About Fan Speed Controllers
A fan speed controller is the easiest upgrade you can make to a grow room. Instead of your extraction running flat out all day, the controller adjusts fan speed to hold the temperature you set, so the room stays steady, the fans run quieter and they last longer. We stock controllers for both EC and standard AC inline fans.
EC or AC: which controller do I need?
EC fans such as Rhino EC Ultra fans need an EC controller. The Rhino 1EC runs a single extraction fan, the Rhino 2EC balances extraction and intake for negative pressure, the Rhino 2EC + RH adds humidity control with day and night settings, and the Rhino Smart EC gives you a touch screen with 1% speed steps.
Standard AC inline fans work with SMS, Super-Pro and Ecotechnics controllers. For one fan, the Super-Pro Air-Pro E1 and SMS Smart Controller are simple plug and play options. For extraction and intake together, choose the SMS Twin MK2. For bigger rooms, the SMS Hybrid Pro MK2 and Super-Pro T-Series use heavy duty transformers for silent running. The Ecotechnics Evolution controls fans, humidity and a heater from one unit.
Choosing the right size
Add up the running current of every fan you will connect and pick a controller rated above it. Running a heater too? Look for heater control, or pair your controller with one of our grow room heaters.
Fan speed controller FAQs
Will a controller make my fan quieter?
Yes. Running a fan below full speed is quieter, and transformer controllers such as the SMS Hybrid Pro and Super-Pro T-Series avoid the buzz you can get from cheaper controllers.
Can one controller run two fans?
Yes. The Rhino 2EC, Rhino 2EC + RH, SMS Twin MK2 and Ecotechnics Evolution all run extraction and intake together.
