FBD series

The FBD series comprises heavy-duty centrifugal and axial flow fans engineered for the rigorous demands of underground mining and tunneling applications. Built with Q345 steel casings and precision-balanced impellers, these units withstand abrasive particulate and high humidity.

Featuring backward-curved impellers, FBD fans generate static pressures up to 4 kPa while maintaining airflow rates to 100,000 CFM. Corrosion-resistant coatings and sealed bearings ensure extended service life even in moisture-laden atmospheres.

Integrated IE4 premium-efficiency motors and optional variable frequency drives (VFDs) enable demand-driven ventilation, adjusting fan speed based on real-time gas, temperature, and pressure sensor inputs. This adaptive control reduces energy consumption by up to 20% compared to fixed-speed fans.

Maintenance is simplified by split-casing designs and quick-release impeller cartridges. With explosion-proof options compliant with ATEX and MSHA standards, the FBD series delivers safe, efficient, and dependable airflow solutions for modern subterranean environments.
