| 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 |
The distinct fibers used in each type of media impart unique dust filtration attributes. To further elevate filtration efficiency and performance, our media can undergo advanced treatments that extend the filter's lifespan, enhance dust cake release, reduce valve pulsing, maintain consistent airflow, lower differential pressure, and minimize downtime and maintenance.
