Vortex Thermostatic Fan Speed Controller – For Inline Fans

Set Your Temperature and Let the Fan Sort Itself Out

The Vortex Thermostatic Fan Speed Controller is the no-fuss way to regulate grow room airflow. It controls an intake or extraction fan up to 1,000W, combining an adjustable thermostat with an adjustable fan speed (dimmer). Dial in the room temperature and fan speed you want, and the built-in probe monitors your space so the controller can manage the fan for you. The housing is wall-mountable for a tidy install with the dial within reach.

Key Benefits

• Thermostatic control that manages the fan automatically from a temperature reading
• Set and forget, dial in your ideal temperature and leave the controller to manage it
• Adjustable fan speed for intake or extraction fans up to 1,000W
• Smoother, quieter operation with less noise and less wear on the fan over time

Temperature Swings and Constant Fan Fiddling

Running a fan at one fixed speed means picking your problem. Leave it on high and the room is noisy and colder than you want overnight, with humidity dropping away; leave it on low and daytime temperatures climb past the point where growth slows. Neither gives the consistency plants need, and flicking the switch twice a day is not a plan. Thermostatic control with an adjustable fan speed matches airflow to the temperature instead.

How to Use

Plug your intake or extraction fan (up to 1,000W) into the controller and mount the unit on the wall outside the tent. Set your target room temperature and fan speed on the controller, then position the probe at canopy height for the most accurate reading. Keep it clear of the lamp and the intake stream so it is not reading a hot spot or a draught, then adjust the dial a degree at a time until the room holds steady.
