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.
The table below provides a quick comparison of the auxiliary fan series based on configuration, explosion-proof requirement, and suitable mine application.
| Series | Motor / Configuration | Explosion-Proof | Suitable Mines | Key Feature |
|---|---|---|---|---|
| FK | Single motor | No | Metal mines and non-metal mines | Standard auxiliary ventilation for routine local airflow supply |
| FKD | Dual motor, counter-rotating | No | Metal mines and non-metal mines | Higher pressure support for longer ducts or higher resistance conditions |
| FB | Single motor | Yes | Coal mines, and also metal and non-metal mines with explosion-proof requirements | Safe auxiliary ventilation for explosion-proof duty |
| FBD | Dual motor, counter-rotating | Yes | Coal mines, and also metal and non-metal mines with explosion-proof requirements | Explosion-proof design with stronger pressure performance for demanding duct ventilation |
| FBC | Single motor | Yes | Coal mines, and also metal and non-metal mines with explosion-proof requirements | Reliable explosion-proof auxiliary ventilation for general underground use |
| FBCD | Dual motor, counter-rotating | Yes | Coal mines, and also metal and non-metal mines with explosion-proof requirements | Stronger explosion-proof auxiliary ventilation for higher-resistance applications |
Selected certificates include CE, ISO 9001, ISO 14001 and ISO 45001. Additional documents such as MA/KA mining product certificates, patent certificates, inspection reports and technical files can be provided upon request for project review and supplier evaluation.
