A 3 phase compressor for boiler testing can probably pull around 3000, but that's an expensive piece of kit. Doesn't it take ridiculously low temp and around 17000 psi to liquefy air? Not something you're going to get under normal circumstances.

Note that HPA tanks are also referred to as high pressure nitrogen, seen as air is around 75+% nitrogen..

Check out this guy's bbmg's, he has them setup for portability- under creations

As an inexpensive regulator, you can use this.

Propane pressure is very dependent on temperature, and it can reach 160+ psi; which obviously needs to be regged down. (unless my sources lie)
well... uhmmm I am sorry to tell you that but your sources lie... 160+ psi doesn't have to be regged down when you use metal... who said you have to use PVC when building a BBMG ?? AFAIK malleable iron fittings & pipes are available in the US
anyway... just look around - most advanced members use metal

Thats awesome roboman! Thanks for that. Luckily I have a Harbor-Freight near my house. That will work perfect
