Each fiber type endows the filter media with unique dust filtration properties. Additional treatments can be applied to the filter media to further enhance filtration efficiency and overall performance. Benefits include prolonged media life cycle, improved dust cake release, reduced valve pulsing, steady airflow, decreased differential pressure, and minimized downtime and maintenance.
