Who would have thought that after 125 years lacking in innovation for the electric fan that we’d one day have a bladeless fan to keep us cool? From the same folks that brought us the bagless vacuum cleaner we now have a safer, and dare I say, “cooler” fan.
The new fan works by drawing air into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil-shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15 times. The result is a constant uninterrupted flow of cooling air.
