FZONE Dual Stage CO2 Regulator Aquarium Adjustable Output Pressure Pro Series with DC Solenoid and Integrated High Precision Needle Valve Bubble Counter (dual stage)

Dual stage construction & adjustable output pressure. Dual stage construction provides stable output pressure regardless of how much CO2 gas remains inside the CO2 cylinder, eliminating unpredictable catastrophes such as an end-of-tank-dump (EoTD). The output pressure is adjustable from 0-65 PSI based on customers’ different needs. Modular manifold block design. Power two tanks with independent control. Features two independent manifold blocks, each with its own high-precision needle valve. Control CO2 for a single aquarium or for two separate aquariums independently from one regulator—perfect for multi-tank owners. Safety and precision in mind. Our regulator has a built-in safety valve. It will open automatically to release the pressure when it exceeds 100 PSI. The integrated needle valve is precise. The CO2 output can be adjusted to as low as 1 bubble every 3 seconds. Solenoid runs on 12V DC instead of conventional 120V AC. This regulator adapts to 12V DC, which is more stable and consumes less power. The solenoid is safe to touch and is very quiet. Attention. Suitable for W21.8 side opening tanks! Installation tools are included. Fzone will offer a one-year warranty, round-the-clock service, and you can reach out to us at any time for any product-related concerns.
