Would airbrush propellent work wit GBB???

[pvted]

Hey guys, i'ts been awhile since I posted here. I kinda got out of the sport for about a year but now im back in.

Now I was at wal mart (lol) looking for airbrush propellent for my airbrush. Then on the drive home I was thinking "hey this stuff is kinda simular to duster gas", like both make air lol :lol: . I did a search here and nothing came out, only the "letra jet?"(I think thats wut it's called) stuff was mentioned.

Lets say we can stick the AI duster adapter on to it, then my friends we might have a new gas to put in our GBB's . The airbrush propellent I was looking at is the Testors Airbrush propellent it's pretty damn big can, it's around $11.00.

Thanks for your time and suggestions if you give any.

if you read the AI site it says he tried out various airbrush propellants and since he doesnt have an adapter for it i doubt it would work very well

Thanks for your reply

Im lookin at the AI site right now I can't find where it says that or the specific article. Would you happen to have the link???

LetraJet is an airbrush propellant I used to use before I discovered the contents of green gas cans. It required a significantly different adaptor design than my current design owing to it's different valve fittings.

LetraJet was actually HCFC-22 and has been discontinued because of it's ozone depleting properties. Aerosol use of HCFC-22 (READ HCFC, not HFC) have been federally phased out in 2000 so I caught the tail end of LetraJet sales just as I got into airsoft (I've played 7 years?!).

If you have a can of HFC-134a (tetrafluoroethane), you've got a can of lower pressure propellant (lower than propane), but higher pressure than HFC-152a (difluoroethane) which is becoming prevalent because of increased usage of HFC-134a in the refrigerant industry. There has not been a significant increase in 134a production, but there has been a significant increase in 134a use in refrigerant which is why we see bottlers switching to 152a which is not as good a refrigerant.

Honestly if it was a HFC-134a mixture I would have bought a trunk full of testors airbrush propellant. But even im not sure of whats inside the can, it just says ozone safe (prob not HFC-134a then) and a long long list of first aid advice. I would have used propane, but im more of a indoor person, so the smell of propane in the basement is kinda lets say dangerous lol cause theirs a furnace, I don't want a explosion to go off.

[MadMax]

HFC134a is not ozone depleting. Look carefully, USDOT requires disposable cans state their contents. You should be able to see what's in your propellant.

Thanks For your reply

I honestly didn't know HFC134a issnt a ozone depleter, the fools at kuramae told me that, now im a fool for listening to them. As for the can well either im blind or the contents just arn't listed . I snapped a few pic for you guys to see. You should be able to make out the lettering after all I hope didn't waste over $500 smackers on a 10.1 megapixel cam. Tell me if the pictures can't be seen or if the links don't work .

It's not a big deal once you actually get out to an indoor field, those facilities are usually many thousand sq ft so the gas dissipates rapidly..

By basement I mean my tiny closet sized basement (exaggeration lol ). I just line up some targets down there, a GBB is just to keep me from dying of bordom on weekends. In fact the term for me is chairsofter lol. Sorry if my post had any confusion. So yea im definetly concerned about using propane in my basement, it could ignite my backside lol and it smells, I almost die when lighting up the BBQ. If those factors are gone I would have definitly have gone for propane, cheap n powerful.

[MadMax]

Your second pic states the contents pretty clearly.

Propane and isobutane blend. I'm guessing a 50psi ish blend similar to what's in MSR camp stove fuel.

[pvted]

Thanks for your reply

lol I definetly need to get my eyes checked, im an idiot lol . Definetly my bad I should have looked closer than waste every bodies time .

Well now that we know it's some sort of propane blend, it seems like it might work eh ? Now the only problems are: would it cycle the GBB, would it fill the mag and would there be enough power to fire it with out destroying a GBB. These are more of try at your own risk scenarios then hard evidence. Im not even sure the AI duster adapter will fit but it looks promising. If it does work, boy would it help people who don't like actual propane or the cost of green gas.

[MadMax]

Nope. It will suck. Straight propane exerts around 120psi at room temp. Most propane-butane blends I've come across exert only 50psi which is even less than hfc134a at 70psi.

[dodger_me]

what about just strait air? refill your mags with one of those small containers then refill your container with an aircompressor. it would be cheap for people that dont mind topping up a tank every game day

[gunscythe]

Straight air wouldn't work, as there would be no liquid. You could get it up to 120psi, but then the pressure would drop dramatically after each shot. You need the liquid in there to "resupply" the gas/pressure.

[pvted]

Thanks for your replies guys

Well I guess madmax amd gunscythe's posts basically summed it up. No new air source for us . It's a real dissapointment, I was about to put money on it that it will work. But looking at the airbrush propellent it self might not have been great cause I loose pressure on my airbrush after 30minutes? unless I put it in a tray of water. Still I want an air source that won't actually start and explosion in my basement, you guys know where duster cans can be bought in bulk for cheap (I live in Hamilton)??? Now im not talking about just a 3 pack im talking enough to last me awhile, so I don't have to drive up and down from the flippin store.
