Each fiber type endows filter media with unique dust filtration characteristics. To enhance filtration efficiency and performance, filter media can undergo various treatments. These treatments can extend the media's life cycle, improve dust cake release, reduce valve pulsing, ensure consistent airflow, lower differential pressure, and minimize downtime and maintenance requirements.
