Description
Product Overview
The AC Infinity CO2 Regulator (model AC-CRA5) is engineered to give growers precise control over carbon dioxide delivery in a variety of indoor cultivation environments. Constructed from heavy‑duty brass and finished in brushed aluminum, the regulator combines durability with a modern aesthetic that fits seamlessly into professional grow rooms, tents, and greenhouse setups. The integrated solenoid valve provides rapid response to pressure changes, while the built‑in flow meter measures gas flow from 0.5 to 15 standard cubic feet per hour, allowing users to fine‑tune CO2 output to match plant demand. A clear pressure gauge ranging from 0 to 4000 PSI offers real‑time insight into tank pressure, helping prevent over‑pressurization and ensuring safety. The regulator operates on standard 110‑volt AC power, eliminating the need for batteries and simplifying installation. Its compact dimensions (9.25 x 7.56 x 4.65 inches) and weight of 2.7 pounds make it easy to mount on tanks or integrate into existing gas lines using the CGA‑320 inlet. Designed for compatibility with a wide range of CO2 tanks and hose tubing, this unit serves as a core component of any CO2 enrichment system, delivering consistent, leak‑free performance day after day.

Usage
Growers looking to boost photosynthetic efficiency can deploy the AC Infinity CO2 Regulator in multiple scenarios. In a dedicated grow tent, the regulator connects directly to a CO2 tank and distributes gas through a network of tubing to reach every plant canopy, maintaining optimal concentrations of 800‑1200 ppm during the light cycle. In larger greenhouse environments, the regulator can be paired with multiple distribution manifolds, ensuring uniform CO2 levels across expansive rows of crops. The audible alarm alerts users to pressure deviations, making it suitable for both hobbyist setups and commercial operations where continuous monitoring is essential. Because the device is built to AC power, it can be integrated into existing electrical infrastructure without the need for additional power supplies. Its robust brass construction resists corrosion from humid grow environments, and the brushed aluminum finish reduces glare, preserving the visual integrity of the grow space. Whether used in a small personal grow room or a professional hydroponic facility, the regulator’s precise flow control and reliable sealing prevent wasteful gas loss, reducing operational costs while maximizing plant health.

FAQ
What size CO2 tanks are compatible with this regulator?
The AC Infinity CO2 Regulator is compatible with standard 20‑liter and larger CO2 tanks that feature a CGA‑320 inlet. Its adjustable fittings allow secure connections to a variety of hose diameters, making it versatile for both small‑scale hobbyist tanks and larger commercial cylinders.
How do I calibrate the flow meter for accurate measurements?
Calibration is straightforward: first, ensure the regulator is disconnected from the CO2 source. Then, use a calibrated reference flow meter to compare readings while adjusting the regulator’s flow knob until the displayed value matches the reference. AC Infinity provides a detailed calibration guide in the user manual, and the process typically takes only a few minutes.
Is the audible alarm loud enough for a noisy greenhouse environment?
Yes, the alarm is designed to emit a clear, high‑volume tone that can be heard over typical greenhouse background noise, such as fans and pumps. The sound level complies with industry safety standards, ensuring that any pressure irregularities are promptly noticed.
Can this regulator be used with other gases besides CO2?
While the regulator is optimized for carbon dioxide, its robust construction and pressure rating allow it to handle other inert gases like nitrogen or argon, provided the gas is compatible with the solenoid valve materials and the user follows appropriate safety guidelines.
What maintenance is required to keep the regulator operating optimally?
Regular maintenance includes checking the solenoid valve for signs of wear, cleaning the pressure gauge window to maintain readability, and inspecting hose connections for tightness. It is recommended to perform a full system check every six months and replace the flow meter or valve components as needed based on usage intensity.
