The "Wind Overlord" series is a large ceiling fan with a diameter of 7.3 meters independently developed by Julai Ventilation based on aerodynamic principles combined with modern aviation wing technology! It adopts the motor imported from Lenz, Germany, which has the characteristics of low speed, large air volume, low noise and low energy consumption. The large-scale imitation of natural breeze blows, and the air circulation without dead ends plays the dual functions of ventilation and cooling, effectively solving the problems of hot and humid tall spaces, air stratification, and persistent smoke and dust. It is suitable for industrial, commercial, animal husbandry and many other fields.
