WYINAQUA WY30-01E is a dual-stage CO₂ regulator for aquariums, featuring two large pressure gauges, an electric valve and a built-in programmable timer. It allows precise pressure adjustment and automatic CO₂ ON/OFF control according to a preset schedule.
The regulator features a W21.8 inlet thread, a 6 mm CO₂ tubing outlet and a modular design supporting up to 8 bubble counter modules.
WYINAQUA WY30-01E – Dual-Stage CO₂ Regulator with Timer
WYINAQUA WY30-01E is a dual-stage CO₂ regulator designed for planted aquariums and aquascaping systems where precise and controlled CO₂ delivery is required.
The model combines dual-stage pressure regulation, two large pressure gauges, an electric valve and a built-in programmable timer. This allows you to adjust the working pressure while also automatically controlling when CO₂ is supplied according to a preset schedule.
Dual-Stage CO₂ Pressure Regulation
WY30-01E uses a dual-stage design for pressure regulation. The main adjustment is performed using the central adjustment knob, allowing the working pressure to be set according to the requirements of the CO₂ system.
The dual-stage construction is suitable for aquariums where stable and controlled CO₂ delivery is important.
Built-in Programmable Timer

One of the key features of the WY30-01E is its built-in programmable timer.
The timer controls the electric valve and allows you to set specific times for automatically turning the CO₂ supply on and off.
This means that no separate external timer is required to control the CO₂ valve. The operating schedule can be programmed directly through the control module integrated into the regulator.
This is particularly convenient for planted aquariums, where CO₂ delivery is normally coordinated with the daily lighting schedule.
Electric Valve
WY30-01E features an electric valve for automatic control of the CO₂ flow.
The valve is controlled by the built-in timer and allows the CO₂ supply to be automatically stopped and restored according to the programmed schedule.
Two Large Pressure Gauges
The regulator is equipped with two large pressure gauges, making it easier to monitor the pressure within the CO₂ system.
The large gauge faces allow the readings to be viewed quickly and conveniently during setup and everyday use.
W21.8 Inlet Thread
This version of the WYINAQUA WY30-01E features a W21.8 inlet thread for connection to a compatible CO₂ cylinder.
Before installation, make sure that the thread on your CO₂ cylinder is compatible with W21.8.
Quick-Connect Design
WY30-01E features a quick-assemble design, making installation and configuration of the CO₂ system easier.
The regulator is designed for use with 6 mm CO₂ tubing.
Modular Construction

The modular design allows the system to be expanded according to the aquarist's needs.
Up to 8 bubble counter modules can be added to the regulator, allowing a multi-line CO₂ system to be configured.
The first module is replaceable, while the modular construction provides two connection options.
Precise Pressure Adjustment
The central adjustment knob allows the working pressure of the system to be adjusted according to the requirements of the aquarium.
This makes the WY30-01E suitable for different planted aquarium and aquascaping configurations.
Aluminum Construction with Anodized Finish
The regulator body is made from aluminum alloy and features an anodized Gun Gray finish.
The compact construction combines functionality, durability and a modern appearance suitable for contemporary aquarium systems.
Suitable for Planted Aquariums and Aquascaping
WYINAQUA WY30-01E is designed for use in CO₂ systems for planted aquariums.
The combination of dual-stage pressure regulation, two pressure gauges, an electric valve and a programmable timer provides convenient and automated control of CO₂ delivery.
The modular design also makes it suitable for more complex systems where one CO₂ source is used to supply several separate lines.
How Does the WY30-01E Work?

The CO₂ cylinder is connected to the regulator using the W21.8 thread.
The regulator reduces the gas pressure and allows the working pressure to be adjusted using the central adjustment knob.
After the pressure has been set, CO₂ flows through the outlet to the other components of the system, such as the bubble counter, CO₂ tubing and diffuser.
The electric valve controls the CO₂ supply, while the built-in timer determines when the system is switched on or off according to the programmed schedule.
