Dual Stage CO2 Regulator
Essential Role of CO2 Regulators in Aquarium Systems
CO2 regulators are vital for planted aquarium systems, providing efficient dispensing of the gas from the high-pressure cylinder to the aquarium. With pressures in the gas cylinder exceeding 700 psi, the regulator plays a pivotal role in maintaining a controlled release through airline tubing and into the aquarium. The Dual Stage structure provides stable output regardless of the pressure within the CO2 cylinder, preventing end-of-tank-dump catastrophes.
- Adjustable output pressure to 5 Bar/70 PSI
- Built-in failsafe mechanism
- Bubble counter manifold splits CO2 into multiple tanks
Stable CO2 Dispensation with Dual-Stage Precision
UNS CO2 regulators are designed with a high-precision structure for controlled and consistent distribution of CO2 for optimal plant health. The bubble counter system provides an additional layer of customization, allowing you to precisely dial in the dosage for your specific aquarium needs. Installation is simple, and all tools are provided, making it ideal for both beginners and experienced aquarists, enhancing the process of caring for plants in an aquarium.
Built in Solenoid
Easily manage your CO2 supply with the built-in solenoid, providing seamless and efficient management for optimal performance and precision.
Solid Material for Durability
Designed for strength and resilience, the construction of the CO2 Regulator stands for its sturdiness, offering a dependable foundation for various applications.
Sleek Appearance
Available in a beautiful space gray color finish. Presenting a modern and polished look not only complements but also elevates the overall appearance of the cabinet.
Mini and Pro Models for Precision and Professional Applications
UNS Regulators are available in 2 sizes, Pro and Mini. The Pro version uses a CGA320 thread-type connection and supports multiple manifolds with independent adjustment valves. This allows you to daisy chain your CO2 canister to support multiple tanks. The Mini version uses a 5/8-18UNF-PAINTBALL thread type connection with a 0–50 PSI output pressure gauge and a safety-conscious pressure relief valve set at 51–53 PSI. For versatile and professional applications, the Pro features a 0-160 PSI output pressure gauge, a 0-4000 PSI tank/high-pressure gauge, and a 100 PSI pressure relief valve. Whether you prioritize precision or advanced functionality, our CO2 Regulator series meets your needs with the Mini and Pro options.

What a nightmare so far, decieded to upgrade my fzone to the UNS dual stage. Other than not being dual stage I had no issues with the fzone, I just didn’t really like the build quality. Fast forward, installed the UNS get no air pressure, no leaks but no co2. Have sent videos and pictures to UNS Customer service, it’s like turtle mail. One reply per day and no answers. A tank that is used to getting co2 and then doesn’t, is a problem.

Great product. I use it for my aquarium CO2 system and it’s awesome. I put it on a timer and it works with cartridges, paintball tanks and 5 g tanks.
