Each fiber type endows the media with distinct dust filtration properties. Advanced treatments can further optimize these media to elevate filtration efficiency and performance-resulting in prolonged filter media life cycles, superior dust cake release, minimized valve pulsing, consistent airflow, reduced differential pressure, and diminished downtime and maintenance requirements.
