Scuba Cylinder for Air brushing.

[michael lambert]

Hey peoples,

I used the search for "Scuba" but did not find anything.

I am an avid Scuba Diver and that being said i have my own compressor for scuba and several tanks. I was wondering was there some sort of regulator out there i can hook up to a scuba tank or scuba regulator in order to use a airbrushing kit on it?

I can get up to 4500PSI in my little steel 14cf tanks, it would be plently of air to last me a while i would assume its jsut a matter of a regulator and adapters?

Regards,

I don't see why not, if you can find the correct size regulators/hardware. People use CO2 tanks (welding or beverage) for good clean/dry/quiet air source for airbrushes, so if similar hardware can be found for the scuba gear you should be in business.

You should find a reliable regulator to have 10-20 PSI max, and a moisture trap. Looks a great way to model on holidays? LOL

Actually, IIRC you wouldn't actually need a water trap. The air that is compressed into scuba tanks is dried I believe - otherwise the diver could drown in his own air (at least that's what my scuba diving buddy told me)

I was looking into this solution myself but the cost of the tank and regulator and various fittings made it more expensive than the hobby compressor I bought instead. But for you it could be a really viable solution.

Partially right, Air in scuba tanks are clean and dry. Moist air is bad in scuba rust tanks and causes dangers in cold water diving as the mositure will freeze and cause freeflows in regulator stages.

Well even better.

It turns out we have an extra tank and regulator for welding at the shop. So i will be using it instead having hte compressor and fittings i can fill the tank with compressed air easily.

I use Nitrogen from my local welding gas supplier. It's a stainless steel tank, with a regulator on the end that let's me turn down the flow to a very slight whisper if I want. I would think this would be much the same as what you want to do.

I love it. No noise, no moisture, no hassle. Works great.

Good deal! But if you literally mean air consider using CO2 instead as previously mentioned. It's cheaper to fill than other dry gases and the fittings may be airbrush ready. If they aren't your local welding gas supplier should be able to make an adapter as they did for me. Also, check the fittings to be sure that you don't have reversed-thread connections as they are incompatible with airbrush connections, but this can be fixed with an adapter as well.

Between the adapter and the tank I use a shut-of valve. This allows me to keep my regulator setting and still be able to turn the tank off. As well it serves as a back up should the regulator not be closed properly. It only cost a few dollars more and was cheaper than a refill of the tank.
