Wyin Aqua WY30-01S Dual Stage CO2 Regulator with Solenoid

Dual Stage and Dual Gauge Model

Wyin Aqua WY30-01S is a premium dual-stage aquarium CO2 regulator designed for planted aquariums that require stable working pressure, precise CO2 adjustment and reliable automated control.

The regulator combines a true dual-stage pressure-reduction system with dual pressure gauges, an integrated 12V DC solenoid valve, precision needle valve and quick-plug bubble counter. It is suitable for both single planted aquariums and expandable multi-tank CO2 installations.

For aquarists who want a more stable alternative to basic single-stage regulators, the WY30-01S provides better pressure control as cylinder pressure changes, while its modular manifold system makes future expansion easy.

Key Features of Wyin Aqua WY30-01S

• True dual-stage CO2 regulator design
• Dual pressure gauges for cylinder and working-pressure monitoring
• Integrated 12V DC solenoid valve
• Precision needle valve for fine bubble-rate adjustment
• Quick-plug bubble counter for convenient tubing connection
• Adjustable working pressure using the main regulator knob
• Expandable modular CO2 output system
• Supports up to 8 bubble-counter / manifold modules
• Durable aluminium alloy and brass construction
• Designed for pressurised planted aquarium CO2 systems
• Compatible with several standard CO2 cylinder thread types

Why Choose a Dual Stage CO2 Regulator?

A dual-stage regulator reduces cylinder pressure through two regulation stages instead of a single pressure-reduction stage.

This design helps maintain more stable working pressure as the CO2 cylinder empties and is particularly useful in planted aquariums where a predictable CO2 injection rate is important.

More stable output pressure can also reduce the likelihood of sudden changes in gas flow near the end of the cylinder.

Dual Pressure Gauges

The WY30-01S includes two large gauges for convenient monitoring of the pressurised CO2 system.

• Cylinder Pressure Gauge: Helps monitor pressure inside the CO2 cylinder
• Working Pressure Gauge: Displays the regulated output pressure supplied to the CO2 system

The dual-gauge configuration gives the aquarist a clearer view of both cylinder and operating pressure during normal use.

Integrated 12V DC Solenoid Valve

The built-in 12V DC solenoid valve allows the CO2 supply to be switched automatically using a timer or compatible controller.

This makes it possible to synchronise CO2 injection with the aquarium lighting schedule instead of continuously injecting gas throughout the day and night.

A typical planted aquarium routine is to start CO2 before the lighting period and switch it off before the lights go out.

Precision Needle Valve for Fine CO2 Adjustment

The integrated precision needle valve allows small adjustments to the CO2 flow rate.

The required injection rate varies depending on factors such as:

• Aquarium volume
• Plant density
• Lighting intensity
• Water circulation
• Diffuser efficiency
• CO2 distribution inside the aquarium

Always increase CO2 gradually and monitor aquarium livestock carefully while making adjustments.

Quick-Plug Bubble Counter

The WY30-01S includes a quick-assemble bubble-counter module designed for convenient CO2 tubing installation.

The bubble counter provides a simple visual reference for gas flow and helps make fine adjustments easier.

The regulator uses a 6 mm CO2 outlet, suitable for common pressure-rated aquarium CO2 tubing systems.

Adjustable Working Pressure

The WY30-01S allows working pressure to be adjusted using the main regulator control knob.

The specified output-pressure range is approximately 0–0.6 MPa, allowing the regulator to be configured for different aquarium CO2 equipment such as diffusers, atomisers and inline CO2 diffusers.

Expandable Multi-Tank CO2 Regulator

One of the strongest features of the WY30-01S is its modular output system.

Additional Wyin Aqua Expandable Manifold Blocks can be added to create additional independently controlled CO2 outlets.

WYIN specifies support for up to 8 bubble-counter modules, making the regulator suitable for multiple planted aquariums supplied from a single CO2 cylinder.

This can be particularly useful for:

• Multiple planted aquarium setups
• Aquascaping studios
• Aquarium shops and display tanks
• Aquatic plant holding systems
• Hobbyists planning future aquarium expansion

Benefits of One CO2 Cylinder for Multiple Aquariums

An expandable manifold system can reduce the need to purchase separate regulators and CO2 cylinders for every aquarium.

Benefits include:

• One regulator serving several planted aquariums
• Separate needle-valve adjustment for each outlet
• Reduced equipment duplication
• Cleaner CO2 installation
• Easy future expansion
• More efficient use of a larger refillable CO2 cylinder

WY30-01S Pressure Specifications

• Maximum / Working Input Pressure: 15 MPa
• Adjustable Output Pressure: 0–0.6 MPa
• CO2 Outlet Diameter: 6 mm

Always use pressure-rated tubing and fittings with a pressurised CO2 system.

Compatible CO2 Cylinder Threads

WYIN lists the WY30-01S platform with several available cylinder connection standards, including:

• G5/8
• W21.8
• CGA320
• M22
• G3/4

The Aqua Zones supplied version should always be matched to the thread type of the CO2 cylinder being used. Confirm cylinder compatibility before installation.

How to Install the WY30-01S

1. Keep the CO2 cylinder upright and ensure the cylinder valve is fully closed.
2. Confirm the cylinder thread and regulator connection are compatible.
3. Check the regulator sealing washer or O-ring.
4. Securely attach the regulator to the cylinder.
5. Connect pressure-rated CO2 tubing to the bubble-counter outlet.
6. Connect the tubing to the aquarium diffuser or inline diffuser.
7. Connect power to the solenoid valve.
8. Open the cylinder valve slowly.
9. Check all regulator and tubing connections for gas leaks.
10. Set the required working pressure.
11. Use the needle valve to gradually adjust the bubble rate.

Leak Testing After Installation

Leak testing is important whenever a regulator, manifold or CO2 tubing connection is installed or changed.

Even a small gas leak can empty a CO2 cylinder much faster than expected and cause unstable CO2 delivery.

Check the cylinder connection, regulator fittings, manifold modules and tubing joints carefully before regular operation.

WY30-01S vs WY30-02S

The WY30-01S is the premium Pro Series model and uses a true dual-stage pressure-reduction design.

The Wyin Aqua WY30-02S is another dual-gauge regulator option for planted aquarium CO2 systems.

For users prioritising dual-stage pressure stability and a premium expandable regulator platform, the WY30-01S is the stronger choice.

WY30-01S vs Dual Output CO2 Regulator

If two aquarium outlets are required immediately, the Wyin Aqua WY30-02S-D Dual Output CO2 Regulator is another option.

The WY30-01S is particularly useful when you want a true dual-stage regulator and prefer to expand the number of CO2 outlets gradually using modular manifold blocks.

Important CO2 Safety Guidance

Pressurised CO2 cylinders should always be stored upright and securely supported.

Do not force incompatible cylinder threads or regulator fittings.

Open the CO2 cylinder valve slowly after installation and always inspect the complete system for leaks.

When adjusting aquarium CO2, make changes gradually and carefully monitor fish, shrimp and other livestock.
