I obtained a Full 20 lb CO2 Cyclinder. I thought I was getting CO2. I just notice a small orange printed stickly label that says BEV Gas. What is this? Online, it could be anywhere from 100% CO2 to only 25% CO2. It has the standard CO2 Regulator, so I would believe it it mostly if not all CO2. Unfortunately, I got it some time ago and no longer have the contact info from where I got it.
