Donaldson Company, Inc. has introduced the P-SRF line sterile air filters.
The technology used to create Donaldson’s P-SRF filters should lower production costs while improving the purity of air used in product processing and packaging.
The P-SRF filter line includes two new 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 stainless-steel housing designed for extreme conditions and temperatures.
Both filters deliver the following advantages:
• A log reduction value of 7 or greater for bacteria, viruses, and particles (down to 3 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.
