FKD Series Counter-Rotating Mine Ventilation Fan for Underground and Tunnel
The FKD Series Mine Ventilation Fan is a counter-rotating axial flow ventilation system specifically engineered for underground mining, tunnel excavation, and industrial airflow management. This high-pressure mining ventilation fan enhances dust control, methane extraction, and air circulation in coal mines, hard rock mines, and subsurface projects. Designed for low noise, stable operation, and extended air supply distances, it is ideal for auxiliary ventilation, booster ventilation, and emergency ventilation. Its advanced engineering ensures efficient airflow control and reliability in harsh underground environments.
The FKD Series High-Pressure Mine Ventilation Fan is developed to provide targeted airflow solutions for underground chambers, mining tunnels, and confined industrial spaces. This counter-rotating axial flow ventilation system plays a critical role in coal mines, hard rock mines, and tunnel construction projects, ensuring consistent and efficient ventilation in underground workspaces.
Key Features of FKD Series Mine Ventilation Fan
Optimized airflow performance with a stable characteristic curve and broad high-efficiency range.
Low-noise operation and vibration reduction for smooth functionality in underground settings.
Extended airflow reach, making it highly effective in deep tunnel and mine ventilation.
National patent design with swept-blade counter-rotating axial flow technology (Patent No.: ZL03215439.9).
Installation and Operating Conditions
The FKD Series Mine Ventilation Fan can be installed on the tunnel floor or securely mounted on tunnel walls. If placed on the ground, the air intake (collector side) must remain free from water and debris.
The operational temperature range is -20°C to 40°C, and it is designed for altitudes up to 1000m.
The maximum allowable dust concentration in the working environment should not exceed 200mg/m³.
The power supply operates at a standard frequency of 50Hz, with voltage options including 380V/660V or 660V/1140V.
