Boosted Air Supply: Increases airflow pressure through blade curvature design, extends the air supply distance, ensures rapid coverage of large spaces, and improves cooling and heating efficiency. Multi-Mode Compatibility: Suitable for air conditioning modes such as cooling and heating; optimizes airflow direction by adjusting the blade angle, such as directing downward during heating, meeting the requirements of various modes. Adjustable Wind Speed: Blade angles can be adjusted to change the air intake area, working with the motor to enable multi-speed wind settings, meeting airflow needs in different scenarios.
