The Donaldson Company P-SRF air filters include two new variations: P-SRF V, a boroscilicate depth media designed for final filtration of processes and venting applications, and P-SRF X, a pleated PTFE final membrane filter designed for extreme conditions and temperatures. These filters offer a log reduction value of 7 or greater for bacteria, viruses and particles, mechanical stability and temperature resistance and fast filter drying times that minimize downtime needed for cleaning. 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. All P-SRF filter elements comply with FDA CFR Title 21 as well as the European Food Contact Regulation EC/1935/2004.
