P-SRF
Sterile Depth Filter Element

Wound borosilicate sterile depth filter for process gas and compressed air — 0.2 µm absolute, min. 100 sterilisation cycles, validated to LRV > 7. The standard-duty sterile gas element for Food & Beverage and process-gas applications. For pharma sterilising-grade membrane duties, use the PTFE / PVDF line, not P-SRF.
