Model Forum / General / Rockets / December 2006air compressor recommendation
I need help choosing an airbrush compressor... I will run a Paasche VL type airbrush on it and will spray things like guitar bodies to T shirts or whatever art I might feel like doing. However I am a little confused, is it better to get a bigger HP compressor (therefore cfm) or it doesn't matter, just get a 1.5 hp with a 6 to 8 liter tank? I would think that big tanks wouldnt matter if the pumps cant keep up anyways. I dont forsee using impact wrenches or whatever but I might use a smaller detail spray gun later on (and even that is doubtful) I would assume that an airbrush doesnt use that much air anyways?  SignatureTAI FU Badger, Badger, Badger. Don't waste money on the bulky, tank-type compressors you find in discount, auto parts or hardware stores. They're noisy, trashy quality and will likely only last you a year or two, and by time you add the necessary adapters you'll spend just as much anyway. > I need help choosing an airbrush compressor...

Correct. Back before you were born, I got an airbrush compressor at the local hobby shop. It's about football sized, made by W R Brown in Chicago. Don't know if they are still around. It was about $40 when I bought it, but last I saw, these things run well over $100. It looks like this one that just sold for a bargain on ebay: http://cgi.ebay.com/Paasche-Type-H-Airbrush-Compressor-Hose-Accessories_W0QQitem Z140067217007QQihZ004QQcategoryZ134557QQcmdZViewItem If I were in the market today, I'd look at a decent automotive type compressor, with a long hose. The smallest one is more than adequate to run any airbrush. Yes, the big compressors are noisy. But so are the little ones, especially if all you have is a 3-6' hose. Plus the little compressor runs 100% because it has no tank. The big ones can at least cycle on and off as needed, which won't be much for an airbrush. The best fix for noise is distance and a long line. With the big tank you can also use it for other things, from inflating bicycle and auto tires, "sweeping" out the garage, to running real air tools. I'd avoid the off bransd stuff you've never seen before. I've seen a small one at Sears regularly on sale for $100 or so.

I have seen a lot of compressors that is 1.5 hp and its very similar to the ones you see in Harbor Freight (its most likely made by the same guy too) or other discount tool depots. They dont cost too much but I gotta add a regulator and moisture trap to it because its not included. Figuring to spend 200 dollars total for the whole system including a Paasche VL. SignatureTAI FU There's advantages to both types of compressors. I ran my airbrush with a medium sized pancake compressor for a few years. The nice thing was that I could also use the compressor for small tools like nail guns. However, the disadvantage is that any type of compressor with a tank needs to be purged of moisture every time it is used. Not a super big deal, but it was a hassle any time I wanted to spray something for just a few minutes. It took longer to drag the darn thing out of my garage and purge it when done, than it did for the spraying itself. Not only that, but a tanked compressor is also heavier. Last year I bought a small hobby type compressor and have been very pleased with it. It's a Badger model that doesn't even need a regulator. Just turn it on and it works- rather quietly too. And there's virtually no maintenance and it's easy to pick up and move to wherever it's needed. When done using it, just turn it off. Yea but one of the things I plan to use it for is spraying T shirts or somewhat thick auto touchup paints which will require more PSI than a small compressor can offer... Maybe a solution is get those pancakes or whatever and run a line to wherever you plan on working, and just purge the thing when done... I heard they got those "silentaire" compressor that can put out alot more PSI than an airbrush compressor, and suitable for T shirts, problem is they cost 700 to 800 dollars (which is enough to buy a large shop compressor) but the obvious advantage is that they are very silent.

If you are going to spray automotive paint then you are in an entirely different category of compressor to begin with. The small compressors have no problems with high psi ratings- it's the volume that you would be looking for. Even my pancake compressor with a tank can't support a high enough airflow (cfm) to support an automotive type paint gun. A large compressor that you would need would still certainly work for an airbrush. But you'll probably eventually have a desire for a small hobby type compressor that's so much more convenient to use. I never wanted to spend the money on one myself and finally crossed the threshold when our local Michaels craft store had a 50% off coupon. > Yea but one of the things I plan to use it for is spraying T shirts or > somewhat thick auto touchup paints which will require more PSI than a small [quoted text clipped - 4 lines] > problem is they cost 700 to 800 dollars (which is enough to buy a large shop > compressor) but the obvious advantage is that they are very silent. Tai - You might consider a divers tank instead! I have a very nifty compressor purpose built for the air brush but the trouble with compressors is they warm up up the air considerably in a very short time which then condensces water out in the air line, eventualy spattering out the air brush to ruin your work. You can reduce the problem by pumping to a reservoir tank and using water traps but yopu will still get spatters from time to time. I recently bought a new divers tank for my pre-charge air rifle. It was cheaper than the compressor, costs me 3 UK pounds to get filled, can push out a clean stream of air at a range of pressures and doesn't need a power supply! You can even pick them up relatively easily second hand (particularly among the air rifle fraternity) Wish I'd known about it the first time round...

Yea but the problem is that scuba tanks are useless for air tools or dusting off the place every now and then...

I dont forsee using impact Tai just get an air tank, like the 5 gallon types. can be filled at any gas station, and will provide hours of airbrush time. you will have to get adapters, regulators, driers, and other such things, but you need to get those regardless of the replies made here. or if you want to get real cheap. use a spare car tire. Yes but the problem is that gas stations in Taiwan don't provide air fills for free... you gotta pay for it. Plus a 5 gallon air tank isn't that much cheaper (like 10 dollars cheaper) compared to a 1.5 HP 1.5 gallon compressor... SignatureTAI FU > >> I need help choosing an airbrush compressor...
