Donaldson SRF V Series 304 Stainless Steel Sterile Air Pleated Depth Filter Element, Code 7 Connection

The P-SRF V filter element is a sterile grade, pleated depth filter element in a stainless-steel body. The improved media configuration provides excellent de-wetting capabilities and exceptionally low differential pressure drop. The sturdy stainless-steel construction permits more than 150 sterilization cycles at specified conditions and withstands high differential pressures in both flow directions.

The P-SRF V was developed for the safe and sterile filtration of air and other process gases in venting and process applications. The element is efficient to 99.99999995% at 0.2 μm and 0.02 μm, and 99.999999991% at 0.003 μm particles. The P-SRF V is reliable in extreme conditions and fulfills the stringent requirements of food and beverage industries, as well as the pharmaceutical industry.

Note: The depth filter medium is non-fiber releasing and meets the USA requirements for Food Contact Use in accordance with the Code of Federal Regulations (CFR) Title 21 211.72 latest edition and the EU requirements for Food Contact Use according to EC/1935/2004 for indirect food contact use.
