1. Utilizes a fiberglass SMC molded casing that conforms to air flow characteristics, offering high airflow, high efficiency, and corrosion resistance.
2. A damper can be installed inside the duct to effectively prevent backflow, providing excellent sealing, low wind resistance, and easy installation.
3. Utilizes GOFEE's independently developed permanent magnet brushless variable frequency motor specifically designed for direct-drive fans, offering high efficiency, a wide operating range, strong load capacity, and high speed stability. The intelligent digital control and drive module with a built-in microprocessor chip facilitates 0-10V analog control and RS485 interface control. Protection rating: IP67, insulation class F.
4. The fan offers low noise, high efficiency, excellent high-voltage resistance, and stable operation.
