Different fibers impart unique filtration characteristics to each media. Furthermore, filter media can undergo various treatments to boost filtration efficiency and performance, resulting in extended media life cycles, improved dust cake release, reduced valve pulsing, more consistent airflow, lower differential pressure, and minimized downtime and maintenance needs.
