GAS EC2 Fan Controller | EC Fan Speed Control and Balancer for Grow Room Ventilation

Small Controller. Complete EC Fan Control.

The GAS EC2 is a compact but capable EC fan controller built for growers who want precise control over their intake and extraction ventilation without the complexity of a full climate management system. Plug it directly into your EC fan, set your maximum and minimum fan speeds for the extraction side, and the EC2 handles the rest. The intake fan follows automatically, maintaining the negative pressure balance you set without requiring separate adjustment. No power pack, no extra wiring, no unnecessary complexity.

Built-in fan balancing and negative pressure control in a compact unit that draws power directly from your EC fan. For growers who want clean, precise EC fan management in a straightforward package, the EC2 is the direct solution.

Key Benefits

• EC Fan Control and Balancing. Controls and balances both intake and extraction EC fans from a single unit, keeping your ventilation system in sync without manual adjustment of each fan independently.
• Set Maximum and Minimum Fan Speeds. Define the operating range for your extraction fan. The intake fan follows automatically, maintaining the correct balance across the full speed range.
• Negative Pressure Control. Dial in the ideal negative pressure for your grow space, preventing odours from escaping without relying on a separate balancer unit.
• No Power Pack Required. The EC2 draws power directly from your EC fan via the active cable. Cleaner setup, fewer components, one less point of failure.
• Direct EC Fan Connection. Plugs directly into all EC fan ranges via the included active cable. No adaptor required for compatible fans.
• Compact Design. Small footprint for clean controller setups in grow tents and rooms where space is limited.
• 12-Month Warranty. Backed by GAS manufacturer warranty.

How It Works

The EC2 connects directly to your EC fan via the active cable and draws its operating power from the fan itself. Set your maximum and minimum fan speeds for the extraction fan using the controller, and set your target negative pressure. The EC2 manages the extraction fan within your defined speed range and automatically adjusts the intake fan to maintain the negative pressure balance you have set. The result is a sealed, odour-controlled grow space with balanced airflow, managed from a single compact controller without any additional hardware.

Applications

• EC Fan Speed Control for Grow Rooms. Set and maintain precise fan speeds for both intake and extraction without manual adjustment of each fan independently.
• Grow Room Negative Pressure Management. Built-in pressure control keeps your space sealed against odour escape without a separate balancer unit.
• Hydroponic Ventilation Automation. Balanced intake and extraction airflow for stable temperature and humidity conditions across the crop cycle.
• Grow Tent EC Fan Controller. Compact design suits tent setups where space is limited and a clean, minimal controller is preferred.
• EC Fan Balancing System. Synchronises intake and exhaust fans automatically once extraction speed range and negative pressure are set.
• Simple EC Fan Control Upgrade. A straightforward step up from manual speed controllers for growers moving to EC fan systems.

What Sets It Apart

The EC2 does the core job of EC fan control well and without excess. Fan balancing, negative pressure control, and adjustable speed range in a compact unit that needs no power pack and plugs directly into your fan. For growers who want reliable EC fan management without temperature automation or auxiliary equipment control, the EC2 is the clean, focused solution. It is also the most compact option in the GAS controller range, making it the practical choice for tent setups and smaller rooms where controller footprint matters.

EC2 and the Revolution EC: A Complete Ventilation System

The GAS EC2 pairs directly with the Revolution EC Silent Inline Fan by Systemair for a complete, balanced EC ventilation system. The Revolution EC delivers high static pressure, ultra-quiet operation, and precise variable speed response. The EC2 manages both intake and extraction fans, sets negative pressure, and keeps the system balanced automatically. Together they form a ventilation setup that is quiet, efficient, and fully controlled from a single compact unit.

Frequently Asked Questions

What fans is GAS EC2 Fan Controller compatible with?

GAS EC2 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 EC2 Fan Controller if you are retrofitting to an existing setup.

How does GAS EC2 Fan Controller automate my grow room climate?

GAS EC2 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 EC2 Fan Controller with both my intake and exhaust fans?

Most fan controllers including GAS EC2 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 EC2 Fan Controller ship fast within Australia?

Yes — GAS EC2 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.
