UNS Mini Dual Stage CO2 Regulator
Product Overview
Your regulator is the real control center of your CO₂ system, designed to take 700+ PSI of cylinder pressure and tame it into a safe, steady stream your aquarium can actually use. The redesigned UNS Mini Dual Stage CO₂ Regulator takes the stress out of carbon injection by featuring an advanced dual-stage failsafe that eliminates end-of-tank dumps.

Key Features & Benefits
- Dual-Stage Failsafe Protection: Advanced internal dual-stage engineering prevents catastrophic end-of-tank dumps as cylinder pressure drops low.
- Integrated 12V DC Solenoid: Cool-running electronic solenoid allows seamless automation with standard light timers or smart outlet plugs.
- Universal Thread Compatibility: Comes with a pre-installed standard CGA320 adapter alongside a custom paintball adapter for maximum tank versatility.
- Adjustable 0–50 PSI Output: Precision output knob gives you total control to fine-tune working pressure for ideal micro-bubble diffusion.
- Built-In Pressure Relief Safety: Integrated safety valve automatically vents if working pressure exceeds 51–53 PSI for total peace of mind.

Frequently Asked Questions
1. What is an "end-of-tank dump" and how does a dual-stage regulator prevent it?
When a single-stage cylinder runs low on liquid CO2, the internal pressure drops, causing single-stage regulators to allow an unchecked spike in gas flow that can harm aquarium livestock. The UNS Mini's dual-stage mechanism regulates pressure twice internally, keeping output PSI perfectly stable down to the last drop.
2. Can I use this regulator on a paintball tank out of the box?
Yes! Simply remove the pre-installed CGA320 adapter block to reveal the native paintball threads, or use the included premium paintball adapter for a secure, leak-free connection.
3. Does the electronic solenoid get hot during daily operation?
No. The UNS Mini Dual Stage Regulator utilizes a low-voltage 12V DC solenoid that runs silently and stays cool to the touch even when running for 8–10 hours continuously.
