Each type of fiber imparts unique dust filtration characteristics to the media. To further elevate filtration efficiency and performance, our filter media can be treated, resulting in a longer lifecycle, improved dust cake release, reduced valve pulsing, consistent airflow, lower differential pressure, and minimized downtime and maintenance.
