FBC Extractive Mine Local Ventilation Fan
A single-stage axial fan for negative-pressure local exhaust in underground mine workings. FBC draws contaminated air through ventilation ducting from headings and working areas to a designated return-air or exhaust route.
Select by airflow, total pressure, duct resistance, mine conditions and project safety requirements. FBC and FBCD are different configurations.
Negative-Pressure Local Exhaust Ventilation
FBC is used when contaminated mine air must be extracted from a localized underground area rather than fresh air being forced toward the face. It is normally connected to negative-pressure ventilation ducting so air, dust and gas-bearing mine atmosphere can be drawn away from the working area and discharged into the designated return-air system.
Collect contaminated air near an excavation, heading or localized working zone.
Match airflow and pressure to resistance through the complete suction duct route.
Extract Air Instead of Forcing Air
Contaminated air is collected near the excavation or localized working zone.
The fan creates suction through the duct rather than supplying positive-pressure fresh air.
A single-stage axial fan provides airflow and pressure to overcome duct-system resistance.
Extracted air is discharged to the designated return-air or exhaust route.
Single-Stage Axial Exhaust Configuration
The official page describes an axial impeller, direct drive and cylindrical steel casing. Floor or suspended mounting can be reviewed according to the site layout. Confirm final configuration against the selected model and project drawings.
FBC Series Performance Envelope
Use these values for preliminary screening. The official source page does not provide a complete standard model-by-model performance table; final selection must be checked against the required operating point and project configuration.

FBC and FBCD Are Not Interchangeable by Name
Used where one axial stage can meet required airflow and pressure for negative-pressure local exhaust.
Uses two contra-rotating stages and is generally used where greater pressure capability is required.

FBC Mine Ventilation Fan Questions
What does FBC mean?
FBC identifies an extractive axial local ventilation fan. Contra-rotating models add D and are identified as FBCD.
What is the difference between FBC and FBCD?
FBC uses a single-stage configuration. FBCD uses two contra-rotating stages and is generally used where greater pressure capability is required.
What airflow range does the source publish?
0.75–7.83 m³/s or 2,700–28,188 m³/h, with total pressure of 121–3,581 Pa.
