# Permanent Magnet Negative Pressure Fans (Strong Suction)

1. **6 Reinforced Fiberglass Blades**

Engineered for industrial and agricultural use, the fiberglass blades deliver powerful, uniform airflow while offering exceptional corrosion resistance. Built to withstand humid, corrosive environments common in farms, factories, and coastal facilities, they operate with low noise and maintain long-term durability, reducing the need for frequent replacements.

2. **Self-Closing Louvered Shutter Design**

The automatic louver system opens fully during operation for unobstructed airflow, then closes tightly when the fan is idle. This all-in-one design prevents rain, dust, debris, and even insects from entering the unit, protecting internal components from damage, reducing maintenance needs, and extending the fan’s service life.

3. **High-Efficiency 1.1kW Permanent Magnet Motor**

Compact yet powerful, our 1.1kW permanent magnet motor outperforms traditional 1.1kW asynchronous motors in torque and energy efficiency. It delivers consistent, strong suction while consuming significantly less power, with proven long-term energy savings that drastically reduce electricity costs over years of continuous use.

4. **Versatile Applications Across Industries **

Ideal for a wide range of settings, including:

- Industrial workshops and manufacturing facilities

- Warehouses and logistics centers

- Livestock farms and agricultural facilities

- Underground parking garages

- Commercial kitchen smoke exhaust zones 

- And more commercial & industrial ventilation needs
