GAS Enviro V2 Fan Controller | Closed-Loop Climate Automation for Hydroponic Grow Rooms

Closed-Loop Climate Control That Drives Measurable Yield Gains

The GAS Enviro V2 is a precision environmental control system built for growers who understand that climate consistency is the single biggest lever on yield. In a sealed or semi-sealed grow room, small fluctuations in temperature and humidity compound over a crop cycle into measurable losses in biomass, internodal spacing, and nutrient uptake efficiency. The Enviro V2 eliminates that variability. By actively regulating temperature and humidity and automating your ventilation and auxiliary equipment from a single interface, it keeps your plant microclimate within the optimal vapour pressure deficit (VPD) range from day one to harvest.

Compatible with high-performance ventilation systems including Systemair inline fans, the Enviro V2 enables balanced intake and extraction airflow, improving CO2 retention and environmental efficiency in closed-loop setups. This is the controller for growers who are serious about what their environment can do for their results.

Key Benefits

• Closed-Loop Dump Function. Automatically vents excess heat and humidity when thresholds are exceeded, protecting your crop from environmental spikes without manual intervention.
• Temperature and Humidity Control. Maintains stable grow room climate conditions across the full crop cycle for consistent plant performance.
• Built-In Fan Balancer. Synchronises intake and exhaust fans for pressure stability, improving CO2 retention and reducing hot spots.
• 2 Programmable Sockets. Control humidifiers, dehumidifiers, heaters, or supplemental lighting from the same unit.
• Centralised Control System. Manage multiple devices and environmental parameters from one interface.
• LCD Display Interface. Clear environmental monitoring and settings at a glance.
• Plug and Play Setup. Simple navigation and fast configuration. No complex wiring or programming required.
• High Load Capacity. Supports fans up to 2200W and lighting up to 1200W (2 x 600W).
• Extended Sensor Reach. 3.8m probe for accurate canopy-level temperature and humidity readings where it matters most.
• Compact Design. Space-efficient footprint for clean controller setups.

How It Works

The Enviro V2 reads temperature and humidity continuously via the 3.8m canopy probe and compares live readings against your programmed targets. When conditions drift outside your set range, the controller responds automatically: ramping fan speed up or down, triggering the dump function to vent excess heat or humidity, or activating connected equipment via the programmable sockets. The built-in fan balancer keeps intake and exhaust in sync throughout, maintaining neutral room pressure and preventing CO2 loss. The result is a grow room that manages itself, with you setting the parameters and the Enviro V2 holding them.

What Sets It Apart

Most fan controllers manage temperature. The Enviro V2 manages your entire environment. The combination of closed-loop dump function, integrated fan balancer, and dual programmable sockets means you are not just controlling airflow, you are automating the full climate response of your room. The 3.8m canopy probe ensures the readings driving those decisions are taken at plant level, not at the controller on the wall. For growers running sealed or semi-sealed systems where CO2 enrichment and VPD management are part of the strategy, the Enviro V2 is the control system that makes it all work together.

Compatible Ventilation

The GAS Enviro V2 is compatible with both AC and EC inline fans. For growers building a complete high-performance ventilation system, it pairs directly with the Revolution EC Silent Inline Fan for variable speed EC control, or the Revolution AC Inline Fan for proven AC motor performance. Both are engineered by Systemair and work within the Enviro V2 load specifications.

Frequently Asked Questions

What fans is GAS Enviro V2 Fan Controller compatible with?

GAS Enviro V2 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 V2 Fan Controller if you are retrofitting to an existing setup.

How does GAS Enviro V2 Fan Controller automate my grow room climate?

GAS Enviro V2 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 V2 Fan Controller with both my intake and exhaust fans?

Most fan controllers including GAS Enviro V2 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 V2 Fan Controller ship fast within Australia?

Yes — GAS Enviro V2 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.
