Aqua-Noa CO₂ Check Valve Profi

AQUA-NOA CO₂ Check Valve Profi Metal

Protect your valuable CO₂ pressure regulator from irreversible water damage with the AQUA-NOA CO₂ Check Valve Profi. This robust metal check valve is an essential component of any professional CO₂ system.

Why is a check valve essential?

When a CO₂ cylinder runs empty or the supply is stopped, a pressure difference can occur. This may cause aquarium water to flow back through the tubing into your technical equipment. Such backflow can lead to corrosion and internal damage to the pressure regulator.

The benefits of the Profi Metal version:

• Maximum protection: Effectively prevents moisture from entering the pressure regulator, which is essential to avoid internal corrosion.
• Durable metal construction: Unlike plastic variants, this metal model is designed to withstand the standard working pressure of approximately 2 bar and offers a significantly longer service life.
• Reliable connection: Designed for a leak-free connection with standard 4/6 mm CO₂ tubing.
• Professional finish: A sleek design that seamlessly matches the AQUA-NOA Profi and Basic pressure regulators.

Specifications & Installation

• Compatibility: Suitable for any CO₂ system using standard 4/6 mm tubing.
• Installation: Install the valve in the tubing line between the pressure regulator and the diffuser to prevent backflow. Note: The check valve features an arrow indicating the direction of CO₂ flow. Make sure this direction is followed for proper operation.
