Frequently Asked Questions
1. Does the UNS 16 Oz. Paintball Cylinder arrive pre-filled with gas?
No. Federal shipping regulations prohibit the transport of pressurized gas cylinders. All cylinders are shipped empty and must be filled or swapped locally at a paintball shop, welding supply store, or homebrew supplier before use.
2. How long will a 16 Oz. paintball tank last on a nano aquarium?
On a standard nano or desktop tank (under 10 gallons) running 1 bubble per second for 8 hours daily, a 16 Oz. paintball cylinder typically lasts between 2 to 4 months before needing a refill.
3. Will this cylinder work with standard CGA320 regulators?
No, not directly. This cylinder features standard paintball threading. It is designed to pair directly with the UNS Mini Dual Stage Regulator (Pairing alternative CO2 regulators voids any warranty claims) or other paintball-compatible regulators (a CGA320 adapter is required to connect to full-size regulators).
