Description
The Global Air AC Pro PLUS Step Fan Controller is a high-quality transformer-based controller designed to regulate AC extractor fans in indoor growing environments. It provides smooth, reliable fan speed control while maintaining stable temperatures inside a grow tent or grow room. Built with advanced digital controller technology and solid-state relays, the unit delivers silent transitions between fan speeds without the loud clicking often associated with standard step controllers.
In hydroponics and indoor growing setups, maintaining consistent environmental conditions is essential for healthy plant development. The Pro PLUS controller automatically manages fan speed to stabilise temperatures while also controlling a heater to keep the grow space within the ideal range for plant growth during both vegetative growth and the flowering stage.
Key Benefits
• High-quality 5-step transformer fan speed control
• Silent step transitions with no clicking noise
• Integrated heater control for stable temperature management
• Helps maintain ideal climate conditions in grow tents and grow rooms
• Protects AC fan motors from electrical stress
• Simple and reliable operation for indoor growing ventilation systems
• Built in Europe to high manufacturing standards
How It Solves Grow Problems
Temperature fluctuations are a common issue in indoor growing environments. When temperatures drop too low during lights-off periods or rise too quickly under grow lights, plants can experience stress that slows vegetative growth and reduces yields.
The AC Pro PLUS Step Fan Controller stabilises the environment by regulating fan speed while simultaneously controlling a heater. This balanced climate control helps maintain steady temperatures throughout the grow cycle. Stable conditions support better nutrient uptake, healthier plant growth, and improved bud density during the bloom stage in hydroponic systems, coco, or soil grows.
How to Use
-
Mount the controller outside your grow tent or grow room for easy access.
-
Connect your AC extractor fan to the fan output on the controller.
-
Connect a compatible heater to the heater output.
-
Plug the controller into a suitable power supply.
-
Set your desired temperature on the controller.
-
The controller will automatically adjust fan speeds and activate the heater when required to maintain stable environmental conditions.
