Abstract (en)
A dust filtering unit mountable at a mining machine (100). The filtering unit comprises a filtration duct (113) having a scrubber unit and demister where airflow through the filter unit is driven by an exhaust fan (114). Noise emission from the fan is reduced by a first flexible coupling (502) positioned between the fan unit and a filter duct and a second flexible coupling (703) mounting the fan unit at a filter support frame (109).
