Donaldson Company, a global manufacturer of filtration systems and parts, has introduced a new line of sterile air filters with its P-SRF line. The advanced technology of P-SRF filters lowers production costs while improving the purity of air used in product processing and packaging.

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 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.

When combined, these advances decrease production downtime and maintenance costs in facilities that use sterile compressed air to make products ranging from food and beverages to pharmaceuticals and medical products.

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.
