    Most of the small tankless compressors get HOT. even the ones with tanks get hot and are not really designed to be used long periods of time constantly. They do have a thermal protection that shut the compressor off if it gets too hot ( or at least most do) . Overheating can cause perm damage However the damage would not likly cause the moisture build up you are getting. You could try getting a small fan to blow across the compressor while in use. Unfortunatly these compressor are not meant for long uses. having a tank ( even a small one ) would greatly reduce wear and tear and heat build up

  5. Its a no oil compressor.

    I'm just more curious as to why this happened out of nowhere.

    I watched this video on YouTube. The guy took off the top cap of his compressor and exposed what i would call a small metal sleeve. He said this sleeve or tab, needs to sit flush on its surface.

    The tab on mine was slightly convexed. I flipped it around and now its completely flush.

    Maybe this will change things ? I haven't turned it on yet because honestly I'm so frustrated i cant take more failure.

    I'm a commission painter and need to get this work done. Its just so frustrating

    I honestly do not know anything about the internal working of the air compressor. So I can not give any input as to if that will help your issue. I do however know alot about frustration. Just take a breath, take a break, and give it another try.

    I was thinking if he is using that compressor for getting money, why not getting better&bigger compressor. I know money can be a problem I'm not stupid, but... I would still like to hear how much the one he uses costed.

    I know on amazon those compressor are from 45-90 usd. I use the same type of compressor but I do have a small tank on mine Ive had it for about a year and use it 3-4 hrs a day. I have overheated it to where it shut down. but other than that I have never had an issue. I do know that I will need to replace it soon as they do not normally last long with constant use

  10. Honestly, i bought it off a friend. He used it about 3-4 times, which is why i purchased it. It worked fine 100% so i was happy.

    But on amazon they range from 60-100 like crazyvet stated.

    I think i may just buy a bigger/better compressor though, it will probably help in the long run.

    However, i dont like running from problems. What if i have this problem again someday? I like to find the cause of issues and know how to fix/trpubleshoot them.

    You guys have been great tho. Very friendly and I appreciate that !

    I destroyed one compressor in 1 year I think. But if I would be under the pressure of time limit when those miniatures needed to be done I think I would like to have something which will not hold me down. I am just thinking out loud! lol

    on other hand I hate jobs where I am under time pressure. I get to much stress. I worry to much. :)

    I just remembered. Few weeks ago I was shown compressor without air tank, one of those cute small ones and store owner sad you don't get any pulsation while using it. He hooked up micron on it and show me. That little compressor started to work as soon he pushed that trigger down and shut it down automatically as soon he let trigger go. I didn't see any pulsation where paint was sprayed, but maybe I am just not experienced enough. I wonder....

    when I noticed my compressor would go to hell I started to saving money for new one. It was very pain full experience to pay for my compressor, costed me if I remember 630 euros. My heart was almost broken when I was handing that money. lol but I don't have frustrations any more so I did a favor to myself on a long run.

    It all depends of the situation in which each person is. I am sure you will figure it out what is best route for you on a long run. I was just wondering, cause you are painting for money, why should compressor be the thing which holds you back.

    Chuck already gave you the information you need above. I'll reiterate... Those small, air cooled compressors are designed to push out only enough air to run the airbrush. That's it. That's all you get. The issue is, the compressor must run constantly to continue pushing out that very low amount of air. That causes heat and a lot of it. The heat creates moisture through condensation in the tank that eventually works its way into the airline. You don't have a tank which means the moisture travels directly into your airline. If this problem suddenly started occurring for you, there's a better than average chance something has worn (probably piston rings) internally in your compressor and it's creating more heat while it runs now than before.

    Those small compressors are cheap and marketed toward the hobbyist for that reason. The truth is, they are all about the same regardless of brand (I learned all of this the hard way years ago too). None of them are designed to run an airbrush for more than a few minutes without allowing it to sit and cool off. Those that come with a tank aren't any better. The compressor doesn't put out enough cubic feet per minute of air to refill the tank and shut off. It will still run almost constantly. When those small compressors are used the way we airbrush artists use them, they wear out fast and/or break. A compressor is one of those items that falls into the category of you get what you pay for. There are good options out there for a reasonable price that will last you a very long time though.

    Something not too big, but not a junker?

    I think people here will ask you how much money you would like to invest in a compressor. Just guessing.

    It also looks that you’ve received advice from some knowledgeable folks :)

    All compressors have a ‘Duty cycle’ which is how long it can run before it needs to be allowed to cool off. The smaller they are the shorter this time will be. So for example you may be running the compressor for 10 min but need 15 minutes for it to cool down, I’ll do some checking and see if I can find out what the average is for the small tankless ones.

    As the others have said, a small ‘pistol grip’ style filter at the airbrush may be helpful, and yes, the moisture will be created in the airline... the air is hot in the compressor and as soon as it cools down in the hose it creates moisture. The moisture trap at the compressor will collect excess moisture from the tank but won’t help for stuff created in the hose

    I don’t know the answer but I get spitting every now and then, which is why I would always have the regulator trap and also a quality moisture trap at the brush too,

    Its simply a hot compressor, the moisture trap cannot work because the air is not cooling before it gets to the moisture trap. Those tankless compressors have to work hard. And if in a high humidity area, combined with an overheating compressor its the perfect storm. If you add a moisture trap after a few feet of hose it will be able to catch and collect it there. As a fact, i have a coiled hose from my compressor to another moisture trap and regulator then a multiple valve block to my airbrush hoses. Humidity here is very high. You can try to cool the compressor, or you can add a tank after the compressor which will allow it to shut off and on instead of running the entire time you paint. And I highly recomend the tank addition.
