Many advertisements are showing bladeless fans, but how do they work? The answer is that these fans actually have blades, but they are concealed in the fan’s pedestal. These types of fans suck the air into the pedestal, transport it through a tube and push it out of the front. The working method of these devices consists of several stages:
1. The machine sucks the air in. This is done by a silent motor which is usually powered by electricity.
2. The air is then accelerated, thanks to the device’s aperture. Usually, this is done by using an airfoil-shaped ramp with a certain angle which points the air in the right direction.
3. The accelerated air is drawn back in the airflow via inducement. This method is constantly repeated as the machine attracts air from behind and entrains it.
