- Unique Golf dimple blade reduces 15% noise level at the same RPM & airflow.
- Low Noise level from 10~22.6dBA depends on fan speed.
- Long life expectancy of 60,000 hours in 40 degree C.
- It increases fan's efficiency and reduces current consumption.
- PWM function supported, starting at low speed minimizing with very low noise level without reducing efficiency.
