Tower fans work by drawing air in and pushing it out to create a cooling breeze. Unlike traditional bladed fans, they use a rotating cylinder with angled vanes to move air.
Here's a breakdown of the process:
-
Air Intake: Tower fans typically draw air in through vents located on the sides or back of the unit.
-
Rotating Cylinder: Inside the fan is a vertical cylinder (sometimes referred to as a centrifugal fan or squirrel cage fan) with angled blades or vanes. This cylinder rotates via an electric motor.
-
Airflow Generation: As the cylinder rotates, the vanes scoop up air and force it outwards. This increases the air pressure inside the fan.
-
Air Delivery: The pressurized air is then channeled through a narrow outlet or vent that spans the height of the fan. This creates a focused, column-shaped airflow that is pushed out into the room.
-
Oscillation: Many tower fans also have an oscillation feature, where the entire fan body rotates horizontally to distribute the airflow across a wider area. This is usually achieved through a separate motor that drives the oscillating movement.
In summary, tower fans use a rotating cylinder to draw in air, increase its pressure, and then expel it through a narrow vent to create a consistent airflow, often enhanced by oscillation for wider distribution.
