AC Power Adapter for Autopilot CO2 Generators

Replace the Power Supply on Any Autopilot CO2 Generator

The AC power adapter supplies 120V power to the Autopilot CO2 generator's ignition and control circuitry. When the original adapter fails or is lost, replacing it with this direct-fit part restores the generator to operation.

Compatible with all current Autopilot CO2 generator models, the adapter provides the correct voltage for reliable ignition and continuous operation in indoor grow room environments.

Key Features & Benefits

• 120V AC output — delivers the correct voltage for Autopilot CO2 generator ignition and control circuitry.
• Compatible with all Autopilot CO2 generator models — a universal direct replacement for the power adapter included with any Autopilot CO2 generator.
• Direct replacement — replaces the original power adapter when it fails, without requiring modification or rewiring.
• Designed for indoor grow room use — rated for continuous operation in the temperature and humidity conditions typical of indoor growing environments.

Who Should Use the Autopilot CO2 Generator AC Power Adapter

Growers running any Autopilot CO2 generator model who need to replace a failed or missing power adapter to restore normal operation.

Confirming the Issue Before Ordering

Before ordering a replacement adapter, confirm the generator is receiving no power at all — not just failing to ignite. If the generator powers on but doesn't ignite, the issue is more likely a burner, gas supply, or pilot assembly problem rather than the power adapter.

About Autopilot

Hydrofarm's Autopilot brand has supplied CO2, lighting, temperature, and humidity control equipment to indoor growers for more than a decade. This power adapter is one of several direct-fit replacement parts the brand offers to keep an existing CO2 generator running rather than requiring a full replacement.

Frequently Asked Questions

Is this adapter compatible with all Autopilot CO2 generator models?

Yes — it is a universal replacement for the 120V power adapter included with Autopilot CO2 generators across all current burner-count configurations (4, 8, and 10 burner). The connector and voltage output are identical regardless of which generator size you're running.

What voltage does this adapter provide?

120V AC — the standard voltage for Autopilot CO2 generator ignition and control circuits in North American facilities. This matches the original factory-installed adapter, so no rewiring or additional components are needed.

My generator is not igniting — is the power adapter likely the cause?

If the generator shows no signs of receiving power (no display, no indicator lights), a failed adapter is a likely cause. If the generator powers on but fails to ignite, the burner assembly, pilot, or gas supply is the more likely issue.

Can I use a generic 120V adapter instead of this part?

The Autopilot adapter is the recommended replacement to ensure correct voltage and connector fit. Using a generic adapter may work but is not supported by Autopilot.

How do I know if the power adapter itself has failed?

Check whether the generator shows any signs of receiving power at all, such as a display or indicator light — a fully unresponsive unit points to the adapter. If the generator powers on but simply won't ignite, the more likely causes are the burner assembly, pilot, or gas supply rather than the adapter.
