GAS to Stereo Single Adapter | EC Fan Controller Compatibility Interface for Grow Room Ventilation

The Right Connection Between Your GAS Controller and Stereo-Input EC Fan.

The GAS to Stereo Single Adapter is a precision signal interface engineered by Global Air Supplies to enable full control of EC (electronically commutated) inline fans via compatible GAS climate and fan controllers. Where the RJ11 adaptor serves fans with RJ11 inputs, this adapter outputs a stereo jack signal, making it the correct interface for EC fans that use stereo input connections. Without the right adaptor in place, your GAS controller cannot communicate with your EC fan, meaning fan speed modulation, temperature response, and environmental automation are unavailable regardless of how capable your controller is.

If you are running a GAS controller with a stereo-input EC fan, this adapter is the component that completes the control chain. Plug and play installation, stable signal transmission, and a compact inline footprint that keeps your setup clean and your system fully functional.

Key Benefits

• Stereo Signal Output. Converts GAS controller output to a stereo jack signal, enabling direct communication with stereo-input EC fans for full speed modulation and environmental response.
• Broad GAS Controller Compatibility. Works with the full range of compatible GAS controllers including the Enviro, Enviro V2, EC5, Enviro 4, and EC2.
• Plug and Play Setup. Simple inline installation. No wiring, no tools, no configuration required.
• Stable Signal Transmission. Maintains accurate, consistent fan response across the full speed range for smooth fan ramping and precise environmental control.
• Compact Design. Minimal footprint within your system. Sits cleanly between controller and fan without adding bulk to your setup.
• Essential Compatibility Tool. Required for stereo-input EC fan setups where a direct controller connection is not possible without signal conversion.

How It Works

GAS controllers output a control signal to regulate EC fan speed. Stereo-input EC fans require a stereo jack connection to receive that signal. The GAS to Stereo Single Adapter sits between the controller and the fan, converting the controller output to a stereo jack signal so the fan can receive and act on speed commands accurately. Signal transmission is stable across the full operating range, ensuring the fan responds correctly to temperature changes, speed adjustments, and environmental triggers from your controller. The result is a fully integrated ventilation system where your controller and fan communicate as intended.

What Sets It Apart

This is a precision accessory engineered for the specific signal requirements of GAS controllers and stereo-input EC fans. A generic stereo cable may not maintain signal integrity at the voltage and frequency levels used by EC fan control systems, leading to erratic fan behaviour, incorrect speed response, or no communication at all. The GAS to Stereo Single Adapter is the confirmed, compatible solution for the controller and fan combinations it is designed to support. It is also worth noting the difference between this adapter and the GAS to RJ11 Adaptor: both convert GAS controller signals for EC fan use, but the stereo adapter is for fans with stereo jack inputs, while the RJ11 adaptor is for fans with RJ11 inputs. Choosing the correct one for your fan is essential.

Complete Your GAS Ventilation Control System

This adapter is one component in a complete EC fan control system. Here is how the full GAS ecosystem fits together:

• GAS Enviro Fan Controller. Entry-level temperature-based fan speed control. Simple dial interface, plug and play. View the GAS Enviro Fan Controller.
• GAS Enviro V2 Fan Controller. Adds humidity control, dual programmable sockets, integrated fan balancing, and LCD display for full environmental automation. View the GAS Enviro V2 Fan Controller.
• GAS EC5 Fan Controller. Purpose-built for EC fans with Reactive Temperature Technology, integrated fan balancing, negative pressure control, and no power pack required. View the GAS EC5 Fan Controller.
• GAS to RJ11 Adaptor. The equivalent interface for EC fans that use RJ11 inputs rather than stereo jack connections. View the GAS to RJ11 Adaptor.

Pair the correct adapter with your GAS controller and EC fan to complete a fully integrated, automated grow room ventilation system.

Frequently Asked Questions

What fans is GAS to Stereo Single Adapter compatible with?

GAS to Stereo Single Adapter is designed to work with compatible inline fans. EC controllers require EC-motor fans for full variable-speed control — they are not compatible with standard AC-motor fans. AC fan controllers work with standard single-phase AC fans. Check the compatibility list for your specific fan model before purchasing GAS to Stereo Single Adapter if you are retrofitting to an existing setup.

How does GAS to Stereo Single Adapter automate my grow room climate?

GAS to Stereo Single Adapter monitors temperature and/or humidity via its onboard or external probe and automatically adjusts fan speed to maintain your target setpoints. When temperature rises above your target, fan speed increases to extract warm air. When temperature drops, fan speed reduces to conserve heat. This removes the need for manual fan adjustments and keeps your grow room dialled in 24/7.

Can I use GAS to Stereo Single Adapter with both my intake and exhaust fans?

Most fan controllers including GAS to Stereo Single Adapter are designed to control your primary exhaust fan. Some models include dual-channel control for both intake and exhaust. Check the number of output channels and maximum load rating before connecting multiple fans — never exceed the controller's maximum amperage rating.

Does GAS to Stereo Single Adapter ship fast within Australia?

Yes — GAS to Stereo Single Adapter ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
