SKU: PES-WN Category:

The LifeTec™ PES-WN filter element provides the greatest assurance of filtration performance, stability and service life for sterile filtration and microbial stabilization.

  LifeTec PES-WN Filter Element

The outstanding performance of the PES-WN filter element is based on its state-of-the-art filtration media. The hydrophilic polyethersulfone membrane distinguishes itself by having an asymmetrically designed pore structure.

The pore size steadily decreases towards the center of the medium resulting in a highly porous structure.

This extremely durable design maintains consistent porosity and impurity retention throughout its service life without shedding or unloading contaminants.







Donaldson employees partner with customers to solve complex filtration problems from over 140 locations around the globe.
