In our quest for optimisation, today we will talk about the direction of rotation of your centrifugal fan. 💨
When the blades rotate in the right direction, your fan unleashes its full potential, delivering optimum performance, between 80% and 100%. But beware! Spinning in the wrong direction could limit it to a modest 20%. 😯
Also, bear in mind that these fans have the peculiarity of sucking in both directions of rotation. Amazing, isn’t it?
The key is in their design. Centrifugal fans have a turbine inside with forward or backward curved blades that, when rotating, create a pressure difference. When the turbine rotates in the right direction, it generates an airflow that sucks air into the centre; when it rotates in the opposite direction, the phenomenon is repeated.
This change alters the airflow direction designed to optimise suction. As a result, the pressure generating capacity is reduced and the overall performance of the fan is reduced. In short, turning backwards can negatively affect the efficiency and functionality of the centrifugal fan.
Always remember to check the arrow indicating the direction of rotation when installing it. 🔄 A small gesture that ensures that your equipment will perform to its full potential. ✨
To check this, look at the small propeller on the back of the engine. It should rotate in the same direction as indicated by the arrow sticker. Simply turn the fan on and off quickly to confirm this.
If you need to change the direction of rotation of the motor, a common technical solution is to reverse the connection of two of the wires, generally known as phases.
