50 lb. Aluminum CO2 Tank

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 50 lb CO2 capacity: High-volume liquid CO2 charge stretches refill intervals in commercial and multi-light rooms. 6061-T6 aluminum build: About 40% lighter than steel and rust-free in humid grow spaces.
