G.A.S. Enviro4 EC Fan Controller


The Enviro4 controller by Global Air Supplies revolutionises how you manage your grow room, providing complete control over your environment to optimise growth conditions. It efficiently manages EC fan speeds and offers the flexibility to program 'on' and 'off' cycles for nearly any equipment via its four programmable sockets. This integration simplifies your setup by centralising control, allowing you to manage all aspects of your grow room environment from a single device.

With the Enviro4, you can handle up to 26 amps of power€”double the capacity of the previous version, Enviro v2€”eliminating the need for multiple controllers and reducing the risk of conflicting commands. It features an externally accessible connector socket for easy replacement of the temperature sensor probe, ensuring that all your equipment operates harmoniously to maintain optimal conditions.

Control Features:

  • Fan Management: The Enviro4 automatically adjusts EC fan speeds to maintain desired temperature and humidity levels, suitable for both intake and exhaust setups. It's designed to work seamlessly with Systemair Revolution EC fan range.
  • Environmental Regulation: The controller comes equipped with a temperature and humidity sensor, which constantly monitors your grow room. It adjusts conditions based on your predefined settings to prevent any fluctuations. The sensor's probe is also easily replaceable to ensure ongoing accuracy.
  • Versatile Equipment Control: Beyond fans, the Enviro4's four additional programmable sockets can control a range of equipment such as heaters, humidifiers, dehumidifiers, and lights. It allows for separate day and night settings for each, ensuring that your plants experience consistent environmental conditions.
  • Power Limits: Each socket can handle devices up to 2,200 watts, but for grow lights, the total should not exceed 2,400 watts due to their high startup surge.

Additional Features:

  • Dump Feature: Ideal for closed-loop environments, this feature helps manage excess heat or humidity efficiently.
  • User Interface: Features an LCD display for easy monitoring and setup, simple navigation controls, and a built-in fan balancer that coordinates the operation of intake and outtake fans.
  • Durability and Accessibility: The unit is robust with 1.2-meter power leads and a 3.8-meter probe, accommodating various setup sizes.
  • Compatibility: It works with a range of EC fans, including Systemair, Rhino Ultra EC, and Hyperfan V2 with an additional cable.

The Enviro4 is a comprehensive solution that centralizes and simplifies the control of your grow room's climate, making it an indispensable tool for serious growers aiming for the perfect growing conditions.
