Mine Auxiliary Fans

Mine Auxiliary Fans are local ventilation fans used in mines to deliver or extract air in specific underground areas where the main ventilation circuit cannot provide sufficient airflow, especially at advancing headings such as development drifts, raises, and blind ends. Unlike a main fan that serves the overall mine ventilation network, a mine auxiliary fan is installed closer to the work area and is typically connected to ventilation ducting to direct air where it is needed.

Selection is typically based on airflow and pressure demand, duct diameter and length, resistance losses, operating mode, site conditions, and any flameproof or explosion-proof requirements. This category covers axial and counter-rotating axial auxiliary fan solutions, including FK, FKD, FBD, FB, and FBC series, to match different airflow, pressure, and safety requirements across underground conditions.

We support site-specific configuration and customization to fit real conditions, including fan size, motor power, materials, functional options, and accessories such as duct connections, transition pieces, silencers, and control or VFD solutions. With selection assistance and technical support, clients can build an efficient, safe, and reliable local ventilation system for stable day-to-day operation.
