hello all, I was wondering what is under most peoples work desks as far a compressors go. I have a 2 gallon Delta Air Compressor, One that you would by at Home Depot. Is this a good Idea to use for an Airbrush? If so what would be a good PSI to paint at? Any help would be great on this one.

Normally spray about 20-30 psi I have a compressor thats for home use as well and find it
impossiable to spray any lower than 20 I've treid diffent airbrushesand liquids and just cant do it so I dont understand how people say they can spray around 10 psi I cant even get water or thinner out less than 20

I set mine at about 25psi. Any higher and you tend to blow paint all over the room any lower and it will not spray the paint out.

I too do not know how other people can spray at the lower pressures.

Hi All
I think those lower spray pressures are being done by using a Gravity Feed type of air brush. This type of system needs much less pressure than a syphon type. Sucking the paint up through the bottle and then out the spray head just takes more air. Where the gravity feed needs no air pressure at all to help get the paint out the nozzle.
I hope this helped!

I use a Badger 480 Silent Compressor and use it between 15 - 40 psi depending on what I'm spraying. I have both a Badger 150 and 200 AB bottom feed and use both at low pressures with no problem.

I guess it's all to do with type. My Badger 175 is a bottom feed and needs 1.5 bar (approx. 22psi) to operate up to standard. My new H&S Evolution gravity feed starts working at 0.5 bar (approx. 10psi), thinner that is. For a good paint result it needs 1 bar (approx. 15psi).

Hi Herchealer
First welcome onboard!
As for me I use the cheepest Sears compressor with the largest air tank I could find. It's 3 hp, with a 15gal. tank. It's kind of loud but it does't have to run long. I own three AB's. Two Badger's, a 155 Anthem, and a model 150, in which I use the fine needle and tip. Then my pride & joy a Tamiya HG-Superfine gravity feed. (I've been told their made by Iwata.)
I think the low spray air pressures spoken about below are achieved using a gravity feed type AB. Air is not needed to pull paint through a syphon system so less air pressure is needed. Thats how mine works.
Happy Modeling!

That compressor should work fine for you.. I have a Campbell/Hausfeld(sp?) 2 gallon compressor that I bought at Walmart and it does a good job...
I use an Aztec airbrush with gravity feed cups and spray between 16-22 psi. with acrylic paints.

I use Badger's Millionaire Silent Air Compressor - and routinely shoot between 15 and 20 psi. This is a good and rugged piece of equipment.
