UNS Mini Dual Stage CO2 Regulator

**This item qualifies for free shipping**

Your regulator is the real control center of your CO₂ system, and it has one job: take that 700‑plus PSI sitting in your cylinder and tame it into a safe, steady stream your aquarium can actually use. The redesigned UNS Mini Dual Stage CO₂ Regulator makes that whole process way less stressful by adding a built‑in dual‑stage failsafe, which prevents the dreaded end‑of‑tank dump that cheaper regulators are notorious for.

Key Features & Benefits

• Advanced dual-stage engineering acts as a constant pressure failsafe to completely prevent catastrophic end-of-tank dumps as your gas supply runs low.
• An electronic 12V DC integrated solenoid allows you to easily put your gas supply on an automatic daily schedule using any standard light timer or smart plug.
• The dual-compatible build features a pre-installed standard CGA320 adapter for bulk tanks alongside an included custom paintball tank adapter.
• An adjustable pressure knob gives you total power to smoothly tune your working output pressure between 0 and 50 PSI for perfect micro-adjustments.
