Simple & Effective Fan Speed Management and Temperature Control
GSE fan speed controllers adjust the speed of your extraction system to keep grow room conditions regulated in real time. Choose from an array of models that each come with their own benefits, including humidity settings, hysteresis (responsiveness) and negative pressure settings (altering the difference between your intake and extraction).
How GSE Fan Speed Controllers Work
GSE Temp & Minimum Fan Speed (1 Amp)
The simplest controller in the range, with a single socket for an out-take fan. It features two knobs: one sets the room temperature and the other sets the minimum fan speed.
GSE Temp & Max / Min Hysteresis Speed (2.5 Amp)
This controller is the bigger brother of the model mentioned above. It comes with the same features, but also includes two extra knobs. One of these knobs regulates the maximum fan speed. This is useful when running a larger fan than needed because you can prevent it from hitting its full capacity (if necessary). The other knob allows you to set the hysteresis. Think of hysteresis as 'responsiveness'. It tells the controller how far conditions can deviate before fan speeds are altered.
GSE Temp & Negative Pressure (2 Amp)
There are two sockets on this controller: one for an intake fan and one for extraction. It comes with three knobs: one for setting your desired room temperature, one for the minimum fan speed and one for the 'negative pressure setting'. When you have negative pressure, it effectively means that you're pulling more air out of the room than you are drawing in, which is useful for containing smells. In this instance, the negative pressure knob regulates the difference between your intake and extraction. The further to the right you turn this knob, the more negative pressure you will have. Turning it all the way to the right will turn your intake off altogether.
GSE Humidity, Temp & Negative Pressure (3 Amp)
This unit is similar to the model mentioned above, but it also comes with a humidity setting. Choose your setting and the controller will regulate fan output according to both temperature and moisture levels.
