Sterile air filters for extreme conditions

By Chemical Engineering |

The P-SRF line of sterile air filters (photo) includes two variations: P-SRF V, a borosilicate depth media suitable for final filtration of processes and venting applications; and P-SRF X, a pleated PTFE final membrane filter in a strong stainless-steel housing designed for extreme conditions and temperatures. Both filters deliver a log reduction value of 7 or greater for bacteria, viruses and particles (down to 3 nm) to improve product and process integrity. The filters are built with mechanical stability and temperature resistance up to 392°F. They perform reliably under extreme conditions, including contact with vapor-phase hydrogen peroxide (VPHP) and ozone sterilization — up to 150 cycles for the P-SRF V and 200 cycles for the P-SRF X. — Donaldson Co., Inc., Minneapolis, Minn.
