GAS Enviro Fan Controller | Temperature-Controlled Grow Room Ventilation Australia

Simple, Reliable Temperature Control for Your Grow Room.

The GAS Enviro Fan Controller is a proven environmental control unit built for growers who want automated temperature-based airflow management without the complexity of advanced programmable systems. Set your target temperature with the dial, plug in your fan, and the controller takes it from there. When your room heats up, the fan ramps up. When temperature drops back to your set point, it eases off. The result is a stable canopy environment, reduced heat spikes, and less plant stress across the full crop cycle, without constant manual adjustment.

Compatible with both AC and EC inline fans including high-performance Systemair ventilation systems, the GAS Enviro integrates cleanly into new and existing grow room setups. For growers who want reliable climate automation at a straightforward price point, this is the controller that gets the job done.

Key Benefits

• Temperature-Based Fan Control. Automatically adjusts fan speed in response to temperature changes, maintaining your set point without manual intervention.
• Simple Dial Interface. Fast setup and intuitive operation. No programming, no menus, no complexity.
• Stable Climate Control. Reduces heat spikes and temperature fluctuations that cause plant stress and slow growth rates.
• Fan Speed Regulation. Prevents unnecessary full-speed operation, reducing noise and extending fan motor life.
• Plug and Play Installation. No programming required. Connect your fan, set your temperature, and the controller manages the rest.
• AC and EC Fan Compatible. Flexible integration with a wide range of inline fans including Systemair and Blauberg ventilation systems.
• Compact Design. Space-efficient footprint for clean controller setups in grow tents and rooms.
• Reliable Operation. Proven controller design built for consistent, long-term use in grow environments.

How It Works

The GAS Enviro reads ambient temperature via its sensor and compares it against your dial-set target. As temperature rises above your set point, the controller progressively increases fan speed to bring conditions back into range. As the room cools, fan speed reduces accordingly. This proportional response keeps your environment stable without the on and off cycling that causes temperature swings in basic thermostat setups. The result is smoother climate management, quieter operation at lower temperatures, and a fan that is not running at full speed when it does not need to be.

Applications

• Grow Room Fan Controller. Automates fan speed to maintain stable temperature across the canopy without manual adjustment.
• Temperature Controlled Inline Fan Setup. Works with any compatible AC or EC inline fan to create a responsive ventilation system.
• Hydroponic Ventilation Automation. Entry-level climate automation for hydroponic grow rooms and sealed tent environments.
• Grow Tent Temperature Control. Keeps smaller sealed environments within the optimal temperature range for healthy plant development.
• Inline Fan Speed Controller with Thermostat. Reduces full-speed fan operation during cooler periods, lowering noise and energy use.
• Indoor Plant Climate Stabilisation. Consistent temperature management for improved growth rates and reduced environmental stress.

What Sets It Apart

The GAS Enviro does one thing and does it well: it keeps your grow room temperature stable by automating your fan. There are no menus to navigate, no sensors to calibrate, and no programming to work through. The dial interface means setup takes minutes, and the proportional control logic means your environment stays stable rather than swinging between extremes. For growers who want reliable automation without the overhead of a full climate control system, the GAS Enviro is the practical starting point.

Enviro vs Enviro V2: Which GAS Controller Is Right for You?

Both controllers automate your grow room ventilation in response to environmental conditions. The difference is in how much of your environment you want to control.

• GAS Enviro (this model). Temperature-based fan speed control with a simple dial interface. Fast setup, no programming, reliable operation. Best for growers wanting straightforward automation, smaller grow tents, and budget-conscious builds where temperature control is the primary need.
• GAS Enviro V2. Adds humidity control, programmable sockets for auxiliary equipment, an integrated fan balancer for intake and exhaust sync, and an LCD display with advanced control logic. Best for larger or more advanced setups where full environmental automation and yield optimisation are the goal.

Frequently Asked Questions

What fans is GAS Enviro Fan Controller compatible with?

GAS Enviro Fan Controller 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 Enviro Fan Controller if you are retrofitting to an existing setup.

How does GAS Enviro Fan Controller automate my grow room climate?

GAS Enviro Fan Controller 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 Enviro Fan Controller with both my intake and exhaust fans?

Most fan controllers including GAS Enviro Fan Controller 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 Enviro Fan Controller ship fast within Australia?

Yes — GAS Enviro Fan Controller 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.
