Global Air - AC Pro Step Fan Controller

The Global Air AC Pro Step Fan Controller is a high-quality transformer-based controller designed to regulate AC extractor fans in indoor growing environments. It allows growers to adjust ventilation levels easily, helping maintain stable temperatures and airflow inside a grow tent or grow room. Consistent airflow is essential in hydroponics and indoor growing systems, where proper ventilation supports plant health, nutrient uptake, and strong yields throughout vegetative growth and flowering.

Built using advanced digital controller technology with solid-state relays, the AC Pro Step Controller delivers smooth transitions between fan speeds without the loud clicking common with many traditional controllers. Its robust European-built transformer ensures reliable performance while protecting fan motors from electrical stress.

Key Benefits

• High-quality 5-step transformer fan speed control
• Silent transitions between speed settings with no clicking noise
• Reliable and efficient ventilation control for AC extractor fans
• Protects fan motors from electrical stress and voltage fluctuations
• Easy to operate with simple speed adjustments
• Durable European-built construction
• Ideal for controlling ventilation in grow tents and grow rooms

How It Solves Grow Problems

In indoor growing environments, poor ventilation can lead to rising temperatures, excessive humidity, and stale air. These conditions can slow vegetative growth, reduce nutrient uptake, and increase the risk of mould during the flowering and bloom stage.

The AC Pro Step Fan Controller allows growers to fine-tune ventilation levels to match environmental needs. By adjusting fan speeds, growers can maintain consistent airflow and temperature control throughout the grow cycle. Stable conditions support healthy plant development, improve transpiration, and help produce stronger plants with improved bud density and higher yields in hydroponic systems, coco, or soil setups.

How to Use

1. Mount the controller outside your grow tent or grow room for easy access.

2. Plug your AC extractor fan into the controller’s fan output socket.

3. Connect the controller to the mains power supply.

4. Select the desired fan speed using the controller dial.

5. Adjust the speed as needed to maintain stable temperature and airflow within your indoor growing environment.
