1. Stable ventilation effect: The grille structure design is reasonable, which can guide the airflow to be evenly distributed, ensure smooth air circulation in the ventilation area, avoid local airflow being too strong or too weak, and maintain a stable ventilation effect.                                                           
2. Simple and beautiful appearance: There are various styles, including square, rectangular and other shapes. The grille lines are simple and can be matched with various decoration styles. After installation, it can be integrated into the ceiling or wall without damaging the overall beauty, and it is both practical and decorative.                                    
3. Good protection: The grid formed by the grille blades can effectively block foreign objects (such as dust, small objects, etc.) from entering the interior of the air duct, protect the core components of the air conditioning or ventilation system, reduce the occurrence of faults, and extend the service life of the equipment.                                    
4. Flexible adjustment: The blade angles of some grille vents can be adjusted to change the airflow direction according to needs, meeting the requirements of different areas for air supply angles and improving user comfort.                                     
5. Easy installation and maintenance: simple structure, diverse installation methods (such as embedded, exposed, etc.), convenient for construction operations
