Mining machine filtration unit with minimised sound emission

摘要

A dust filtration unit mountable at a mining machine configured to filter airborne contaminants generated by the machine. A fan unit drives an airflow through the filtration unit as the mining machine is continuously operative. Noise emission from the filtration unit is minimised by suspending the fan unit in a floating configuration via a first, second and third elastic coupling such that the fan unit is not rigidly mounted at the machine and/or to other components of the filtration unit.
