Air surrounding the edges of the fan will also begin to flow in the direction of the breeze. This process is called entrainment. Through inducement and entrainment, Dyson claims its fans increase the output of airflow by 15 times the amount it takes in through the pedestal’s motor.
Advertising for a product isn’t a citation. That article literally just repeats Dyson’s own claims. Do you have anything that actually tests that claim?
They do not. For a given power input they produce less airflow at lower velocity than a regular fan. They’re a complete scam.
Citation needed
You made a claim first, so you should provide your citation first as well.
