FKD Series Auxiliary Counter-Rotating Axial Mine Supply Fan

Product Applications: High-Temperature, Corrosion & Special Environment Customization Metal & Non-Metal Mining Tunnel & Underground

The FKD series features a compact structure for easy installation and maintenance, making it ideal for variable and space-limited underground environments. While primarily designed for coal mines, it is also well-suited for high-pressure ventilation tasks in metallurgy, non-ferrous, chemical, shipbuilding, and ceramics industries.
