**Principle of Negative Pressure Fan:** The negative pressure fan operates based on air convection and negative pressure ventilation principles. It is commonly installed in areas with poor ventilation. When running, it quickly expels stagnant hot air, odors, and smoke through negative pressure, while fresh air enters through doors, circulating within the space. This improves ventilation, cooling, and overall working environment quality.
