Aokai provides filter media solutions for abrasive, corrosive, high-temperature, and explosive dust filtration, and specializes in dust collection processes in asphalt mixing, chemicals, cement, metals, power generation, waste-to-energy, renewable energy, woodworking, and many other demanding industries.
Choosing the right filter media with its corresponding characteristics that are best suited for your application can help boost the performance and longevity of your dust filtration system.
| Fibre types | Weight | Continuous temperature | Peak Temperature |
| PE | 450-600 | 130ºC | 150ºC |
| PAC | 500-550 | 125ºC | 150ºC |
| PPS | 500-650 | 160ºC | 190ºC |
| Aramid | 400-600 | 204ºC | 250ºC |
| PTFE | 750-800 | 240ºC | 260ºC |
| P84 | 500-550 | 240ºC | 260ºC |
| GL | 750-900 | 240ºC | 260ºC |
Different fibers provide each media with different dust filtration characteristics. Filter media can be further treated to improve their filtration efficiency and performance, such as lengthened filter media life cycle, better dust cake release, reduced valve pulsing, more consistent airflow, reduced differential pressure, and reduced downtime and maintenance.
