Co2 Art PRO-ELITE Series v2 The Most Advanced Aquarium Dual Stage CO2 Regulator

The V2 Upgrade: Safety and Stability Perfected

This is not a simple revision—it is the ultimate CO₂ solution built for the long term.

• 100% Guaranteed End-Tank-Dump Prevention: Our advanced Dual Stage Construction ensures a rock-steady output pressure of ~1 PSI stability. As your CO₂ cylinder nears empty, it completely eliminates the final, dangerous pressure surge that kills livestock in single-stage systems.
• W21.8 International Standard: Built specifically to fit the W21.8 x 14 cylinder thread (also known as DIN477 or BS341) used across Europe, the UK, Australia, New Zealand, and many Asian countries. Simply screw it on and start growing.
• Medical-Grade Precision Needle Valve: The V2’s new customized solenoid block integrates a medical-grade needle valve. This provides the most precise control available, allowing you to fine-tune your bubble rate with unparalleled accuracy for optimal plant growth.

Features Built for the Elite Aquascaper

• Next-Generation Solenoid Block: Enjoy a cleaner look, tidier setup, and next-generation reliability from the new fully customized block, perfect for automating your on/off schedule.
• Modular & Expandable Manifold: Easily scale your system! Add extra manifold blocks (sold separately) to run CO₂ into multiple aquariums or power multiple high-demand diffusers from one central unit.
• Stainless Steel Dual Gauges: Monitor your system at a glance. Read your cylinder's gas volume and your precise working pressure so you always know when a refill is due.
• Safe & Cool 12V DC Solenoid: Operates silently with minimal heat, connecting to a universal 100-240V adapter for global compatibility and reliable daily control.
• Integrated Bubble Counter: Conveniently monitor your dosage and flow rate with a clear visual counter, featuring a built-in check valve to prevent water backflow and protect your regulator.
