Is dark-green gas propane or is information technology like propane?

Light-green gas is not similar propane. It is propane. Green gas is non R22, or Co2, or "CH2FCF3CH3" (as seen on some bottles). It is merely run-of-the-mill propane, with a different scent added.

So it'due south actually propane? How can you be sure?

Samples were sent to the Analest Laboratory at the University of Toronto where 3 brands of greenish gas (Jet, Green Power, Shooting Air) were analyzed with a gas chromatograph/mass spectrometer, an industry standard for organic gas assaying. All three gases were shown to be propane. Additionally iii more than brands have shown to be similarly combustible and exert the same pressure. Test results, word and conclusions tin can be found in the Lab Data section, please read the Laboratory Analysis of Light-green Gas for more in-depth information.

So, why should I fill up my gun with propane instead of greenish gas?

If yous use green gas, you're already using propane. Domestic propane is cheaper, comes in a safe container, and is bachelor at any local hardware store. Airsoft bottled propane (green gas) has to be imported (which can accept a long time).

Isn't it flammable?

Dark-green gas has ever been flammable. At present that we know it's propane, nada has changed. You should never ignite propane/green gas, or release information technology near an open flame. Nevertheless, propane is adequately safe for normal use - nosotros already apply butane (another flammable gas) in many consumer products, such equally shaving cream and hairspray, and propane is used as an industrial refridgerant (it'southward also known as HC290).

How come green gas smells different than fuel propane?

Fuel propane is scented with mercaptan odourants for leak detection. By itself, propane has very little smell. Different bottlers of fuel propane use unlike odourants and so do greenish gas bottlers hence the different smells. Green gas and fuel propane are primarily propane so they all perform similarly in the stop.

Some brands of green gas are lubricated. Is propane?

Propane is not lubricated. Nevertheless, the blueprint of the AI Gungas propane adaptor makes it easy to mix silicone oil into your magazine fill accuse, and includes an instructional video detailing exactly how to practice it. Airsoft Innovations also carries ultra-lightweight silicone oil platonic for GBB maintenance.

What about my slide breaking, or seals being damaged?

Green gas is propane, we've been using information technology all the time, there is no difference. Add together a few drops of silicone oil, as shown in the AI Propane Adaptor instruction manual, and your gun will exist only too off as with "light-green gas". You shouldn't utilise propane/green gas in any gun that is not designed for higher pressures (e.grand. un-upgraded Western Arms GBB'south). Some GBBs are designed expressly for the utilise of HFC134a (a lower pressure gas). Propane is not a expert substitute for HFC134a in GBBs designed for HFC134a.

Volition my gun perform the same on green gas and propane?

I have some chrony results comparing propane from a Coleman stove tank and a brand of gas chosen "Shooting Air". Tests were conducted with a SVI iii.nine" with metal slide shooting 0.25g bulletin board system. Shots were washed with a completely filled mag allowed to warm up to room temperature for 30min. Shots were fired every 5 seconds to reduce cooldown.

Propane (fps) 289 285 283 275 273
Shooting Air (fps) 281 282 281 277 280

Volition propane damage my gun?

GBBs modified to handle green gas (nosotros really have to cease saying green gas) are already propane ready. Sure GBBs in stock course (WA, TM to proper name a few) are not propane ready. The higher pressure level of propane tin overstress a stock plastic slide and crusade it fissure or completely break. Still, many users burn down them on propane as they consider the performace/durability tradeoff acceptable.

Are propane tanks safe to comport in the field?

Yes. Most disposable propane fuel containers feature overpressure relief valves which allow propane to leak out before a can is over-pressurized and explodes. They are too of heavy steel construction which withstands very high pressure level. Conversely, light-green gas bottles are thin walled aluminum without overpressure protection. In a few cases, these containers have exploded with frightening result. One time, shrapnel from an exploded greenish gas tin can perforated a vehicle roof.

How come nosotros've been using propane, and nobody knew?

The suspicion has floated around for a few years, but until at present, no one got around to actually testing the stuff in a lab. Green gas has always been mislabelled, with fake chemical formulas and incorrect pressure specifications – nobody questioned them.

Can I see your examination results?

Absolutely. I've compiled all my testing information, results and conclusions in the Lab Data section, please read the Laboratory Analysis of Green Gas for more in-depth information.
