is 75% which makes it feel alot hotter than it really is......High humidy has caused me all kinds of problems with clearcoats so I really have to watch that and only shoot clear when the humidity drops since I don't have a high dollar climate controlled paint booth.

Yeah, I don't know if using it in the basement with the a/c on would have any effect on it. Does seem there would probably be more moisture in the air.

Bigger traps and longer hoses help......Those mini traps that come with the lil comps are damn near useless IMO.

I don't know where your trap is..In my case..I have my comp, then about 25' of hose to the Trap......The longer hose helps the air cool before it gets to the trap..........Same thing with lil comps.....Like JP mentioned the coiled hoses work good for this....Leave it coiled up (all compact like), Air still has to go threw 25' of hose even if it only takes up 2' of space...

[maxxpaane]

That might be the solution. My 2 gal has the recoil hose plus the ab hose. My mini comp has a trap at the front then a 6 ft hose and a trap on the ab. I probably need a longer hose, just like you guys said-thanks.

as a quick fix and cheap desicant fill your watertrap bowl one third full of childrens disposable nappy material ,i believe its silica gel based and it absorbes lots of water

or use those tiny packets of silica gel that come in lots of comercial packaging

ac dries the air

LOL my 30 gallon will do the same thing i have a few funny lines on my work from jumping out of my skin lately i can fill it once and can brush for about 2 hours before it run's low on air

the guys at coast told me to run a hose straight up for 6 to 8 feet and it will help with the heat/ water problem

I did some work at a bodyshop once that had these filters that you put a roll of toilet paper in every week.....worked great!
