Each type of fiber imparts unique dust filtration properties to the media. Further treatments can enhance these properties, resulting in increased filter media lifespan, improved dust cake release, minimized valve pulsing, stabilized airflow, reduced differential pressure, and lowered downtime and maintenance costs. Choose Aokai for superior filtration efficiency and performance.
