Description
Variispeed Fan Controllers are easy to use, high-quality fan controllers for controlling single fans with AC motors (you will know if you have an EC fan by the hole in your pocket!).
- Adjustable Fan Speeds: Allows precise control over ventilation, letting you tailor airflow to the specific needs of your plants at different growth stages.
- Improves Climate Control: Helps regulate temperature and humidity in your grow space, ensuring a stable and healthy environment for your plants.
- Energy Efficient: Reduces energy usage by allowing fans to run at lower speeds when full power isn’t needed, saving on electricity costs.
- Easy to Use: Features a straightforward dial for smooth adjustments, making it user-friendly for gardeners of all experience levels.
- Quiet Operation: Minimises fan noise at lower speeds, creating a quieter growing environment without sacrificing performance.
- Compact and Lightweight: Small enough to fit neatly into any grow room setup, making it easy to use and store.
- Durable Construction: Built with high-quality materials to ensure long-lasting reliability, even in demanding conditions.
- Compatible with Most Fans: Works with a wide range of inline and extraction fans, offering versatility for various growing systems.
They can control the fan from 0-100% (though most fans should be run at 35% plus when using this technology) and can take up to 300W, which covers all of the RUCK fans that we sell - for other fans please check the specifications to see how much power they draw. Depending on the fan you use there may be some humming, but at this price, most people tend to put up with it...
The Variispeed is well built, simple to use and very cheap - they are a great way of taking the edge off slightly too powerful fans without the need to replace the whole unit.
