Air filter cartridge LifeTec™ P-SRF E

depthsterilizationstainless steel

The Donaldson LifeTec™ P-SRF E series pleated sterile depth filter meets the stringent requirements in the semiconductor and electronics industry and works reliable even under extreme operating conditions. The P-SRF E filter element offers a very high dirt holding capacity, a low differential pressure and a high temperature tolerance which is ideal for electronics​ and semiconductor manufacturing processes. The retention rate is > 99.99999995% rela­ted to 0.2 micron and > 99.99999995% related to 0.02 micron. The retention for nano-sized particles (0.003 μm) is larger than 99.999999991% as verified in a DIN EN 1822 adopted test. The sturdy stainless steel construction permits more than 160 possible sterilization cycles at specified conditions and withstands high differential pressures in both flow directions. P-SRF E sterile filter elements ensure a safe and reproducible production. Features Developed for the sterile filtration of air and gases in compressed air applications in the electronics and semiconductor industry. High retention rate (bacteria, viruses and particles) down to 3 nm (na­nometers) to ensure product and process integrity High temperature & mechanical resistance for outstanding performance, minimizes production down time and maintenance costs Suitable for sterilization, using VPHP and ozone - this leads to reduced total cost of ownership
