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

Automatic Climate Control for Your Grow Room.

The GAS Enviro is an environmental control unit that manages grow room conditions by regulating your fan speed. Set your target, plug in your fan, and the controller takes it from there. When the room heats up, the fan ramps up. When conditions come back to your set point, it eases off. You get a stable canopy environment with fewer heat spikes and less plant stress across the crop cycle, without constant manual adjustment.

It works with both AC and EC inline fans, including Systemair Revolution systems, so it drops into new and existing grow room setups.

Key Benefits

• Temperature-based fan control. Adjusts fan speed in response to conditions and holds your set point without manual intervention.
• Stable climate control. Reduces the heat spikes and temperature swings that stress plants and slow growth.
• Fan speed regulation. Stops the fan running flat out when it doesn't need to, which cuts noise and extends motor life.
• AC and EC fan compatible. Works with a wide range of inline fans including the Systemair Revolution AC and EC ranges.
• Plug and play installation. Connect your fan, set your target, and the controller handles the rest.
• Compact design. Small footprint for tents and rooms where controller space is tight.

How It Works

The Enviro reads conditions through its sensor and compares them against your target. As temperature rises above the set point, the controller progressively increases fan speed to bring the room back into range. As it cools, fan speed drops back. That proportional response keeps the environment steady instead of cycling hard on and off the way a basic thermostat does, so you get smoother climate management, quieter running at lower temperatures, and a fan that isn't at full speed when it doesn't need to be.

System Features

• Control type. Temperature-based fan speed regulation.
• Operation. Automatic proportional response.
• Fan compatibility. AC and EC inline fans.
• Installation. Plug and play, no complex wiring.
• Design. Compact, suits grow tents and grow rooms.

Applications

• Grow room fan controller. Automates fan speed to hold canopy temperature steady without manual adjustment.
• Temperature controlled inline fan setup. Works with any compatible AC or EC inline fan to build a responsive ventilation system.
• Hydroponic ventilation automation. Climate automation for hydroponic grow rooms and sealed tent environments.
• Grow tent temperature control. Keeps smaller sealed spaces inside the range plants develop well in.
• Inline fan speed control with thermostat. Cuts full-speed running during cooler periods, lowering noise and energy use.
• Indoor plant climate stabilisation. Steady temperature management across the crop cycle.

What Sets It Apart

The Enviro is built by Global Air Supplies to work as the control point for a Systemair ventilation setup rather than as a generic speed dial. It handles both AC and EC fans, which matters if you're running older RVK-style fans that EC-only controllers won't drive. The proportional control logic means the room stays steady rather than swinging between extremes.

Compatible Ventilation

The Enviro works with both AC and EC inline fans. For a complete ventilation system it pairs with the Revolution EC Silent Inline Fan for variable speed EC control, or the Revolution AC Inline Fan for AC motor performance. Both are made by Systemair.

Frequently Asked Questions

What fans does the Enviro work with?

Both AC and EC inline fans, including the Systemair Revolution range. That's worth knowing, because the newer EC-only controllers won't drive an older AC or RVK-style fan at all. If you're retrofitting, check your fan's wattage against the controller before you buy.

How do I know which GAS controller suits my setup?

It comes down to your fan type and how much you want automated. The EC2 and EC5 are EC-only. The Enviro range runs AC and EC. If you're not sure which unit fits the fans you already own, send us your fan model and we'll confirm it before you order.

Does it qualify for free shipping?

Yes. At $619.95 and 0.8kg it clears the $150 threshold and sits well under the 3kg cap, so it ships free to VIC, NSW, QLD, SA and ACT. WA, NT, Tasmania and remote areas are quoted separately. Most orders to those five states arrive within 2 to 5 business days.
