What makes the difference in the material and number of fan blades?

The more blades, the less vibration, quieter wind cutting noise, and a softer airflow.
The fewer blades, the more vibration, louder wind cutting noise, and stronger airflow.
Our blades are made of engineering plastic steel (Nylon 66 + glass fiber reinforced material), characterized by lightweight, acid and alkali resistance, deformation resistance, toughness, and large airflow. This reduces the motor load, achieving energy-saving effects.
