Pressure Regulation: Reduces high pressure from the CO2 cylinder to a lower output ranging from 0- 4.5 bar (0- 65.27 psi) constant pressure output for stable use in the aquarium.

Flow Control: Equipped with brass-made needle valve. Allows precise adjustment of the CO2 flow rate accurate to one bubble every 20 seconds. This is crucial for maintaining the optimal CO2 levels for plant growth and overall aquarium health.

Pressure Gauge: This pressure regulator features a single gauge to display output pressure accurately and reliably. It provides a clear indication of the remaining CO2 and the output pressure, ensuring timely refilling and proper adjustment.

Durability and Safety: Built with durable materials to withstand high pressure and ensure long-term reliability. The carbon dioxide regulator is brass made with stainless steel made needle for gas throughflow. Aluminum Alloy designed cylinder holder is stable for place and it also makes this whole set easy to store. With excellent air-tight sealing for both inlet and outlet, ensuring stable and reliable system operation.
