1. Strong corrosion resistance: Made of fiberglass reinforced plastic material, it is resistant to acid and alkali, moisture, and suitable for long-term use in environments with high humidity, high dust or corrosive gases (such as chemical plants, electroplating workshops, and breeding farms), with a service life much longer than metal fans.  
2. High efficiency of negative pressure ventilation: Through strong negative pressure, it can quickly extract stuffy and turbid indoor air (such as workshop fumes, odors, and moisture), while introducing fresh air. The ventilation and cooling effect is significant, especially suitable for large areas such as factories, warehouses, and greenhouses.    
3. Low energy consumption and stable operation: The design focuses on energy conservation and consumes less electricity under the same air volume; Lightweight structure with good balance performance, low noise and vibration during operation, simple maintenance, and reduced later use costs.

5. Widely applicable scenarios: In addition to industrial workshops and livestock farms, it is also suitable for agricultural greenhouses (regulating temperature and humidity), food processing workshops (high anti-corrosion requirements), outdoor large-scale work areas (such as temporary sheds on construction sites), etc., balancing practicality and environmental adaptability.
