CO2 as a propellant

Yes, I've been using CO2 for close to 20 years.  It works great, clean, dry and quiet. Don't need filters or water traps at all.  Just make sure that you get a regulator for CO2 that can drop the 800+psi tank pressure to someting your airbrush can use (5-40 psi).

Thank you.  I have tank mount Primary regulator sets for both 0-30PSI and 0-60PSI.  I will probably just use the 0-60PSI set for most applications (gauges are only really accurate in the middle third of their scale, eg. a 0-90 PSI gauge is most accurate between 30-60 PSI).  I am just getting back into this after a 30 year hiatus due to my Son.  CO2 is my best (personal) option without going out the garage and using the compressor designed for air tools (WAY too big).   

Cheers!

There have been a number of threads on this in recent months, with good details on threads, regulators, etc.  Look over the older messages for maybe the past year.
