Description: Uses: This type of splitter allows multiple grass tanks to share a CO2 cylinder set. One-piece design, beautiful and convenient. Each branch has independent fine-tuning, and the air volume adjustment is performed separately, so there is no need to worry about uneven output. Each branch can be completely closed, and this can be directly closed when not in use. The fine-tuning of the shunt can be done. A professional-grade anti-reverse bubbler can be installed to make the adjustment more rapid.
