Airbrush air source

I lease two 20 pound bottles.  One can get them at any welding supply store, or probably wherever propane/butane is sold.  They do provide a very quiet, moisture-free propellant.  I like CO2.

Much appreciated. I plan to spray out on my balcony of the apartment.

As long as you handle the bottles sensibly during transportation & storage (preferably chained to the wall) & remember that you require decent ventilation CO2 is a pretty good "air" source.

If the bottle will be used / stored in a domestic environment I would advise fitting a CO2 detector just to be on the safe side.

I've never seen a CO2 detector.  Now, I know a lot of hardware stores sell CO detectors, but that is something else.  Where does one find a CO2 detector?

Don - they are more of an industrial type thing gas, HVAC, lab & the likes & not readily available like CO detectors. Needless to say as they aren't a consumer product they are more expensive......

It may seem like overkill, but I've read far too many posts over the web of users losing the contents of a CO2 bottle due to poorly shut of valves of leaking equipment - a large bottle leaking overnight in a small, single storey building with poor ventilation & the bottle located near a bedroom could be very nasty I imagine?

Yeah, when I was in the Air Force we lost a couple of guys at the bottom of a missile silo with a leaking CO2 cylinder.  I guess for any kind of painting, having a shop with good natural ventilation is key.

I was wondering if I could use scuba tanks for an air supply....

Make sure you use a moisture trap on ANY compressed air!  That bottle will chill as it releases, so the gas you get out will be colder... and condense moisture in the line.  Watch your paint carefully.

I got a compressor made by California Air. It's really quiet.
