50 lb Aluminum CO2 Cylinder for Commercial Rooms
This 50 lb aluminum CO2 cylinder holds 50 pounds of liquid CO2 in a 6061-T6 aluminum alloy body. It runs an 1,800 psi service pressure under the DOT-3AL specification and tests to 3,000 psi. At about 40% lighter than a comparable steel bottle, it stays rust-free in humid rooms. The CGA-320 outlet threads onto any standard CO2 regulator or solenoid injection setup.
Sizing a CO2 Tank for Larger Grow Rooms
A 50 lb fill carries roughly two and a half times the gas of a 20 lb bottle. That stretches refill intervals in bigger sealed rooms. Actual runtime tracks room volume and target ppm. This refillable aluminum CO2 cylinder ships empty by law, so plan a first fill at a welding or beverage-gas supplier. Pair it with a CO2 regulator and a ppm controller to dose only during lights-on. It feeds the same line for both continuous-flow and solenoid-burst setups.
Key Features
