The unique properties of various fibers endow each filter media with distinct dust filtration capabilities. Further treatments can amplify these benefits, resulting in prolonged media lifespan, superior dust cake release, minimized valve pulsing, consistent airflow, lower differential pressure, and decreased maintenance and downtime.
