Automatically Adjust Your Fan Speed Based on Temperature

Designed to manage both intake and extraction fans, this intelligent controller helps maintain stable conditions without constant manual adjustments.

Simply set your desired temperature and minimum fan speed, and the controller will increase airflow as temperatures rise.

It’s an essential upgrade for growers looking to improve environmental control, reduce noise and optimise airflow efficiency.

Key Benefits

• Automatically adjusts fan speed based on temperature
• Controls both intake and extraction fans
• Maintains stable grow room conditions
• Reduces noise by lowering fan speed when possible
• Prevents temperature spikes
• Simple dial controls for easy setup

Why You Need a Fan Speed Controller

Without a controller, extraction fans typically run at full power constantly, which can lead to unnecessary noise, energy use and unstable temperatures.

The Vortex Twin Speed Controller allows your fans to run at a lower base speed, only increasing when temperatures rise above your set point. This creates a more stable environment and helps your plants grow under consistent conditions.

How It Works

Set your desired temperature using the thermostat dial, then choose a minimum fan speed.

When the grow room temperature exceeds your set level, the controller automatically increases fan speed to remove excess heat. Once temperatures drop, it returns to the lower speed setting.

This constant adjustment keeps your environment balanced without manual intervention.

How to Set Up

Plug your intake and extraction fans into the controller.

Set your desired temperature threshold and minimum fan speed using the control dials.

Position the temperature sensor at canopy height for accurate readings.

Top Tip

Set your minimum fan speed just high enough to maintain constant airflow – this keeps fresh air moving while allowing the controller to ramp up only when extra cooling is needed.
