Each type of fiber endows the filter media with unique dust filtration properties. These media can be further enhanced through various treatments to boost filtration efficiency and performance, extending the filter media's life cycle, ensuring better dust cake release, reducing valve pulsing, maintaining consistent airflow, lowering differential pressure, and minimizing downtime and maintenance.
