Each fiber type endows the filter media with unique and highly effective dust filtration properties. Additionally, the filter media can undergo treatments to further bolster its efficiency and performance. These enhancements lead to extended life cycles, improved dust cake release, reduced valve pulsing, consistent airflow, lower differential pressure, and minimized downtime and maintenance needs.
