10'' round;blowing speed:4.5meters/s;drawing fresh air with Negative oxide ion;energy conservation:about half of common fan

An annular jet draws in surrounding air and alplifying it 15 times.

Mixed flow impeller: A combination of the technologies used in turbochargers and jet engines generates powerful airflow.

Brushless motor: Energy-efficient. Variable power rather than the limited settings on conventional motors.

Air inlet: up to 30l of air drawn in per second, generating primary airflow;

Easy to assemble:

Airflow control: dimmer-switch control precisely adjusts airflow power.

Oscillation Control: independent motor drives smooth 90° oscillation.

1.3 mm annular aperture: air is forced out to create the annular jet.

10mm airflow projector: directs more air towards you by focusing its exit angle.

16° airfoil-shaped ramp: generates maximum airflow velocity and volume.
