UNS Pro Dual Stage CO2 Regulator
Product Overview
When managing high-tech layouts, large displays (20 gallons and above), or splitting gas across a multi-tank setup, you need the ultimate level of precision and pressure stability. The UNS Pro Dual Stage CO₂ Regulator is a commercial-grade powerhouse wrapped in a beautiful Space Grey finish. Featuring a sophisticated dual-stage design, it monitors both your internal tank pressure and your direct working output pressure simultaneously, eliminating end-of-tank dumps while providing smooth, high-pressure output for large systems.

Key Features & Benefits
- Dual-Stage Failsafe Protection: Advanced dual-stage engineering acts as a constant pressure failsafe to completely prevent catastrophic end-of-tank dumps as your gas supply runs low.
- Modular Manifold System: An expandable bubble counter manifold lets you split your gas supply seamlessly to feed multiple tanks independently from a single regulator.
- Dual High-Precision Gauges: Monitors both raw cylinder tank pressure (0–4,000 PSI) and exact working output pressure (0–160 PSI) for complete system transparency.
- Integrated Electronic Solenoid: Cool-running 12V DC solenoid enables automated daily dosing control when paired with standard light timers or smart plugs.
- High-Pressure 70 PSI Range: Heavy-duty adjustable control knob gives you smooth control over working output pressure up to an impressive 70 PSI for inline atomizers.

Frequently Asked Questions
1. Can I expand this regulator to run CO2 on multiple aquariums?
Yes! The UNS Pro Dual Stage Regulator includes modular manifold blocks with needle valves and bubble counters. You can add additional manifold blocks to run up to several aquariums independently off a single CO2 cylinder.
2. Why is a higher working pressure (up to 70 PSI) important?
High working pressure is crucial when using inline diffusers, reactor chambers, or dense ceramic diffusers that require high push pressure (often 30–45+ PSI) to atomize micro-bubbles effectively.
3. Will the UNS Pro Regulator fit paintball cylinders?
The UNS Pro features standard CGA320 threads designed for full-size aluminum tanks. While a CGA320-to-paintball adapter can be used, we recommend pairing the UNS Pro with standard 2.5LB, 5LB, 10LB, or 20LB CGA320 cylinders for optimal stability.
