Float dust reductions of >90% can be achieved by adding an in-line wetted scrubber to an auxiliary section fan. Coal mine operators can use this combination to reduce the possibility of a coal dust explosion in the return.
For Spanish speakers, download the same infographic with text in Spanish.
![Photo of scrubber system as installed in an underground coal mine return entry shown. The photo is taken from a perspective to represent the entire assembly. From left to right, there is a labeled wetted scrubber section, then a flexible duct that connects to the auxiliary fan that pulls air through the scrubber, then a labeled auxiliary fan. The rib and floor of the mine workings are also visible and most everything is coated in gray rock dust. There is a labeled arrow beneath the scrubber system pointing to the right to represent the airflow direction.](../UserFiles/works/images/Scrubber-FilterAndScrubberInfographics.png)
