tunnel dust removal fan

Tunnel dust removal fans are axial or centrifugal blowers designed to power ducted extraction and scrubber units in tunnel construction and mining operations. They remove dust at points of high generation.

Flow capacities range from 5,000 to 80,000 CFM, with static pressures up to 4 kPa. Robust steel or FRP housings and sealed bearings ensure reliable operation in confined, humid tunnels.

Variable frequency drives (VFDs) allow adaptive extraction, adjusting fan speed based on real-time dust concentration and pressure data to optimize energy use and maintain air quality.

Maintenance is simplified by quick-release duct connections, external lubrication ports, and removable impeller modules. Tunnel dust removal fans enhance visibility, safety, and compliance in underground passages.
