Donaldson Introduces P-SRF Sterile Air Filters
Donaldson Company, Inc. introduces the P-SRF line of sterile air filters. The P-SRF filter line 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 reportedly deliver the following advantages:
· A log reduction value of seven or greater for bacteria, viruses and particles (down to three nanometers) to improve product and process integrity.
· Mechanical stability and temperature resistance up to 392 degrees F (200 degrees C).
· Extended life and reliability under extreme conditions, including 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.
· Superior de-wetting characteristics for faster filter drying times. This minimizes the downtime needed for clean-in-place (CIP) and sterilization-in-place (SIP) cleaning and gets production back online faster.
The P-SRF V will replace the current P-SRF N filter elements from Donaldson, while P-SRF X is an all-new PTFE membrane filter element with proprietary media and a protective stainless-steel cage housing for extreme conditions. All P-SRF filter elements comply with FDA CFR Title 21 as well as the European Food Contact Regulation EC/1935/2004.
