AC Infinity CO₂ Regulator with Solenoid Valve & Flow Meter – Precision Carbon Dioxide Delivery for Indoor Growing
The AC Infinity CO₂ Regulator with Solenoid Valve & Flow Meter is a professional carbon dioxide delivery system that provides controlled, adjustable CO₂ output for grow tents, grow rooms, greenhouses, indoor gardens, and other controlled environments.
Built with heavy-duty brass construction, the regulator combines a solenoid valve, adjustable gas flow meter, high-pressure tank gauge, CGA-320 threaded inlet, and flexible CO₂ tubing in one convenient system. It allows growers to monitor tank pressure and precisely adjust carbon dioxide flow from compatible pressurized CO₂ cylinders.
For more advanced automation, pair the regulator with a compatible AC Infinity CO₂ Controller to automatically switch CO₂ delivery on and off based on programmed carbon dioxide levels.
Precision CO₂ Flow Meter
The integrated flow meter allows growers to accurately adjust the amount of carbon dioxide released into the growing environment.
The regulator provides a flow range of:
0.5–15 SCFH (Standard Cubic Feet per Hour)
This adjustable range makes it easier to match CO₂ delivery to the size and requirements of the growing space.
The clear vertical flow meter provides an easy visual reference as you adjust output.
High-Pressure Tank Gauge
The built-in pressure gauge measures up to 4000 PSI, allowing growers to monitor the pressure remaining inside a connected CO₂ cylinder.
This makes it easier to tell when the tank is running low and needs replacement or refilling.
The combination of a pressure gauge and flow meter gives users information about both:
- Remaining cylinder pressure
- Current CO₂ delivery rate
Integrated Solenoid Valve
The AC Infinity CO₂ Regulator includes an electrically controlled solenoid valve that opens and closes the gas supply when electrical power is applied or removed.
This feature allows the regulator to work with compatible:
- CO₂ controllers
- Environmental controllers
- Timers
- Outlet controllers
When paired with AC Infinity's compatible 2-outlet CO₂ Controller, CO₂ delivery can automatically activate based on programmed PPM thresholds.
Heavy-Duty Brass Construction
The regulator body is manufactured from durable brass, providing a solid connection between the pressurized CO₂ cylinder and the flow-control system.
Its reinforced construction delivers reliable performance in indoor growing environments while maintaining a secure gas connection.
The solenoid valve assembly is engineered to deliver a steady flow while minimizing unwanted leakage when properly installed.
Standard CGA-320 Tank Connection
The regulator features a CGA-320 threaded inlet, a commonly used connection for standard pressurized carbon dioxide cylinders.
The threaded connection allows the regulator to attach securely to compatible CO₂ tanks, while the interior washer helps create an airtight seal.
Always verify that the CO₂ cylinder uses a compatible CGA-320 valve connection before installation.
Includes 10' CO₂ Tubing
The regulator includes approximately 118.11" (300 cm), or nearly 10', of flexible tubing for distributing carbon dioxide from the regulator into the growing area.
The generous tubing length provides flexibility when positioning:
- CO₂ tanks
- Regulators
- Distribution tubing
- Growing equipment
This is especially useful when the CO₂ cylinder must remain outside the grow tent while gas is delivered inside.
Easy Flow Adjustment
An integrated adjustment knob lets you fine-tune the CO₂ flow rate to your desired output.
The flow meter provides visual feedback during adjustments, allowing growers to select a delivery rate within the regulator's 0.5–15 SCFH range.
This combination of manual adjustment and visual monitoring provides greater control than simple fixed-output gas systems.
Designed for Automated CO₂ Systems
Although the regulator can be controlled manually, its electric solenoid makes it particularly useful in an automated CO₂ management system.
When connected to a compatible CO₂ controller, the system can operate according to real-time carbon dioxide readings.
A typical setup may include:
CO₂ Cylinder → AC Infinity CO₂ Regulator → Distribution Tubing → Grow Area
For automated control:
CO₂ Sensor/Controller → Regulator Solenoid → CO₂ Delivery
This lets the regulator start or stop CO₂ flow based on programmed conditions.
Pairs with the AC Infinity CO₂ Controller
The AC Infinity CO₂ Regulator is an excellent companion to the AC Infinity CO₂ Controller, Smart Carbon Dioxide Monitor 2-Outlet.
Together, the controller monitors carbon dioxide levels and automatically supplies power to the regulator's solenoid when additional CO₂ is needed.
This combination allows growers to create a more integrated carbon dioxide management system that can coordinate:
- CO₂ monitoring
- CO₂ supplementation
- PPM-based activation
- Scheduled operation
- Ventilation management
Ideal for Grow Tents & Grow Rooms
The AC Infinity CO₂ Regulator is suitable for several controlled-environment applications, including:
- Grow tents
- Grow rooms
- Greenhouses
- Indoor gardens
- Controlled-environment agriculture
- Propagation areas
- Indoor horticultural facilities
- Planted aquarium CO₂ systems
Its adjustable flow rate adapts to different enclosure sizes and CO₂ delivery needs.
110V Solenoid Operation
The regulator's solenoid valve operates on 110V electrical power and includes an approximately 72" power cord.
The long cord helps make installation easier when the CO₂ cylinder is positioned away from the controller or electrical outlet.
When using the solenoid with automated controllers, always confirm that the connected controller is electrically compatible with the regulator.
Simple Installation
The regulator is designed to attach directly to a compatible CO₂ cylinder with a CGA-320 threaded valve.
A typical installation involves:
- Confirming that the CO₂ cylinder valve is closed.
- Attaching the regulator securely to the CGA-320 connection.
- Connecting the included tubing.
- Connecting the solenoid to a compatible power source or controller.
- Slightly loosening the adjustment knob before opening the cylinder.
- Slowly opening the CO₂ cylinder.
- Adjusting the flow while monitoring the flow meter.
Always follow the manufacturer's installation and safety instructions when working with pressurized CO₂ cylinders.
