Donaldson P-SRF pleated filter element
The Donaldson P-SRF N sterile pleated depth filter element is used for sterile filtration of compressed air,
process air, technical gases and vent applications. The retention rate is >99.99998% related to 0.2 µm and
>99.9999998% related to 0.02 µm ensuring safe and sterile filtration of process gases. The P-SRF N provides
low pressure drop, high dirt-holding capacity, great strength, and long service life to dramatically reduce
your operating costs.
FEATURES & BENEFITS
1.Thirteen sizes and available connection options meet virtually all air purification application requirements.
2.High-quality stainless steel construction ensures excellent mechanical stability, thermal resistance up to 392F, more than 150 sterilization cycles possible at specific conditions, and is suited for Vapor Phase Hydrogen Peroxide (VPHP) sterilization.
3.Three-dimensional borosilicate depth filter media has large void volume of 95%, is chemically inert and developed specifically for the removal of contaminating bacteria and viruses.
4.This inherently hydrophobic media ensures high flow rates, an extremely low pressure drop, and excellent dewetting characteristics.
5.The validated retention of bacteria and viruses provides high safety for aseptic applications in all industries.
6.The depth filter medium is non-fiber releasing and all components meet the FDA requirements for contact with food in accordance with the Code of Federal Regulations (CFR), title 21. The filter element is manufactured according to DIN EN ISO 9001.
