Air supply Q.

Unread postAuthor: RCwiley » Mon Jan 04, 2010 4:36 pm

I am some what new to pneumatic cannons. I am going to build an Inline Vortex bbmg for airsoft but the only thing is im not totally sure on how to power it off of Co2. So I was wondering how i could use a 20oz paintball Co2 can to power it cost effectively. I would need a regulator so i could see how much psi is being put out and be able to adjust it.

Well a cheap regulator is at least 80 bucks plus the co2 will be over 100. You defianatly need a regulator.

Not only that..the CO2 itself is more expensive than HPA.

HPA is said to give less cooling problems than CO2 when rapidly expanding and ofcourse it will give better muzzle velocities.
The last wouldn't be very important for airsoft though...ouch!


On a sidenote...I never realised the muzzle velocity is always close to 0..
It would be better to call it ...projectile peak velocity...or something... :roll:

check craig's list, too.

You could also use propane with a normal regulator. The problem is fumes, relatively low pressure, and a rapid decrease in temperature, thus pressure.

My setup came to around 100 dollars. I used http://corporate.marketplaceadvisor.channeladvisor.com/storefrontprofiles/processfeed.aspx?sfid=101468&i=66115176&mpid=6&dfid=1 as the regulator with this tank http://www.amazon.com/Guerrilla-Air-62ci-3000psi-Aluminum/dp/B001R1MXYC The remote I just purchased at my local paintball store for 20 dollars.

I wouldn't say that propane = relatively low pressure

sure the pressure will drop due to cooling effect but I don't think he needs more than 80 psi with a bbmg...also remember that propane is really dirt cheap

ohh BTW do you think that they add a different odorant to propane in the US and Europe ?? I've seen dozens of posts that suggest that propane stinks but IMO it smells nice... Am I weird or is there a difference between the US and Europe ? :wink:

It shouldn't smell nice, that's the point. In my part of the world they add this stuff to cooking gas (25% propane, 75% butane), so yeah, it stinks ;)

Ah, but if it smells nice, you're less likely to look for a leak ;)

And more likely to spend a rather unhealthy time "smelling" it. :color: :color: :color:
